Cayratia (Vitaceae) :  3 posts by 2 authors.

I have updated eFI (efloraofindia) page on Cayratia (Pl. click).

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.


I have added the list of Indian species.


.

I searched on internet and some books what Cayratia stands for. 
Just could not get the meaning other than a observation that it could be based on a vernacular name from India.

Latin Cayratia, from the Annamese vernacular name, cay-rat, a vine … National Parks Board, Singapore
Many thanks to … in facebook.


.

Pl. go throughCayratia‎‎ ‎(Vitaceae) page with images of species in efloraofindia.

I request you to pl. go through & point out mistakes, if any. I hope this will aid in identifications in future. 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.
