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.

Thanks a lot, …
I have taken GRIN as the basis as it relied on the latest litrature published in 2011 or 2012. Other efloras & The Plant List etc. has also been considered where ever a taxa is not available in GRIN.
As & when new findings are published it can be updated again.

Bistorta page with comparative images:
Pl. go through Bistorta (Polygonaceae) page with comparative images of species in efloraofindia. On clicking the link of species, one can check the complete details. Genus pages generally give details of most of the species found in India.
I request you to pl. go through & point out mistakes, if any. I hope this will aid in identification in future. If anybody can send images of other species of this genus (for incorporation in the website), if any, or can identify unidentified images, it will be really nice.
