I have updated eFI (efloraofindia) pages on Desmodium, Codariocalyx, Dendrolobium, Dicerma, Hylodesmum, Phyllodium & Tadehagi

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.
