LEGUMINIFER®. 79 
2 inches long; leaflets oval or elliptical, 4 to 4 inch long, rather 
distant. Stipules extremely small, deltoid, often scarcely discernible 
in the lower leaves. Peduncles filiform, about as long as the leaves. 
Flowers + inch long, bright-yellow with red streaks. Calyx very 
long and slender, cylindrical-funnel-shaped. Pods not diverging, 
8 to 1 inch long, curved upwards into a bow, breaking into 10 or 
14 indehiscent 1-seeded joints, the last one attenuated into a beak, 
but generally bearing a seed at the base. Plant dull glaucous-green, 
sub-glabrous, with a few adpressed hairs on the leaves (especially 
on their midribs) and the upper part of the stem. 
Sand Bird’s-Foot. 
French, Ornithope sans Bractées. 
GENUS XIV—-HIPPOCREPIS. Linn. 
Calyx campanulate, with 5 teeth; teeth sub-equal, with the 2 
upper ones united to their middle. Standard with the lamina spread- 
ing, orbicular, attenuated into a slender claw distant from those 
of the other petals; keel large, terminating in an acuminate beak 
directed towards the standard. Stamens diadelphous, with the alter- 
nate filaments dilated towards the apex. Pod much compressed, 
straight or curved, articulated, breaking into numerous indehiscent 
1-seeded joints, which are more or less deeply notched on the 
upper side, with a raised band surrounding the notch in the form 
of a horse-shoe, smooth except on the raised portion, which is often 
clothed with minute raised points. 
Herbs or undershrubs. Leaves with numerous pairs of pinne, 
and stipules slightly adnate to the petioles. Flowers yellow, gene- 
rally in umbellate stalked axillary heads, more rarely solitary or 
in pairs. 
The derivation of the name of this genus is from imzoc (hippos), a horse, and konme 
(krepis), a shoe, in reference to the shape of the recesses of the pods, which are curved 
in such a manner as to resemble a chain of horse-shoes. 
SPECIES I—HIPPOCREPIS COMOSA. Linn. 
Puate. CCCLX XX. 
Rootstock much branched. Stems very numerous, decumbent, 
much branched, and somewhat woody at the base. Peduncles 
longer than the leaves. Pod curved downwards, undulated on the 
lower margin, deeply notched on the upper opposite each seed, and 
having on the sides over each seed a crescent-shaped raised pro- 
tuberance covered with minute rough points.
