1982] CASSIINAE—SENNA 81<br />
technicaUy synonymous with S. occidentalis (Linnaeus) Link. WhUe the epithet<br />
surattensis must be ado<strong>pt</strong>ed for the species known latterly as Cassia suffruticosa,<br />
the earliest epithet avaUable and legitimate in Senna for the related, large-flow<br />
ered species is apparently sulfurea. Cassia discolor Desvaux, which has a short<br />
priority over C. sulfurea, has been considered a synonym (Bentham, 1871), but<br />
is based on a mixture of fohage of 5. pallida and mismatched fruit of S. sulfurea,<br />
and herein is typified by the "discolorous" fohar element ofthe typus. The true<br />
identity of C. surattensis was first appreciated, according to annotation of the<br />
holotypus at Geneva, by Drs. K. and S. Larsen in 1978.<br />
2. Senna surattensis (N. L. Burman) Irwin & Barneby, comb. nov. Cassia su<br />
rattensis N. L. Burman, Fl. Indica 97. 1768—"Senna surattensis Garzin<br />
[=Laurent Garcin] herb."—Holotypus, originaUy labelled 'Cassia<br />
sumatrensis' but the epithet corrected in an old hand to 'surattensis,'<br />
G (hb. Burman. annotated as typus by K. Larsen, 1978)!—Wrongly<br />
equated by Colladon, 1816, p. 105, with Cassia auriculata, and by<br />
DeCandoUe, 1825, p. 495, with C. glauca and illegitimately reduced<br />
to it; restored by MerriU, Philip. J. Sci. 19: <strong>35</strong>3. 1921 but wrongly<br />
apphed by De Wit, 1955, p. 269 and consequently by several modern<br />
writers, to our S. sulfurea.<br />
Cassia fastigiata Vahl, Symb. Bot. 3: 57. 1794.—"Habitat in India orientah. KONIG."—Caret<br />
in hb. Vahl., C!, but the protologue decisive and referred by Vahl himself (ms., C) to Cassia<br />
glauca.—Listed by Bentham among many synonyms of Cassia glauca, this name was overlooked<br />
by De Wit, 1955.<br />
Cassia suffruticosa Roth, Nov. sp. pl. 213. 1821.—". . . communicavit celeber HEYNE ex India<br />
Orientah."—Collected presumably by Konig, no typus found, but the protologue decisive.<br />

Like closely related S. sulfurea exce<strong>pt</strong> for more numerous, smaUer lfts, smaUer<br />

always the dorsal face of lfts pUosulous with ascending or subappresed, often<br />
