Summary
Herbarium-based studies of Mucuna lead us to make a new combination for a Hawaiian taxon. Mucuna persericea, formerly M. sloanei var. persericea, is an endangered species according to IUCN criteria. It is narrowly endemic to the island of Maui. With its recognition at the species level, we conclude that the genus is represented in Hawaii by three native species, plus several alien species, which are locally cultivated and potentially naturalised. We provide a key to aid in the identification of both the native and cultivated taxa.

Locality spelled ‘Keauae’ in publication, ‘Keanae’ on label. Kaenae is the correct spelling
