Abstract

The genus Entada (Leguminosae subfam. Mimosoideae) in Taiwan is revised. Two species, Entada phaseoloides (L.) Merr. and E. rheedei Spreng. are recognized, of which the former is divided into subsp. phaseoloides and subsp. tonkinensis (Gagnep.) H. Ohashi (new combination). Entada phaseoloides subsp. phaseoloides corresponds to E. koshunensis Hayata & Kaneh. and E. parvifolia Merr. previously recognized in Taiwan, while E. phaseoloides subsp. tonkinensis is identical with E. phaseoloides as recorded from northern and central Taiwan. Entada formosana Kaneh. is referable to E. rheedei Spreng., which is the correct name for E. pursaetha DC. adopted in previous works in Taiwan. Entada koshunensis Hayata & Kaneh. is typified. Entada pursaetha var. formosana (Kanehira) F. C. Ho is an illegitimate name.
