Lectotypification of Jatropha nana (Euphorbiaceae) with notes on its threats, and the status of Jatropha nana var. benghalensis

摘要

Jatropha nana is an endemic and threatened taxon with restricted distribution. A lectotype for this name is designated in the present communication. Jatropha nana var. benghalensis was recently described as a new variety based on stipule morphology and size of the root. On examining specimens from the type locality, these characters were found to be present but also variable. Hence, J. nana var. benghalensis is proposed now as a synonym of J. nana. A critical taxonomic treatment for this species is provided along with notes on anthropogenic threats to the species in and around the type locality.
