Abstract

Phlogacanthus sudhansusekharii, a new species is described here from the state of Arunachal Pradesh, India. This newly described species is closely allied to Phlogacanthus guttatus (Wall.) Nees, but can be differentiated by its strikingly different yellowish-cream colored corolla with yellow patches and brown maculation, ratio of calyx lobes and tube length being ~1:1 and deltoid staminodes (vs. greenish-cream to white corolla with red-maroon maculation, ratio of calyx lobes and tube length ~2:1 and subulate-ensiform staminodes in the latter).
