Kindly examine and identify this plant.. 


Habitat:Wild,on wet moss-clad rocks amidst grass in montane forest 

Sighting:Mullaianagiri,Chikmagalur,Karnataka about 1700 msl 

Date:15-09-2015 and 09-10-2016 

Very nice images again, not sure but can be Swertia sp.

Swertia species with images in eFloraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ Biotik/ efloras/ books etc., where ever available on net) 

Could not find any match with comparative images in efi at Swertia

May be a new addition to efi ?

Its a member of Rubiaceae. Some genus related to Hedyotis, Oldenalandia

The images show some characteristic features of Rubiaceae including the bifid stigma and persistent calyx in fruit. I remember … posting a similar plant 2 years back from the same area, around the same time. A late blooming herb towards the end of monsoon in the grasslands.
Swertia would have nectaries/glands present at the base of the inner face of petals which are clearly lacking here.

I think close to Hedyotis cyanantha Kurz as per images herein.

This is a very small herb found growing on a rock at higher altitudes (approx. 5500ft) in Mullayanagiri region (Karnataka)
Flowers were small in size, approx. 3mm across.

Date/Time: 26-01-2014 / 15:10Hrs
Plant habit: Herb, leaves were not seen.

Perhaps a member of Gentianaceae

good finding. more details about the leaves and so….??…

I think Hedyotis cyanantha ..

It seems to be Neanotis foetida (Dalzell) W.H.Lewis according to flora Hassan dt.

I think more closer to images at Hedyotis cyanantha from near Mullayaiamgiri in Karnataka-GSOCT02/13 by … rather than Neanotis subtilis (syn: Neanotis foetida)
