(Images by Mayur Nandikar & Muthu Karthick, (For more photos & complete details, click on the links))- Although C. pillosa is the traditional name that has been applied to this species, but I didn’t find extreme pilose leaf surfaces, it has very similar leaf surfaces like other Cyanotis speciesThis species is very close to C. adscendens, but C. adscendens is with fusiform tuberous root, few flowered inflorescence and plant of high elevation

Based on the various efloraindia discussion on Cyanotis species, some typical attributes which one could use for initial identification could be as below. I would appreciate if you could comment on this.

tuberosa : Stem, leaves, bracts hirsute, but leaf upper lamina glabrous, rossette leaves, stem leaves linear/lanceolate, condensed scorpioid cyme
cristata: Stem, leaves glabrous, condensed scorpiod cyme (also bracketed with C.cerifolia)
fasciculata : stem leaves puberulous, inflorescence: fasciculate (hence no crown like structure ??)
axillaris: solitary flower; in leaf axils, plant glabrous

Fwd: A Revision of the Genus Cyanotis D. Don (Commelinaceae) in India by Mayur D. Nandikar* and Rajaram V. Gurav : 10 posts by 9 authors. Attachments (1)- Revision of the Genus Cyanotis in India.pdf
I considered always eFlora as a platform to discuss about plant wealth and the diversity which we have in India and adjoining. I may not be active all the times but never forgot to respond whenever I felt that I am much sure about the ID. Generated database will definitely going be stand as a primary data source in Indian Floral history.

I am very fortunate to being part of this group. Recently one of my paper got published, and much of the discussion about the population and diversity of genus Cyanotis, including one photograph of Cyanotis arachnoidea are produced from our group discussion. Please find a copy of it, at initial stage Gurucharan Sir helps a lot to make MS flawless. Thank you all for the efforts which have been taken by group members, to achieve this height. Wishing you a very great year for eFlora family!


Congrats … for publishing this much-needed revision.


Congrats … We have been observing you partly during the process.


Congratulation for your efforts a good manuscript has been published.
The manuscript includes only 13 taxa when there are more than 16 species from India mostly from Southern part of India. Hope other taxonomy of other taxa will also be explored at an earliest


Thank you all for nice words, and off course as … rightly pointed out that all the group members are witnessed of this. Definitely this is possible due to the knowledge offered by group people, especially …, he has given the shape to MS while reviewing it.

…, though most of the Indian literature are enumerated more than 16 species with more than 30 binomials, we concluded that most of the species are merely ecotypes and therefore have been synonymised. Especially three groups are critically revisited viz. arachnoida, burmanniana and tubersoa. We tried to cite most of the binomials attached to the Indian Cyanotis,

I have updated eFI (efloraofindia) page on Cyanotis

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.

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.


.

1 or 2 species were done by …

.

Pl. go through Cyanotis (‎‎Commelinaceae) page with images of species (mainly 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.
