304 NATURAL IIISTORY OF PLANTS. 



both ends, finally separating. Seeds ovate ; hilum lateral.— A shrub ; 

 leaves alternate simple j 1 petiole short, articulated at base ; stipules 

 short triangular persistent ; flowers in axillary racemes, each flower 

 solitary in axil of a short bract, shortty pedicellate ; bractlets 2 

 (Mascarene Islands 3 ). 



145. Coronilla L. 4 — Receptacle cupuliform, glandular within. Calyx 

 gamosepalous ; teeth 5, nearly equal or 2 superior shorter or con- 

 nate to a greater height. Petals rather long unguiculate • standard 

 suborbiculate reflexed ; claw furnished with a simple or double rather 

 projecting appendage within and slightly above base ; wings obliquely 

 obovate or oblong, claws thin; keel curved, beaked. Stamens 1C, 2- 

 adelphous, 9 connate into a sheath cleft above ; vexillary stamen 

 free ; filaments free at apex, all or 5 alternate dilated above ; anthers 

 nearly or quite uniform. Germen sessile cc-ovulate; style inflexed 

 subulate glabrous; stigma minute capitate. Legume terete, 4-gonous, 

 or slightly compressed, straight or arched ; segments oblong or 

 elongated, almost without veins. Seeds transverse oblong exarillate. 

 — Shrubs or herbs, glabrous or silky ; leaves imparipinnate ; leaflets 

 co, or more rarely 3, quite entire ; stipules of variable form, more 

 or less adnate to petiole ; flowers 5 in cc- or few-flowered long-pedun- 

 culate axillary umbels ; bracts small. {Europe, iccstern Asia, northern 

 regions and western Islands of Africa''). 



146. Ornithopus L. r — Calyx broadly tubular or subcampanulate ; 

 lobes 5, long, nearly equal or 2 superior connate to a greater height. 

 Petals almost those of Coronilla, shorter ; keel nearly straight obtuse, 

 shorter than wings or very short. Stamens 10, 2-adelphous (9-1);
