ItemTrematolobelia: Seed Dispersal; Anatomy of Fruit and Seeds(University of Hawai'i Press, 1962-01)The endemic Hawaiian genus Trematolobelia (Lobeliaceae, or Campanulaceae, subfamily Lobelioideae) was erected on the basis of its distinctive fruit. This fruit has a seed-dispersal mechanism unique in the family. Assertions have been made by some workers that holes in the fruit wall are the work of insects, and are not related to the dispersal mechanism. This contention has been adequately disproved by other investigators, but, in fact, the precise nature of the dispersal mechanism and the anatomical structure responsible for its action have never been adequately described. In addition, the present study reveals the potential taxonomic use of capsular anatomy, a feature of importance because various authors recognize one, two, or three species in the genus. These species are based largely on floral features or foliar characteristics, and not on those of the fruit. Unusually good material of Trematolobelia collected by the writer during the summer of 1958 provides a sufficient basis for presenting the features mentioned above in some detail.

ItemTypes of Occurrence of Nontronite and Nontronite-like Minerals in Soils(University of Hawai'i Press, 1962-01)Nontronite, the iron-rich dioctahedral mineral of the montmorillonite group, is rarely found in soils. A number of montmorillonite clays having a high content of iron oxide have been found in subsoils. These occurrences are located at Toowoomba, Queensland, Australia; Waipata, South Island, New Zealand; Molumolu, Fiji; and at a number of sites in the Hawaiian Islands. These clays occur as relatively pure mineral aggregates and therefore are well segregated from their matrix. The type of occurrence provided material of homogeneous chemical and mineral compositions. The iron oxide content of these clays ranged from 9 to 32 per cent and indicates a wide range of iron substitution in the octahedral position. These clays occur under a wide range of climatic conditions, as evidenced by rainfall variation of 13 to 120 inches per year. Likewise, they occur in both early and late stages of weathering and, because of that, they occur in different mineral associations of primary minerals, other 2: 1 clays, kaolin, iron oxides, and bauxite.

ItemFish Poisoning: A Problem in Food Toxication(University of Hawai'i Press, 1962-01)Interest in poisonous fishes has intensified greatly in recent years. World Wat II brought many Americans and Europeans to tropical areas of the world where fish poisoning is common. Also, interest in the welfare of native populations of the Pacific islands has developed widely, and there is an impression that fish poisoning is increasing. In spite of an extensive literature, there is considerable confusion on the subject.

ItemNotes on Some Eastern Pacific Species of Phialidium (Leptomedusae)(University of Hawai'i Press, 1962-01)A collection of Phialidium was sent to me by Dr. E. C. Roosen-Runge, University of Washington, Seattle, who wanted my opinion on their specific affinity. They were collected at Friday Harbor in Puget Sound, some few in August 1959, a great number in June 1960. They all belong to one species and agree perfectly with the species which was described by Murbach and Shearer (1903) under the name Phialidium gregarium (A. Agassiz). It is questionable, however, whether the medusa observed and carefully described by Murbach and Shearer really belonged to the same species, which was briefly described by Agassiz as Oceania gregaria.
