Dear Gurcharan ji, *Senna uniflora* (Mill.) H.S.Irwin & Barne has several synonyms as per the plant list (http://www.theplantlist.org/tpl/record/ild-21536) and *Cassia sericea* is one among them. * * *C. sericea *has been mentioned in several flora books such as Flora of Coorg (Murthy & Yoganarasimhan, 1990), Flora of Udupi (Bhat, 2003) etc.
I too got this plant recently and photographed in detail from Bangalore. I shall upload them soon. I have identified my *specimen *by running the key as *C. sericea *and while checking the name in the plant list I found that this is *S. uniflora* now.
