Thank you Vijayasankar ji. The key character of anther cells can not
be seen from pictures but I will look for that since I know both
plants distinctly. Rhinacanthus occurs in semi-evergreen habitats and
the other occurs in rocky dry hills. Pls look at the pictures posted
in a seperate post. Many pictures on net show a lot of confusion
between these 2 plants. So far I did not feel the need for a
microscopic study but I will now carry it when feasible. Regards,

> 1. Corolla white, no mention about purple spots on lip (corolla pale purple,

> 4. Upper lip 9.5 mm long; 2 mm broad at base and 1.3 mm broad at top (upper

> 5. Widely distributed & common (Rare, found in Konkan only?)
