I have updated eFI (efloraofindia) page on Carduus
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.
I have added the list of species known in India based on Karthikeyan et al. 2009
Thanks a lot, …. It will be interesting to know where Kashmir, Uttarakhand & Ooty plant posted by … & others (see Carduus onopordioides) has been placed by Karthikeyan et al. 2009.
Thanks, … I think … was looking for such references to settle the issue in Asteraceae Fortnight Part 2-Discoid heads: Carduus in Kashmir….onopordioides…….edelbergii…….pycnocephalus-GS2
Attaching 4 pages of Flora of India in this matter. May be found useful.
Thanks … I will go with C. edelbergii.

If you find any mis-identification, pl. let us know. If anybody can send images of other species of this genera (for incorporation in the website), if any, it will be really nice.
