Mucuna imbricata DC. ex Baker, J. D. Hooker, Fl. Brit. India 2:185. 1876 (DC., Prodr. 2:406. 1825, nom. nud.);

Ohashi (1979) treats this species as a synonym of Mucuna nigricans and Tateishi and Ohashi (1981) give Mucuna imbricata and M. nigricans as synonyms of M. hainanensis. Wilmot-Dear (1991) suggests that five possible taxa may be involved in delimitation of these species. This assessment is based on the treatment of this species in the revision of Mucuna by Wilmot-Dear (1987). Wilmot-Dear (1987) also notes that this species closely resembles M. interrupta Gagnep. 
This species is listed as occurrring in Bhutan, northeast India, Bangladesh, Myanmar and Sri Lanka (Wilmot-Dear 1987). It is also listed by Parkinson (1923) as a component of the forest flora of the Andaman Islands, however, this is not confimed by Wilmot-Dear (1987). The specimen from Sri Lanka has now been redetermined as M. atropurpurea (Thomas pers. comm. 2011). 
This large woody climber is found in river valleys, forests and woodland margins. Stinging hairs on the fruits provide protection from predation (Sanjappa pers comm. 2011).
