Item type: Item , Consequences of the loss of traditional knowledge : The risk of injurious and toxic plants growing in kindergartens(Botany Department, University of Hawaii at Manoa, 2012) Cuadra, Vanesa Pérez; Cambi, Viviana Nora; Rueda, María de los Ángeles; Calfuán, Melina LorenaThe plant kingdom is a producer of poisons from a variety of toxic species. Nevertheless prevention of plant poisonings in Argentina is disregarded. As children are more affected, an evaluation of the dangerous plants present in kindergartens, and about the knowledge of teachers in charge about them, has been conducted. Floristic inventories and semi-structured interviews with teachers were carried out at 85 institutions of Bahía Blanca City. A total of 303 species were identified, from which 208 are considered to be harmless, 66 moderately and 29 highly harmful. Of the moderately harmful, 54% produce phytodematitis, and among the highly dangerous those with alkaloids and cyanogenic compounds predominate. The number of dangerous plants species present in each institution varies from none to 45. Kindergartens have no landscaping plan and the majority of teachers ignore the existence of toxic plants. Appropriate actions integrating education, prevention and valuation of the natural environment are needed.Item type: Item , The transplanted Peruvian culture in Rome : An assessment through images(Botany Department, University of Hawaii at Manoa, 2012) Matos-Soto, Yarissa K.; Savo, ValentinaPeruvian immigrants in Rome represent a large community, creating microcosms where people retain strong interpersonal and family bonds. The aim of this photo essay is to portray, through images, some of the transplanted cultural aspects of Peruvians in Rome and to define the ethno-botanical uses of plants that are still present. An ethno-botanical study was carried out during Spring and Summer 2011 in the city of Rome with Peruvian migrants established in Italy for at least 10 years. We used a snowball sampling approach visiting local markets, restaurants and churches, performing semi-structured interviews about uses of medicinal and food plants. We looked for the presence of culturally important plant species, taking note of the maintenance, replacement, incorporation and discontinuation of ethno-botanical uses. A total of 21 informants were interviewed reporting the uses of medicinal and food plant species still present in Rome. Many plants are still used for medicinal (38 species) or food purposes (35 species), while fewer plants are used as nutraceuticals (7 species). Medicinal uses described are, sometimes, associated with rituals and spiritual convictions. The relatively high number of food species still present in Rome could be interpreted by the fact that they are more easily accessible and that some are cultivated in Italy. However, informants generally prefer plants that originate from Peru even if sometimes they found fault about the quality of imported plants. Peruvian immigrants were found to attempt to adhere to their cultural identity, in the use of plants, trying to conserve their pre-migratory traditions as much as they can.Item type: Item , Traditional medicinal plants in two urban areas in Kenya (Thika and Nairobi) : Diversity of traded species and conservation concerns(Botany Department, University of Hawaii at Manoa, 2012) Njoroge, GraceIn Kenya there is a paucity of data on diversity, level of demand and conservation concerns of commercialized traditional medicinal plant species. A market study was undertaken in two urban areas of Central Kenya to identify species considered to be particularly important in trade as well as those thought to be scarce. The most commonly traded species include: Aloe secundiflora Engl, Urtica massaica Mildbr., Prunus africana (Hook.f.) Kalkm, Melia volkensii Gürke and Strychnos henningsii Gilg. Aloe secundiflora, P. africana and Strychnos henningsii were found to be species in the markets but in short supply. The supply chain in this area also includes plant species already known to be rare such as Carissa edulis (Forssk.) Vahl and Warburgia ugandensis Sprague. Most of the suppliers are rural herbalists (who harvest from the wild), while only a small proportion of the raw materials come from domesticated species. Key challenges facing the herbal industry in the region were identified and presented.Item type: Item , Ginkgo, apricot, and almond : Change of Chinese words and meanings from the kernel’s perspective(Botany Department, University of Hawaii at Manoa, 2012) Kirschner, Roland; Hsieh, Shelley Ching-yuThe term /apricot/ is associated with the fleshy part of the fruit in Chinese and European languages, such as English and German, whereas in Chinese /almond/ and /ginkgo/ are associated with a kernel removed from a hard shell and classified