Abstract

Cyphostemma annamalaii, a new species of Vitaceae, is described and illustrated from the tropical dry forests of southern Eastern Ghats, Tamil Nadu. The species is an herbaceous climber closely allied to Cyphostemma setosum, but can be easily distinguished by its leaves trifoliolate with elliptical in shape, apex obtuse-mucronate, base cordate-truncate, terminal leaflet is smaller than the lateral ones, stipules ovate-lanceolate, bracts and bracteoles are ovate, petals greenish-white that are reddish-brown on the upper half, and berries are yellow in colour. A detailed morphological description, a comparative table of allied species, colour photographs, a distribution map, and the species conservation status are provided.
