Cassia. LEGUMINOSiE. 393 



§ 1. Segments of the calyx equal, rather persistent : petals subscssile ; the vp- 

 per one broadest and glandular at the base : filaments somewhat glandular- 

 hairy below : one of the anthers imperfect: ovary glabrous: stigma tenni' 

 nal, tubular : legume ovate- oblong, about 2-scedcd : glands pedicellate. — 

 Hoffiiianseggiaria. 



1. H. Drummondii: glabrous, wiili a fow scattered pedicellate glands; 

 stem diffuse, sulVrutescent; jjinmc 3 (liigitale), abru|)tly8-12-foIiolate ; leaflets 

 elliptical, obtuse orretuse; Icgunics luiiatL'-ovale, glabrous. 



Texas, Drummond ! — Pbiiit low and nuicli branclied, with a very few 

 subulate scarcely capitate glands on the lower side of tlie petioles, or on the 

 lower surface or ajjcx of the leaflets, the ju'dicels, margin of the calyx (^cc., 

 rarely on the branches. Leaves small. — Upi)er petal with rcddisli spots.— 

 AVe have not observed the stipules : tlie seeds have also tallen lidiu the pods 

 in our specimens ; but there are about 5 ovules. In some flowers, we observe 

 that the alternate filaments are almost filiform and nearly glabrous ; while 

 those ojjposite the sepals are thickened and clothed with thick glandular 

 hciirs ; but in others tliey are all nearly similar. 



§ 2. Segments of lite calyx {equal ex Cav., or the loicer one much broader and 

 carinate-concave) at length deciduous from Hie persistent base : petals not 

 glandular at the base, the superior one smallest : filaments declined, hairy 

 below, all fertile : ovary clothed tcith stellate scales or hairs : stigma lateral 

 and someichat hooded : legume ovate or oblong, 2-3-seeded : glands de- 

 pressed. — Pomaria, Cav. (Character from the N. American species.) 



2. H. Jamesii : canescently pubescent ; stipules subulate, entire ; pinna; 5 

 (2 pairs and a terminal one), abruptly 10-16 foliolate; legume broadly ob- 

 long, somewhat lunate ; leaves, calyx, petals, and legmiies sprinkled with 

 sessile black glands. — Pomaria glandulosa, Torr. ! in arm. lye. New York, 2. 

 p. 193, not of Cav. 



Sources of the Canadian River, Dr. James ! — A low much branched 

 shrubby plant. Leaves with the 3 u])per ])iini;e arising from the same jioint. 

 Leaflets oval, obtuse at botli ends, nearly glabrous above. Racemes elon- 

 gated, op])osite the leaves. Flowers nodding or reflexed, rather large. Calyx 

 a little oljlicjue ; the 4 upper segments lanceolate, acute ; all membranaceous. 

 Upper petal marked with reddish spots. Style subulate, dilated above and 

 somewliat gibbous at the apex ; the stigma turned to the ujjper side, and 

 somewhat hooded, the membranaceous upper portion of the style being slit 

 for some distance on that side. Legumes about an inch long, scabrous, 

 sprinkled witli glands, flat, 2-3-seeded. Seeds broadly oval, compressed. 



55. CASSIA. Linn. ; Lam. ill. t. 382 ; Vogcl, syn. gen. Cass. (1837.) 



Sepals slightly united at the base, mostly a little unecpial, deciduous. 

 Petals 5, unequal. Stamens 10, often unequal, the three upper commonly 

 abortive, the 5 alternate ones rarely wanting : anthers dehiscent at the apex, 

 or sometimes by a foramen at the base. Legume terete or compressed, 

 woody, coriaceous or membranaceous, 1-celled, or many-celled by trans- 

 verse partitions, which are sometimes filled with pulp. Seeds anatropous, 

 ■with a straight embryo, surrounded with a small ([uantity of albumen. —
