cels minute. Vexillum broad, reflexed, 9-10 lines long, with a folded claw, the 
limb with inflexed ears at base. Carina broadly falcate, much curved at the point, 
nearly forming a complete circle, and having on one side above the middle a conical, 
prominent spur. Legume sessile, linear, straight, hispid, 3-4 inches long, 2 lines 
wide. Flowers greenish-yellow, tinged with purple. This plant is common to South 
Africa, Australia, S. America and tropical Asia. 2 = 
5. V. triloba (Walp. Linn. XIII. 534); procumbent, herbaceous; 
stem retrorsely-hispid or glabrescent ; leaflets hastate-trilobed, the lobes 
obtuse, the medial lobe much the longest ; lateral leaflets unequal-sided, 
their upper lobe obsolete ; stipules peltate, constricted at the insertion, and 
prolonged downwards, ovate ; peduncles elongate, 2-flowered at the sum- 
mit ; calyx campanulate, the lobes falcato-lanceolate, longer than the 
tube ; carina broadly ovato-falcate, acute ; legume straight, terete, his-

Stems = feet long or more, weak, somewhat angular. Leaflets variable in 
breadth, and in incision ; sometimes narrow-hastate, 1-2 inches long, the medial 
lobe 2-6 lines wide, 10-15 lines long, the lateral widely spreading, narrow-oblong, 
5-6 lines long, 2 broad ; sometimes the terminal leaf only is distinctly 3-lobed, the 
lateral leaflets being obliquely-ovate and subacute. The stipules are constantly pel- 
tate in insertion, vertical, rigid, 2-lobed, the lobes directed contrary ways. Pods 3-33 
inches long, 2 lines wide. Var. 8. is an extravagantly narrow leaved form, but has

the remarkable stipules of the species. 
6. V. decipiens (Harv.); prostrate, herbaceous : stem and petioles 
retrorsely hispid; leaflets hastate, 3-lobed, the middle lobe acute, lateral 
short, obtuse, lateral leaflets unequal-sided, obsoletely lobed ; stipules 
sessile, lanceolate, small; peduncles eq g or exceeding the leaves, 
2-flowered at the summit; calyx campanulate, its lobes from a broad 
base subulate, equalling the tube; carina falcate, subacute; legume 
straight, somewhat constricted between the seeds. Dolichos ? decipiens,

(Herb. Hk., Bth., Sd.) : : 
Very like V. triloba, but the stipules are basificed, not peltate, the flowers are 
smaller and the calyx different. Stems flagelliform, 2 feet long or more, striate, and — 
rather roughly hispid. Petioles uncial. Stipellze lanceolate, equalling the petiolules. 
Leaflets about 1-14 inch long, $-3 inch wide, green, subglabrous, except on the 
ribs, veins, and margin, the middle lobe mostly acute. Flowers 6 lines long, seem- 
ingly greenish-rosy. Young pods only seen. "e
