266 NATURAL HISTORY OF PLANTS. 



72a. Poissonia H. Bn. 1 — Mowers irregular resupinate. Eecep- 

 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 ; sestivation 

 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 co ; 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, cc-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 (Peru 9 ). 



73. Cracca Benth. 3 — Eeceptacle 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 co-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 4 in axillary racemes ; bracts setaceous 1 -flowered ; bractlets 

 {Tropical and Central America*).
