Please help me in identifying this shrub found in drier parts of Nilgiris. The height of plant was about 4 metre tall. Is this Euphorbia antiquorum?
Date: February 2010
Location: Nilgiris eastern slope, TN
Alt.: 250 m asl
Habitat: Dry scrub 

I still think that this is Euphorbia susan-holmesiae Binojk. & Gopalan.

Thanks for the lead …, this is getting interest.