as nut-like. Historically, the modern Chinese for ginkgo, commonly translated as silver apricot replacing the older name meaning duck foot, has appeared only since the Song period (960-1279 AD). The apricot, however, has played an important role in Chinese for more than 2000 years. The element apricot which occurs in the contemporary Chinese term for gingko is considered to be derived in a technical terminology from the use in Chinese medicine of unshelled apricot seeds. In contemporary Chinese, the term xingren (unshelled apricot seed) has changed its meaning which now is unshelled almond seed. This change suggests that silver almond is a more adequate modern translation for ginkgo than silver apricot.Item type: Item , An ethnobotanical study of medicinal plants in Asgede Tsimbila district, Northwestern Tigray, Northern Ethiopia(Botany Department, University of Hawaii at Manoa, 2012) Zenebe, Girmay; Zerihun, Mohammed; Solomon, ZewdieInvestigation and documentation of the status of medicinal plants and associated knowledge was conducted in Asgede Tsimbila district, northwestern Tigray, northern Ethiopia. Data was collected and evaluated with a questionnaire survey, semi-structured interviews, field observations, direct matrix ranking, preference ranking, abundance scores, and vegetation surveys. Sixty-eight medicinal plant species used to treat 50 different ailments (in humans and livestock) were recorded. Leaves are the most commonly collected plant parts for medicinal purposes. Much of the ethno-medicinal knowledge is concentrated in elderly members of the community. The medicinal plants are facing threats from agricultural expansion, wood extraction and overgrazing. Consequently, abundance of medicinal plant resources is declining with time. Furthermore, effort to conserve and cultivate medicinal plants is virtually non-existent. Thus, participation of the local people and awareness creation on sustainable utilization and management of these resources is vital.Item type: Item , Comparative analysis of indigenous knowledge on use and management of wild edible plants : The case of central East Shewa of Ethiopia(Botany Department, University of Hawaii at Manoa, 2012) Feyssa, Debela HundeQuantitative ethnobotanical analysis of indigenous use and management practices of wild edible plants (WEPs) by transhumant and settled farmers was conducted to compare WEPs and associated indigenous knowledge (IK). Household interviews, key informant discussions, focus group discussions, field explorations and multistage direct matrix rankings were carried out to identify WEPs in six study sites of two districts in semiarid East Shewa, Ethiopia. Participant observations were made to identify local strategies of management of WEPs. The results showed that from 40 WEPs, 35 (87.5%) of them were also used for forage/fodder, and 37 (92.5%) for fuel wood. Forest is a common habitat for collection of these plants. Jaccard’s Similarity Coefficient of the three use categories were 44.2%, 46.9% and 45.6% respectively. No gender differentiation was observed regarding their knowledge of habitats of WEPs collection. 42.2% of transhumant informants attested that intergenerational transfer of IK is the responsibility of the entire community while in the case of settled farmers this is left to fathers and mothers (23.3%). There were significant variations in transferring IK (P<0.05) between the two communities. Transhumants conserve WEPs in pasture land and protect vegetation while settled farmers employ traditional dryland agroforestry, living fences and farm boarders. Study communities have significant variation in their preference for WEPs (P<0.05). The people showed greater preferences for five WEPs. The prioritized WEPs and associated IK and practices should be considered in planning conservation and sustainable use of WEPs by integrating the variations and complementing with appropriate modern practices.Item type: Item , Important woody plant species, their management and conservation status in Balawoli Sub-county, Uganda(Botany Department, University of Hawaii at Manoa, 2012) Tabuti, John R.S.Woody plant species are threatened in Uganda. To conserve these species there is need to generate information that may be used to design management plans. This study was conducted in Balawoli Sub-county, Kamuli District, Uganda between July 2009 and January 2010. We addressed four questions: (1) which woody species are most preferred? (2) what is the conservation status of these species and for which species have changes in local availability been observed? (3) what management practices exist for woody species? and (4) what tenure rights exist for woody plants? Data were generated through guided questionnaire interviews. Seventeen species are valued most within the community. These