Cascaronia astragalina is a species of flowering plant in the legume family, Fabaceae. It is the only member of the genus Cascaronia.[1] It is a spindly shrub or multi-stemmed tree native to southern Bolivia and northwestern Argentina. It grows in seasonally-dry subtropical forests, at forest margins and along rivers.[2]
Cascaronia belongs to the subfamily Faboideae, and was recently assigned to the informal monophyletic Pterocarpus clade of the Dalbergieae.
