Dear Dinesh

The plant appears to be Euphorbia elegans Spreng.,endemic to Gujarat, Madhya Pradesh, Maharashtra, Karnataka, Orissa, Andhra Pradesh and Tamil Nadu. The distinguishing feature of the species is that the cyathia are partially or completely concealed inside the closely imbricate uppermost  leaves.

Dr. Balakrishnan, 

As I'm sure you're aware, E. pycnostegia also has imbricate upper leaves, as do the other members of sect. Elegantes.  Based on the glabrous internodes (flowering and lower), I am fairly certain this is E. pycnostegia var. zornioides.  In the first photo, a single fruit is also barely visible and it appears glabrous and obtusely lobed.  I am reading from The Genus (as per The Genus Euphorbia L. (Euphorbiaceae) in India a Taxonomic Revision but the information is supported by my own observations of the type specimens available on JSOR Plants and other online herbarium databases.

First couplet of the key to sect. Elegantes:

"1a. Plants glabrous; stems reddish brown; leaves whitish to pale green on lower surface; limbs of gland less than 1.2 mm across, almost entire..................................................................E. pycnostegia

1b. Plants pubescent or hairy; stems pale brown or grey; leaves green or pale green on lower surface; limbs of glands more than 1.5 mm across, sinuous or palmately lobed.................2"

Nathan Taylor
