21. Cassia MIssIssIPPIENSIS n. sp. 
Low, branching, suffruticose,; stem terete, glabrous; leaves — 
subcoriaceous, pubescent, 8—14-foliolate; leaflets small, elliptical or 
obovate, mucronate, basally asymmetrical, 5 cm. long, .I-.15 cm. 
wide ; secondary nerves 3 or 4, opposite, rarely alternate ; petiolar 
gland minute, cupuliform, sessile, situated midway between lower- 
most pair of leaflets and base of rhachis; stipules acutely linear, 
membranaceous, persistent; peduncles 1 cm. long, axillary, 
I-flowered ; flower large (petals 1 cm. long, .3 cm. wide); anthers 
10, rostrate, all perfect, the lower 5 larger, yellow, the upper 
smaller and reddish; anther-sacs dehiscent by terminal pores; 
sepals lance-linear, slightly pubescent, not surpassing the petals; 
legume turgid, linear, sparsely pubescent, ventrally and dorsally 
dehiscent, elastic; length 2.5 cm., width .4 cm.; seeds 4 or 5, 
ovoid, rather large (longest diam. 3 mm.) transverse. 
Type in herbarium of Columbia College, collected by Miss K. 
Skeehan, 1889, at Ocean Springs, Mississippi. 
The specific characters are well-marked, the only Cassia to 
which it bears any resemblance being C. pygm@a D.C., a Cuban 
Species, and not reported, so far as I know, from any of the States. 
C: pygmea may be distinguished by its dense hirsute pubescence, 
Its oblique seeds and fewer pinne on the rhachis. The two 
plants in general external appearance are quite similar.
