Dear friends ... this plant had earlier got mixed up with
Sida cordata at
https://groups.google.com/d/topic/indiantreepix/xUcJzKelIZE/discussion.
Many thanks to Vijayasankar ji for having pointed it out.
At eflora of China, a small note on the page of
Sida mysorensis [
http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200013762 ] :
Sida mysorensis is often confused with the closely related species S. javensis Cavanilles and S. cordata (N. L. Burman) Borssum Waalkes but can usually be distinguished by the presence of glandular hairs and the erect habit.
This notable "erect habit" of
S. mysorensis made me go look up for the habit of S. cordata which turns out to be procumbent (or rarely ascending up to 1 m)
This difference is quite worthy other than clear key clarified by Vijayasankar ji ... of branched inflorescence for
S. mysorensis, whereas, flowers in
S. cordata are solitary.
Regards.
