I agree with Neil ji's id: *Sida retusa* (the accepted name, however, is *Sida alnifolia*). As assured by Rashmi ji, I think all the pictures are of the same plant, too (due to similar stem color, indumentum, and the lower typically-retuse leaves can be seen in the backdrop of the first picture). A picture of whole plant may be helpful.
It is not uncommon to see variations in leaf shape and size even in the same plant here. The upper younger leaves usually narrower with pointed tips whereas the lower leaves characteristically broad and wedge-shaped or triangular with retuse / notched tip. This is clearly seen in one of Dinesh ji's pics: http://www.flickr.com/photos/dinesh_valke/7980262837/ Pl also see: https://groups.google.com/forum/?hl=en&fromgroups=#!topic/indiantreepix/fqs48KRMsU4 Regards Vijayasankar Raman National Center for Natural Products Research University of Mississippi On Thu, Oct 11, 2012 at 1:57 AM, Nidhan Singh <nidhansingh...@gmail.com>wrote: > I am also of the opinion that all pics do not belong to same plant they of > course have resemblance...but the first image *rk_for-id_001_1.jpg *and > third picture *rk_for-id_001_3.jpg *are of same plant, rest are distinct.. > > > -- > Regards, > > Dr. Nidhan Singh > Assisstant Professor > Department of Botany > I.B.
