Thanks Gurcharan ji for posting your plant. I find many similarities among our plants. I see your plant leaves show to a fair extent dentate margin, and "the blade rugose" just as described in the document you have linked. Plant in my post <https://groups.google.com/d/msg/indiantreepix/m_su9auOfwU/sFUynIEYBwAJ> matches quite well with yours, except for the leaf margin which comparatively seems to have blunt serration, which could be depending on various factors.
It is worth heeding to a line in the last block of content with heading: Comparison of S. jamaicensis and S. cayennensis ... quoting: The species are *variable* and *readily hybridize*, often making > identification difficult. Thus what we have sighted could be an hybrid resulting in not much toothed leaf margin and white flowers. Regards. Dinesh On Mon, Dec 12, 2016 at 9:31 AM, J.M.
