Abstract: Samples of roots and root-zone soil from the threatened species Argyroxiphium
sandwicense subsp. macrocephalum and the endemic species Dubautia
menziesii, both members of the Asteraceae, were collected in a tropical alpine
area in Haleakala National Park, Maui, Hawai'i, and examined for arbuscular
mycorrhizal fungi (AMF). All root samples exhibited the Paris-type of mycorrhizae
with arbuscules produced on hyphal coils, and all soil collections included
spores of AMF. Spores of Acaulospora, Entrophospora, Glomus, and Scutellospora
spp. were recovered from this site.
