Abstract
Strobilanthes lawsonii was described by Gamble based on four gatherings collected from different parts of the Western Ghats. However, the gatherings cited in the protologue represent three different species. Carine et al. identified them to be S. lawsonii, S. gamblei and S. pushpangadanii. However, the specimen identified as S. pushpangadanii and many specimens collected from various parts of Kerala and Karnataka as S. gamblei by them represent a new species, S. bourdillonii. An updated description is provided for Strobilanthes gamblei.
