282 NATURAL HISTORY OF PLANTS. 
exarillate-—Annual or often perennial herbs, sprinkled with glan- 
dular dots; leaves imparipinnate exstipellate; stipules setaceous ; 
flowers in heads or oftener in spikes ; inflorescences terminal or leaf- 
opposed ; peduncles usually long; bracts narrow setaceous or broad 
membranous, imbricated ; bractlets 0 (Hot regions of North America’). 
101. Eysenhardtia H. B. K.2—Flowers almost those of Dalea ; 
calyx nearly equally 5-toothed. Petals nearly equal in length, long- 
unguiculate ; standard subobovate ; wings and petals of keel narrower, 
nearly similar to each other. Stamens 10, 2-adelphous (9-1); anthers 
uniform. Germen subsessile (of Dalea); style hooked at apex with 
introrse oblique stigmatiferous summit, or minutely capitate and 
geniculate below apex, the joint furnished with an anterior gland at 
base. Legume small oblong-falcate, not included, rather compressed, 
indehiscent (?). Seeds 1, 2, oblong-reniform.—Shrubs, sometimes 
spinous, sprinkled with glandular dots; leaves imparipinnate ; leaf- 
lets oo, minutely stipellate; stipules small subulate ; flowers*® race- 
mose; racemes terminal, simple or branched bearing leaves at base; 
pedicels very short; bracts and bractlets narrow caducous (South- 
western North America‘). 
102. Amorpha L.'—Calyx gamosepalous to a considerable height ; 
teeth or lobes very nearly equal or lower ones longer; estivation 
imbricated, often finally subvalvate. Petal 1, vexillary, obovate 
erect unguiculate; limb protecting reproductive organs. Stamens 
10, connate at base into a sheath cleft above, higher free; alternipe- 
talous stamens longer; anthers uniform. Germen sessile; ovules 2, 
descending ; style curved, glabrous or villous; stigma small terminal. 
_ Legume short oblong, lunulate or falcate, indehiscent. Seeds 1, 2.— 
Shrubs or undershrubs, glabrous or pubescent and sprinkled with 
minute glandular dots; leaves alternate imparipinnate; leaflets 
numerous; stipels usually setaceous, very caducous; stipules
