I have updated eFI (efloraofindia) page on Pterospermum
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.
Any comments/ corrections are welcome.
I have added list of all species of Pterospermum in India as per the Flora of India Vol-3 …... Please see, and if useful, retain.
I have further updated it based on BSI Flora of India with details & keys (Volume 3- 1993)

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, or can identify unidentified images, it will be really nice.
