Re: Name changes?

Many Cassia species were transferred to the genera Senna and Chamaecrista
in a large monograph by Irwin & Barneby in the journal "Memoirs of the New
York Botanical Garden" vol. 35 (1982). Some species did remain in Cassia,
however. Senecio is such a huge genus that botanists have been trying to
carve it up for decades (Cineraria, Kleinia, Tephroseris, etc., etc.) A
good site to look up names (but not cultivars) is Missouri Botanical
Garden's TROPICOS database. It will give you synonyms and accepted
current names (although what is "accepted" is always open to argument 
among taxonomists, of course!)
