Taxonomic notes on Mucuna (Fabaceae: Papilionoideae) of Taiwan
摘要
This study unveils a novel variety of Mucuna macrocarpa, named M. macrocarpa var. oui, discovered in southern Taiwan. This unique variety is characterised by its sparsely appressed-pubescent leaflet abaxial surface, glabrous style, distinguishing it from M. macrocarpa var. macrocarpa. We also designate a lectotype of M. taiwaniana Y.C.Liu & C.H.Ou, and place the species in synonymy under M. membranacea Hayata, based on study of the lectotype and original description. These taxonomic and nomenclatural additions add to our understanding of the genus Mucuna in Asia.