species are multipurpose and altogether have 25 different uses for the community. The most frequently harvested products are edible fruits, firewood and timber. The value of these species as a source of income is low. Milicia excelsa (Welw.) C.C. Berg, Albizia coriaria Welw. ex Oliv., Combretum molle R. Br. ex G. Don, Terminalia glaucescens Planch. ex Benth., Coffea spp., Combretum collinum Fresen. and Citrus spp. are becoming scarce. However, Artocarpus heterophyllus Lam., Mangifera indica L., Ficus natalensis Hochst., Citrus sinensis (L.) Osbeck, Acacia sp., Senna siamea (Lam.) H.S. Irwin & Barneby, Eucalyptus spp., Pinus spp., Carica papaya L. and Lantana camara L. are increasing in abundance. The main factors leading to the scarcity of some species include over-harvesting, destructive harvesting, pests, poor planting of trees by farmers, and droughts. The key factors contributing to some species’ success are that the species are planted, drought resistant, regenerate naturally, easy to manage, mature fast, available as seedlings. Farmers maintain 51 woody species that they plant or retain when found growing naturally on their land. Some farmers are constrained in planting trees by lack of seedlings, pest infestations, drought and lack of land. Species are managed in crop fields, the courtyard and home garden. Men own trees in the homestead, are more involved in tree management and selling of tree products, than women.Item type: Item , Ethnomedicinal uses of Sthalavrikshas (temple trees) in Tamil Nadu, southern India(Botany Department, University of Hawaii at Manoa, 2012) Gunasekaran, Mariappan; Balasubramanian, P.Worship of plants is practiced throughout the world and is well established from pre-historic periods in India. In Tamil Nadu state, India this customary practice follows with religious faiths and culture. One such religious worship is known as Sthalavriksha (sthal: locality, vriksha: tree) in temples. Very few field studies have been conducted on Sthalavriksha practice and its role in social, ecological and environmental impacts of local people. In particular, ethnomedicinal uses on Sthalavrikshas, occurring in the temples of Tamil Nadu have been unexplored. A survey was conducted at 1165 ancient temples of the state and revealed the occurrence of 112 plant species during 2002-2006. At the time of study, several ethnomedicinal uses of 101 Sthalavriksha species were recorded by both direct observations and referred to by devotees, priests and Nattuvaidyas (traditional healers) in the temples.Item type: Item , Olonā (Touchardia latifolia Gaud.) : Cultivating the wild populations for sustainable use and revitalization of cultural Hawaiian practices(Botany Department, University of Hawaii at Manoa, 2012) Wichman, Juliana MikioiOlonā (Touchardia latifolia Gaudich.) is an endemic Hawaiian plant used by the Hawaiians to make some of the strongest cordage in the world. Within the ahupua'a of Hā'ena on Kaua'i, there are wild populations of olonā growing however, no one knows how to manage or prepare the fibers. Due to the mission of Limahuli Garden to perpetuate traditional cultural knowledge as well as to grow and perpetuate native Hawaiian cultural plants, a long-term project to cultivate and teach community members sustainable use of olonā will not only strengthen the community, but perpetuate a traditional Hawaiian skill, which is slowing being lost. Within the scope of this experiment, I specifically looked at three populations to determine which growing conditions produced the strongest cordage. I hypothesized that Limahuli Valley has cultivatable olonā and ideal growing condition would produce plants that had stronger fibers. Collecting individuals from three different growing conditions, a modified tensile strength test was designed and two ply cordage of 25 cm long, comprised of 6, 12 and 24 individual fibers refuted my hyposthesis, but lead me to re- hypothesize that stem diameter (age of plant) rather than environmental growing conditions effect the fiber strength. I concluded that Limahuli Valley has a good population of olonā, which if managed properly, stronger fibers can be obtained and lead to the establishment of a successful community population.Item type: Item , Ethnobotany of some selected tree species in Southwest Cameroon(Botany Department, University of Hawaii at Manoa, 2012) Egbe, Andrew Enow; Tabot, Pascal Tabi; Fonge, Beatrice AmboAn ethnobotanical investigation was carried out in 12 villages in Manyu and Fako Divisions, South-western Cameroon to determine economic potentials and priorities of eight non-timber forest products (NTFPs) tree species and three tree crops. Gross farmer income in Manyu was found to be 30% from NTFPs and 70% from established tree crops, while in Fako it was 15% and 85% respectively. The yield