This paper provides a brief account of 31 plants associated with herba
l remedies among the Hayas, a tribe of Kagera region, Tanzania. Report
s from informants were obtained during field studies in June 1987. For
each species are given the botanical name, vernacular name, collectio
n number, locality, habit, distribution and medical uses. The data are
compared with information from literature for medical uses, and liste
d isolated constituents and pharmacological effects. The Hayas have ha
d a rich herbal folklore, but this is fading due to increasing accultu
ration and depletion of plant cover.
