Many thanks for the detail information from you and Sing ji A.porphyristachya has been named as a var. of A aspera in Mah BSI flora. withe description of leaves similar to what you have described for the above species.i.e glabrous mambranous as against thick velvetty tomentose in A.aspera. but......as you have described ; pattern of staminodes must be the key for distinguishing amongst the two. (Of course apart from the geographical distribution.) Dr Satish Phadke