of tree crops (160-1047 kg/farmer/year) was higher than NTFPs (0.3-273kg/farmer/year). Some 21 diseases were treated using 10 tree species. Farmers assigned highest priority for NTFPs to Irvingia gabonensis (Aubry-Lecomte ex O’Rorke) Baill., Ricinodendron heudelotii (Baill.) Heckel, Dacryodes edulis (G. Don) H.J.Lam, Irvingia wombolu Vermoesen, Cola lepidota K. Schum. and Garcinia kola Heckel for their cultural and medicinal values implying potential need for their conservation.Item type: Item , Sambucus—Intercultural exchange and evolution(Botany Department, University of Hawaii at Manoa, 2012) Austin, Daniel FrankThe plant Sambucus, called elder or elder-berry in English, has been associated with major and minor deities longer than history records. In contrast to gods and goddesses, other applications of sambucus are made in more secular ways. Sambucus and its variants have been applied to five entities—plants, a musical instrument (sambuce, שׂבּבָא), a military device (sambuca, σαμβύκῆ), a sailing vessel (sambuq, sanbuq, زنبق), and a liquor (sambuca, zammut). Each of these connotations is separated, some slightly and others markedly, from the others by fragmented historical records. While the most ancient application known is for the musical instrument, the designation of a plant is not much, if any, younger. The war machine is almost the same age as the plant tradition. Considerably more recent are the labels of a ship and alcoholic drink. This synopsis puts these records together to reveal a history of intercultural exchange and the evolution of terminology.Item type: Item , Zhombwe (Neorautanenia brachypus (Harms) C.A.Sm.) – A recent discovery for mitigating effects of drought on livestock in semi-arid areas of Southern Africa(Botany Department, University of Hawaii at Manoa, 2012) Murungweni, Chrispen; Andersson, J.A.; van Wijk, M.T.; Gwitira, I.; Giller, K.E.In semi-arid areas drought results in cattle death making people vulnerable to poverty. Drought conditions are set to increase as climate change is increasingly becoming an important threat to food security. In southern Africa, people recently discovered Neorautanenia brachypus (Harms) C.A.Sm., as an important medicinal feed that they now use to help cattle survive drought. N. brachypus was evaluated with the aim of providing scientific substantiation of peoples’ claims by determining the extent of its use, feed and anthelmintic value, and the ecological characteristics that explain its distribution. Information on characteristics and use of N. brachypus was gathered from focus group discussions and a semi-quantitative survey that employed structured interviews with both closed and open questions. The results showed that N. brachypus is used during drought by 59% of cattle owners, 14.5% do not use it because they have alternative grazing, and 26.5% did not know it can be used as cattle feed. Feed value of N. brachypus was evaluated as well as the anthelmintic value in the feeding trials with cattle and goats. N. brachypus contains adequate nutrients to maintain ruminant livestock during a drought. Infected animals fed on N. brachypus ended with less strongyloid worm infection in small ruminants (P < 0.05) and in large ruminants (P < 0.01) similar to animals dosed with the conventional recommended drugs. In the natural environment, N. brachypus was more commonly found in eutric vertisols and chromic luvisols than in ferric arenosols and leptosols, more in open spaces than in closed forests and more in cultivated areas than in naturally vegetated areas. It grows in a range of different types of soils and management affects its abundance. Ethnobotanical studies can offer important options on adaptation of human livelihoods to climate change.Item type: Item , Identification and use of plant material for the manufacture of New Zealand indigenous woven objects(Botany Department, University of Hawaii at Manoa, 2012) McCallum, Rua Elizabeth; Carr, Debra JulieSignificant collections of objects manufactured by Māori are held, prized and exhibited by cultural institutions such as the Bishop, British, Field and Pitt Rivers Museums; and Te Papa Tongarewa (Museum of New Zealand). This article describes plant material(s) used to construct woven objects from New Zealand by gathering mātauranga Māori (traditional knowledge) and diverse interdisciplinary academic literature. This article is written from an insider perspective predominantly using southern Māori[i] terminology and names; translations and a glossary are provided. Plant descriptions, harvesting, processing and use are discussed; thereby informing the researcher and affording appropriate respect and representation to the plant from which the object is derived.Item type: Item , Ethnobotany of Dacryodes edulis (G. Don) H.J. Lam in Southern Nigeria 