In O. pallidus the white flower-tube is almost as long as the calyx, whereas in O. rubicundus the white flower-tube is twice as long as the calyx.
In Orthosiphon pallidus, the corolla is as long as the calyx. The differentiating point between thymiflorous and rubicundus is leaf morphology. In rubicundus the leaf has very short petiole-up to 4mm or the leaf is almost sessile, and in thymiflorous petiole is longer-about 1 to 3cm;

I have updated eFI (efloraofindia) page on Orthosiphon (Pl. click).
Attempts have been made to incorporate most of the species available in India & nearby areas with details & keys directly or through links as far as possible. It’s quite possible that there may be some discrepancy in the accepted names & synonyms taken from other links.
Species discussed so far in efloraofindia are given at the bottom of the page in the form of links against Subpages. On clicking them one can see all the details.
If someone can provide complete list of Indian species with source references it will be wonderful.
Any comments/ corrections are welcome.

If you find any incorrect identification, pl. let us know. If anybody can send images of other species of this genera (for incorporation in the website), if any, it will be really nice.
Also, if anybody is interested to take up the activity of inserting images on efloraofindia pages from efloraofindia posts, pl. let us know.
