Nayan ji, your wild guess was correct in one sense. Cassia glauca Lam. and C. surattensis Burm.f. are both synonyms of now correctly known Senna surattensis (Burm.f.) Irwin & Barneby. At the finer level true surattensis with larger (2-4 inches) leafets in 4-6 pairs, pods 6-8 inches long and known as Senna surattensis (Burm.f.) Irwin & Barneby subsp. surattensis, whereas C. glauca Lam. (C. glauca var. suffruticosa Koenig in Flora of British India) with 6-9 pair of smaller leaflets (1-2 inches) and smaller pods (3-4 inches. is Senna surattensis (Burm.f.) Irwin & Barneby subsp. sulphurea (DC. ex Collad) Randell.
And now an interesting one. C. glauca Lam. was published in 1789, whereas C. surattensis Burm.f. in 1768, and hence latter gets priority when two are treated as same species. At subspecies level, true surattensis is subsp. surattensis (no authority, as it is automatically created name if we treat C. glauca as distinct subspecies-it is autonym). and now you will ask why not to use subsp. glauca as name. Well Cassia glauca Lam, 1789 and C. sulphurea DC. ex Collad., 1816 are synonyms, and hence former is prefered, but when transferred to genus Senna (all 10 stamens perfect) Senna glauca Roxb., is already used for a different species, and sulphurea gets preference. I hope it was not very boring. .

Cassia ¿ species ? Gurcharan ji yesterday i id it as Cassia glauca, but some how it is missing in the thread, what do you think about my this wild guess? thanks N.S.Dungriyal IFS Chief Conservator of Forests and Field Director Satpura Tiger Reserve Hoshangabad M.P. 09424792100 ------------------------------------------------------------------------------ From: Gurcharan Singh <[email protected]> To: Yazdy Palia <[email protected]>; Kenneth Greby <[email protected]> Cc: Indian Tree Pix <[email protected]>; Dinesh Valke <[email protected]> Sent: Thursday, 3 September, 2009 12:19:53 AM Subject: [indiantreepix:17454] Re: ... Cassia ¿ species ? Not Cassia fistula atleast which has distinctive cylindrical long pods. This one seems more probably C. surratensis, the only thing that looks different to me is the thin long stalk of pod. The specimens in our garden don't have such long stalks. Leaves and flowers resemble.
