Chaetocalyx is a genus of lianas in the legume family, Fabaceae. It belongs to the subfamily Faboideae, and was recently assigned to the informal monophyletic Adesmia clade of the Dalbergieae. Members of this genus are found in Central and South America.[4] Chaetoealyx can be distinguished from most other legumes by its climbing habit, its imparipinnate leaves, and, in most species, by its elongate loments. It can be distinguished from Nissolia, which also has a climbing habit, by the articles of the loments, which are uniform in size in Chaetocalyx, rather than with a terminal, expanded, winglike article as in Nissolia.[3] Unlike most papilionoid legumes, Chaetocalyx species do not form root nodules.[5]
