306 NATURAL HISTORY OF PLANTS. 
culate or muricated; either indehiscent jointed, or nearly continuous 
(joints scarcely marked). Seeds ovate or transversely oblong, exaril- 
late ; hilum lateral; embryo fleshy; cotyledons contorted folded. 
—Herbs, almost stemless or decumbent; leaves alternate simple, 
tapering for a considerable distance at base into petiole; stipules 2, 
lateral, adnate to petiole; flowers' nutant, solitary or few subum- 
bellate; peduncles subaxillary, each with a bud; bracts minute ; 
bractlets 0 (Southern Europe, western Asia, northern Africa’). 
149. Hippocrepis L.'—Receptacle shortly obconical, lined by a 
disk. Calyx gamosepalous, usually membranous; teeth 5, nearly 
equal or 2 superior connate toa variable height. Petals long-ungui- 
culate ; standard suborbicular; claw at base rather thick and terete 
or subappendiculate within; wings falcate-obovate or oblong; keel 
curved beaked. Stamens 10, 9 connate into a sheath cleft above ; 
vexillary stamen free ; filaments at apex free and more or less dilated ; 
anthers uniform. Germen sessile o-ovulate; style inflexed, 
rather compressed; stigma more or less globose, subterminal. 
Legume much plano-compressed or more rarely subterete, often 
arched or subterminal; dorsal margin deeply excavated at each 
seed, straight or scarcely depressed between seeds and there trans- 
versely separating into 1-seeded horseshoe-shaped segments. Seeds 
arched exarillate; hilum median ventral; albumen thin; cotyledons 
arched ; radicle closely inflexed, accumbent.—Herbs or undershrubs, 
usually glabrous; leaves imparipinnate ; leaflets o, entire exstipel- 
late, stipules leaf-like or membranous, more rarely scarcely visible ; 
flowers nutant, in spurious axillary pedunculate umbels; more 
rarely pedicels 1, 2 at each axil, common peduncle nearly absent ; 
bracts small or inconspicuous; bractlets 0 (Hurope, western Asia, 
northern Africa’). 
150. Stylosanthes Sw.’—Receptacle long cylindrical tubular, 
1 Yellow, often small. + Yellow.