1 : Practices and applications among the Yoruba-speaking people(Botany Department, University of Hawaii at Manoa, 2012) Omonhinmin, Conrad AsotieDacryodes edulis (G. Don) H.J. Lam or eleme is widely used among Yoruba speaking people of Nigeria. The fruit is the major part utilized for food; eaten singly or with a number of other foods. The pulp oil complements common edible oils. Considered rich with medicinal properties; the plant parts is engaged singly or with other plants for treating several illness and diseases including malaria, dermatological, oral and ear conditions, hypertension, leprosy, labor pain, retarded growth and epilepsy in children. Viewed as a symbol of “fruitfulness” and of “peace” the plant parts are employed for both religious and sociocultural activities such as warding off evil spirits, worship of gods, communal festivals, marriage, naming and settlement ceremonies. The wood is used for carpentry, road and shelter construction. The stem exudates act as glue, as well as for production of cosmetics alongside the fruit oil. The tree crown serves for apiculture as well as for shade.Item type: Item , Traditional knowledge of processing and use of the Himalayan giant nettle (Girardinia diversifolia [Link] Friis) among the Gurungs of Sikles, Nepal(Botany Department, University of Hawaii at Manoa, 2012) Gurung, Anup; Flanigan, Hailey; Ghimeray, Amal Kumar; Bista, Rajesh; Gunrung, Om PrakashThe Himalayan giant nettle (Girardinia diversifolia (Link) Friis) has been widely used throughout the mountainous regions of Nepal as a source of fiber (puwa) for weaving ropes, thread, porter’s tumplines, mats, sacks, and bhangra (a piece of traditional Gurung clothing). Ethnic groups such as Gurungs, Magars, Rais and Tamangs are the major exploiters of puwa fiber in Nepal. This study investigates the traditional knowledge of the processing and use of puwa fiber among the Gurungs of Sikles, in the trans-Himalayan region of Nepal. Puwa products have much cultural value for Gurungs in Sikles. Women are responsible for most of the puwa related activities and most of the woven products are used within households. Although puwa has become established as an important non-timber forest product for generating income among rural communities in the mountainous and Himalayan regions of Nepal, its economic potential has yet to be realized in Sikles.Item type: Item , Ethnobotany of Pentadesma butyracea in Benin : A quantitative approach(Botany Department, University of Hawaii at Manoa, 2012) Avocèvou-Ayisso, Carolle; Avohou, T.H.; Omorou, M.; Dessou, G.; Sinsin, B.Integrating ethnobotanical knowledge in the development of management and conservation strategies of indigenous plant resources is critical to their effectiveness. In this paper, we used four plant use indices to assess how the plant use knowledge of a multipurpose tree (Pentadesma butyracea Sabine) varies across different sociolinguistic groups from two geographical areas of Benin, and how these variations may influence the species’ conservation and utilisation strategies. Seven sociolinguistic groups namely the Anii, Nagot, Kotocoli, and Fulani in the central part, and the Waama, Ditamari and Natimba in the northwestern part of the country were considered. We determined the reported use value of the plant parts, the plant part value, the specific use and the intraspecific use value for each sociolinguistic group. The various communities showed different interests in the plant organs they used. Nagot people showed the best plant use knowledge (highest use value) for P. butyracea bark and roots, two organs critical to the plant survival. Sociolinguistic groups living in the same geographical area shared similar plant part values, likely because of knowledge exchanges through social interactions. The observed intercultural convergences of uses may be a starting point of the selection of parts of the species for phytochemical, biological and pharmacological studies.Item type: Item , Uras : Medicinal and ritual plants of Serampas, Jambi Indonesia(Botany Department, University of Hawaii at Manoa, 2012) Hariyadi, Bambang; Ticktin, TamaraDocumenting indigenous healthcare practices provides insight into how human communities have adapted to their local environments and can guide culturally appropriate medical care. The Serampas inhabit the border of Kerinci Seblat National Park, Sumatra, Indonesia, and the only ethnobotanical study carried out there was in 1783. We identified the Serampas’ conceptions of health and illness and the medicinal and ritual plants they use; and assessed how this has changed over the past two centuries. Participant observation and in-depth interviews were carried out with 36 respondents. The Serampas conceive of health and illness to be caused by external and internal factors and