Sorry Satish ji Some mix up in formatting earlier. here is correct form Dear Satish ji Thanks for your conclusion, but I would like you to consider a few things before taking a final decision. I have not seen this plant in nature myself but judging from the available information, I fear it never has 4 leaflets, not to say of 2 leaflets that you write. Senna uniflora is an American weed, and only recently introduced in India (Not reported in FBI), and we can't expect it to undergo drastic changes in India over a short period of time. >From all sources of information the species usually has 4 pairs of leaflets (and not 4 leaflets) though the number may varry from 3-5 pairs. Some identifications get fixed in mind and difficult to forget. My colleagues would fight with me when I would tell them spinach they are using in their practicals is not Spinaceae oleracea, rather leafy vegetable a variety of Beta vulgaris. It took me more than 10 years to make them understand when they gave this plant in taxonomy classes. The description of two is poles apart.
I request you to kindly go through the attached paper, study the plants and then decide. http://nopr.niscair.res.in/bitstream/123456789/6352/1/NPR%208(5)%20525-527.pdf I am not saying that this is Senna absus, but just for infrmation S. absus is a species long established in India, has four leaflets and also a gland between the leaflets. Senna unflora has been introduced in in many places in India including Pune, Karanataka and other places, and you and other members may soon find specimens with true S. uniflora characters. -- Dr. Gurcharan Singh Retired Associate Professor SGTB Khalsa College, University of Delhi, Delhi-110007 Res: 932 Anand Kunj, Vikas Puri, New Delhi-110018.
