Dinesh and others-- I know that most of the shrubby plants (and some of the trees) formerly in Cassia were shifted to Senna approximately 10-15 years ago. Some name changes involved simply swapping the genera names; others were not as direct as the example recently discussed. Most of the tree species in Senna have rather ill-smelling (when crushed) foliage; I believe all are yellow-flowered. Cassia may be pink, red, white, yellow. I'm not certain what other characteristics were used (perhaps DNA) to separate the two genera.
The GRIN listing is generally accepted as the standard for most genera here in the USA. Here is their listing for Senna: http://www.ars-grin.gov/cgi-bin/npgs/html/taxsearchlist.pl?select%20distinct%20}}||%20replace%28t.taxon,}%20f.%20},}%20f.%20}%29||}%20}||%20replace%28t.taxauthor,}%20f.},}%20ff.}%29||%20decode%28t.validtaxno,t.taxno,null,}%20%28=}||%20replace%28t1.taxon,}%20f.%20},}%20f.%20}%29||}%20}||%20t1.taxauthor||}%29}%29,%20t.taxno%20from%20prod.tax%20t,%20prod.tax%20t1%20where%20t.validtaxno%20=%20t1.taxno%20AND%20%28replace%28replace%28t.taxon,}%20x%20},}%20}%29,}-},}}%29%20like%20}senna^}%20or%20t.taxon%20like%20}senna^}%20or%20t.taxon%20like%20}x%20senna^}%20or%20t.taxon%20like%20}!senna^}...@%3cb%3egenus/species%3C/b%3E%20=%20%27%3Ci%3ESenna*%3C/i%3E%27%20&%20%3Cb%3Efamily%3C/b%3E%20=%20%27all%20families%27 And for Cassia: http://www.ars-grin.gov/cgi-bin/npgs/html/taxsearchlist.pl?select%20distinct%20}}||%20replace%28t.taxon,}%20f.%20},}%20f.%20}%29||}%20}||%20replace%28t.taxauthor,}%20f.},}%20ff.}%29||%20decode%28t.validtaxno,t.taxno,null,}%20%28=}||%20replace%28t1.taxon,}%20f.%20},}%20f.%20}%29||}%20}||%20t1.taxauthor||}%29}%29,%20t.taxno%20from%20prod.tax%20t,%20prod.tax%20t1%20where%20t.validtaxno%20=%20t1.taxno%20AND%20%28replace%28replace%28t.taxon,}%20x%20},}%20}%29,}-},}}%29%20like%20}cassia^}%20or%20t.taxon%20like%20}cassia^}%20or%20t.taxon%20like%20}x%20cassia^}%20or%20t.taxon%20like%20}!cassia^}...@%3cb%3egenus/species%3C/b%3E%20=%20%27%3Ci%3ECassia*%3C/i%3E%27%20&%20%3Cb%3Efamily%3C/b%3E%20=%20%27all%20families%27 These lists are not, however, complete, I believe. (I cannot locate, for example, Cassia angolensis, which I believe is considered valid.) Hopefully they will provide some use here.

Cassia ¿ species ? To: "Pardeshi S." <[email protected]> Cc: "indiantreepix" <[email protected]> Date: Thursday, September 3, 2009, 1:39 AM Many thanks, Satish ji, for validating the ID and providing its specifics. Current accepted name would be Senna surattensis (as Tabish has already pointed earlier in this thread). How do we follow current accepted names in India ? Is there any body in India which regulates / maintains such information and knowledge ? If there is, does it imply that there would be chance that a species is known by different names across the world, at any given time ? Please respond only at your leisure. Regards.
