Ardisia : 1 post by 1 author.

I have updated eFI (efloraofindia) page on Ardisia

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

Ardisia‎‎ with comparative images:
Pl. go through‎ Ardisia‎‎ (Primulaceae) 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.
