266 NATURAL HISTORY OF PLANTS. 
72a. Poissonia H. By.\—Flowers irregular resupinate. Recep- 
tacle obconical turbinate, lined by a rather thick disk. Calyx 
gamosepalous subcampanulate, deeply 5-lobed; lobes long subulate 
subequal; 2 posterior connate to a considerable distance ; estivation 
imbricated. Petals unguiculate; standard suborbicular; wings 
obliquely obovate ; keel curved, rather obtuse. Stamens 10, 2-adel- 
phous (9-1); anthers uniform. Germen very shortly stipitate; 
ovules ©; style curved, covered below stigma with thick hairs 
forming a short pyriform mass, glabrous elsewhere; apex capitate 
stigmatiferous. Legume shortly stipitate, surrounded at base by 
persistent calyx, linear, acute at both ends, compressed, depressed 
in oblique furrows between seeds outside, opposite surfaces almost 
meeting within, o-locellate. Seeds transversely obovate, compressed 
glabrous ; funicle short; embryo exalbuminous; radicle elongated, 
much inflexed—An undershrub (?), hoary tomentose in every part ; 
leaves alternate petiolate 1-foliolate; leaflets obovate penniveined, 
articulated at base; stipules linear subulate, flowers axillary solitary; 
peduncle reflexed after anthesis (Perw’). 
73. Cracca Bunrn.’—Receptacle shortly obconical, lined by a 
disk, often coloured. Calyx gamosepalous membranous; lobes 5, 
nearly equal, setaceous acuminate at apex. Petals about equal in 
length; standard orbicular or reniform; sides reflexed; wings 
unequally obovate or oblong, free; keel broad curved, acute or 
subrostrate at apex. Stamens 10, 2-adelphous (9-1). Germen sub- 
sessile «-ovulate ; style rigid thin curved, above and within longi- 
tudinally (often thinly) bearded; apex minutely capitate, stigma- 
tiferous. Legume linear compressed rigid, transversely septate 
within and transversely constricted by lines outside between seeds, 
2-valved. Seeds unevenly orbicular or nearly square, exarillate ; 
embryo fleshy; radicle elongated, much inflexed.—Herbs or under- 
shrubs (?); leaves imparipinnate stipellate; stipules setaceous ; 
flowers’ in axillary racemes ; bracts setaceous 1-flowered ; bractlets 0 
(Tropical and Central America’).
