Exacum tenue (Gentianaceae): A new record for India A.K. Biswal, N.C. Rout1*, N.K. Dhal1 and M.V. Nair2. Rheedea Vol. 21(2) 174-176 2011.
Abstract- Cotylanthera Blume (Exacum L.) is a less known genus in India found mostly in Himalayas (1000 – 2000 m). The rarity of the taxon is reflected from its non-representation in Indian Herbaria including CAL. The genus has confused taxonomists since its discovery till it was found to be nested in genus Exacum L. (Gentianaceae) in early part of this century. There are only four saprophytic and achlorophyllous species reported for the genus from Old World. Exacum tenue (Blume) Klack. is reported here as a new report for Indian Gentianaceae from Similipal, Odisha. Its occurrence in a geographically isolated region from its earlier reported localities is of ecological and phytogeographical significance.

I have updated eFI (efloraofindia) page on Exacum

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.


 

Pl. go through Exacum (‎‎‎‎‎‎‎‎‎‎‎Gentianaceae‎) page with images of species in efloraofindia.

If you find any incorrect identification, pl. let us know. 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.
