I have updated eFI (efloraofindia) page on Salacia

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 databases/ books.

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 are welcome.

I have added the list of Indian species of Salacia as per Flora of India vol-5.
Thanks a lot, ..., Most of the species at other links match except for the following: 
Forest Plants of Eastern India By Amal Bhusan Chaudhuri (1993)- Brief details-
As per JSTOR, Salacia roxburghii Wall. is an accepted name with S. salacioides (Roxb.) Rolla Rao & Hemadri as a syn. (may or may not be correct but it is linked now). 
S. macrophylla Blume, synonym S. flavescens Kurz and S. ovalis M. Laws. (Konkan and the Andamans) 
As per Genetic Resources of Tropical CropsSalacia macrophylla Blume (syn. Salacia flavescens) also sorts out the mystery of Salacia flavescens Kurz
