Rediscovery and notes on Brachystelma maculatum (Apocynaceae)

Abstract

Brachystelma maculatum Hook.f. was rediscovered far from the type locality after a century in Nallamala forests of Andhra Pradesh. Its taxonomic identity and morphological affinity with B. bourneae, B. rangacharii and B. nallamalayanum are discussed. An enhanced description of B. maculatum, its conservation status and an updated key to delineate the above species are presented.
