Name confusions in Indian Cycads : 3 posts by 2 authors. Attachments (1) – Name confusions in Indian Cycads.pdf- 300 kb.
I came across the attached publication on the above subject which clarifies some of the confusions in the Indian Cycads. This paper appears to be a very valuable contribution.

Thanks, … I have gone through it. Very interesting.

However, the last Paragraph of the paper has been presented in very aggressive mode which is not desirable. One should maintain minimum ethics while presenting a paper. The authors possibly forgot their own misgivings. They described a new species in 2015 (Nordic Journal of Botany 33: 38. 2015) which got merged in the same year (Journal of Economic & Taxonomic Botany 39: 556. 2015).

I have updated eFI (efloraofindia) page on Cycas

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.

Any comments are welcome.

.

Pl. go through ‎Cycas (‎‎Cycadaceae) page with images of species (done by …) in efloraofindia.

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.

Also, if anybody is interested to take up the activity of inserting images on efloraofindia pages from efloraofindia posts, pl. let us know.
