Dear friends ... this plant had earlier got mixed up with Sida cordata
Many thanks to Vijayasankar ji for having pointed it out.
At eflora of China, a small note on the page of Sida mysorensis
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 difference is quite worthy other than clear key clarified by Vijayasankar ji ... of branched inflorescence for S. mysorensis
