Dear Sir, Thank you very much for the response. I referred Cooke's flora to know more about these plants. The following points of him for *Rhinacanthus nasutus* are matching with the plant posted here**. (Cooke's descriptions for *Hypoestes lanata* are given in parenthesis, in red font): 1. Corolla white, no mention about purple spots on lip (corolla pale purple, lower lip spotted with dark purple at the base) 2. Upper lip linear-oblong, twisted or recurved (upper lip is understandably erect...as there is no mention about this) 3. Upper lip much shorter than the lower (upper lip more or less equal to the lower) 4. Upper lip 9.5 mm long; 2 mm broad at base and 1.3 mm broad at top (upper lip 15.8 mm by 3.2 mm, so it is much longer and broader here, in Hypoestes) 5. Widely distributed & common (Rare, found in Konkan only?)
I also learn that the anthers are *2-celled in Rhinacanthus*, and are *1-celled in Hypoestes*. May be this feature will help to fix the id unambiguously. And the bracts said to be larger than calyx segments in Hypoestes, which is not the case in the posted picture (clearly seen in pic # DSC_1483e). The plant posted here by Raghu ji looks entirely different from either of the pictures in the link: https://groups.google.com/group/indiantreepix/browse_thread/thread/fb4a215ceb4240ae?hl=en# Please correct me if I am wrong.