recognize obat rajo (king’s medicine) and obat ditawar (enchanted medicine). They use > 127 medicinal plant species, which overlap with their 32 species of ritual plants. Most medicinal plants are gathered from shifting cultivation fields and secondary forests, > 50% are cultivated, and 40% are also food. The Serampas use 50% of the medicinal plants recorded in 1783.Item type: Item , The point of spinifex : Aboriginal uses of spinifex grasses in Australia(Botany Department, University of Hawaii at Manoa, 2012) Pitman, Heidi T.; Wallis, Lynley A.For thousands of years spinifex grasses were utilized by Indigenous Australians, most commonly for the production of resin that was then used as a hafting adhesive. While varying levels of knowledge about this particular use are retained in Indigenous communities, museum collections serve as a valuable repository of little known information about a multitude of other uses of spinifex including ornamental, medicinal, structural and ceremonial functions. In this paper we describe the range of uses of spinifex, based on examinations of objects and photographs held in various museum collections, coupled with reviews of the ethnographic and ethnohistoric literature. This study (1) brings together disparate sources of knowledge about Indigenous uses of spinifex that are not well known among the scientific community and (2) demonstrates the value of museum collections for Indigenous communities seeking to ‘reconnect’ with aspects of so-called ‘lost traditional culture’.Item type: Item , The Ethnobotanical Study of an Edible Freshwater Red Alga, Lemanea fluviatilis (L.) C.Ag. from Manipur, India(Botany Department, University of Hawaii at Manoa, 2012) Bhosale, Rahul A.; Rout, Jayashree; Chaugule, Bhupal BaburaoAn ethnobotanical study of an edible fresh water red alga Lemanea fluviatilis (L.) C.Ag. was carried out in the Thoubaldistrict of Manipur State, India. The alga locally known as nungsham, due to its hair like growth on stone, grows profusely in the rocky and shallow river beds of the Chakpi and Manipur rivers. In earlier reports, the alga was misidentified as Lemanea australis. Harvested by the women of the Meitei, Kuki and Kuki-Chin-Mizo communites, the sun dried alga is sold in the local market. The dried filaments are eaten with major meals. A total of 23 strategically selected informants have been interviewed through structured questionnaires to obtain indigenous knowledge about the alga and its uses. Detailed morphological and reproductive features are described to reveal the correct taxonomic status of the species. Some ethnopharmacological information is also incorporated.Item type: Item , Adoption of agroforestry systems by farmers in Masaka district of Uganda(Botany Department, University of Hawaii at Manoa, 2012) Sebukyu, Vincent B.; Mosango, MbokuyoHigh population density in Masaka district, Uganda, has led to increased pressure on land. This has resulted in reduced arable land and decreased soil fertility. In view of this, the Vi-Tree NGO Project has initiated a study to investigate the adoption of agroforestry systems by farmers in Masaka district with focus on the types of agroforestry systems practiced, incorporation of multipurpose tree and shrub species, crops grown, farm land size and land ownership, production and marketing problems, and the main items on which families expend money on. Data was collected using open-ended questionnaire interviews administered to 88 farmers randomly selected throughout the 22 subcounties of Masaka district. The results were analyzed using descriptive statistics. The findings showed that the main agroforestry systems practiced are agrosilvopasture, agrosilviculture and silviculture. The study revealed that 81 woody species (75 trees and 6 shrubs) are used. 69% of these are indigenous. The most important families are Fabaceae, Moraceae, Euphorbiaceae, Combretaceae and Myrtaceae. Bananas, cassava, beans, vegetables, maize and coffee are the main crops grown. The majority of farmers hold small farm lands (1-3 acres). Primary production problems are pests and diseases while marketing problems are many including low prices, long distances from village to farm, lack of buyers and price fluctuations. The main items they spend money on are school fees, medicines, and essential commodities. The adoption of agroforestry systems by farmers is relatively high in Masaka district. This is probably due to high demand for land, soil fertility decline, erosion problems, and demand for woody products (e.g., timber, fuel wood, and fodder, food), contact with the Vi-Tree NGO Agroforestry Project extension agents, and need to increase crop yield. High levels of personal land ownership has probably contributed to the adoption of agroforestry systems to promote long-term production.
