The genusAlysicarpus Desv. (Fabacaeae)
is represented by 25Ð30 species distributed in the tropical and
sub-tropical parts of the old world (Ohashi et al.
1981) and occurs abundantly in the dry zones of Maharashtra, Andhra Pradesh, Gujarat and Karnataka states of India, with 15 species and
seven varieties (Pokle 1999).
Alysicarpus naikianus Pokleis an endemic species described in 1999, and until recently was only known from
a few collections from three localities, namely, Appachiwadi,Kakti and ShivajiUniversity Kolhapur campus, Maharashtra (Image 1, Fig. 1). In recent surveys, a number of
additional populations were found in western India in addition to the type
localities. They are now known to be chiefly distributed along the eastern
escarpments of the Western Ghats and the coastal plains of Kerala, Karnataka,
Goa, Maharashtra and Gujarat.

Ecological note: The
species is found along road sides, on grazing grounds, in open, dry and waste
places especially in western India along with Alysicarpus bupleurifolius (L.) DC. and A. tetragonolobus Edgew. Previously, it was considered to be a rare and endemic taxon, however, intensive collections clearly indicate thatthe speciesis common, widespread and fairly abundant.
