I have updated eFI (efloraofindia) page on Aconogonon, Bistorta, Fagopyrum, Fallopia, Koenigia, Persicaria, Polygonum & Rubrivena

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.

In my opinion most of the above genera should be treated under Polygonum sensu lato.  I am working on Indian Polygonaceae but it needs thorough field work. The taxonomic complexes are to be solved with the help of SEM/Molecular studies. I have listed all Indian species but it is not yet published.
