SYNOPSIS OF THE GENERA. 
diadelphous. Legumes ovate, indehiscent, one or two 
seeded, rarely oblong, and three or four seeded —Herba- 
ceous plants, with ternale leaves and stipules, adhering to 
the petioles, flowers in crowded heads or spikes. 
13. Tricon'gi1a, [Page 982.] Calyx campanulate, five-cleft. 
Keel very small, the wings and vexillum together imitating 
a tripetalous corolla. Legume oblong, compressed, or 
cylindrical, acuminate, nearly erect, many seeded.— 
Herbaceous plants, mostly strong scented, leaflets three, the 
terminal one stalked. 
14. Lo'rus, [Page 983.] Calyx tubular, five-cleft or five- 
toothed. Corolla with a beaked keel, and wings about as 
long again as the vexillum. Stamens diadelphous. Le- 
gumes cylindrical, or compressed, linear, somewhat spongy 
within, valves curved spirally on bursting. Seeds mostly 
numerous.—Herbaceous plants, with lernale leaves and 
leafy stipules. Flowers one to six terminating axillary 
peduncles. 
15. Mepica’co, [Page 986.] Calyx five-cleft, or five-toothed 
Keel obtuse. Stamens diadelphous. Legumes many 
seeded, variable in form, always falcate, or spirally twisted. 
— Herbaceous plants or shrubs, stipules leafy, mostly cut, 
leaves ternate. Flowers one to many, on axillary pedun- 
cles, yellow or purple. 
%%* Legumes of one celd, or divided by transverse articulations, 
and separating at the joints. 
16. Ono'srycnis, [Page 990.] Calyax five-cleft, equal. Keel 
obliquely truncated, wings short. Stamens diadelphous. 
Legume sessile, of one joint, indehiscent, coriaceous, com- 
pressed, one seeded, the upper margin thick and straight, 
the lower thinner, curved, toothed, spiny, or lobed.— 
Herbaceous plants, bearing spikes of red or while flowers, 
on long peduncles. 
17. Orni'tHopus, [Page 992.] Calyx elongated, tubular, five- 
toothed, unequal. Keel short, compressed. Stamens 
diadelphous. Legume elongated, curved, compressed, con- 
tracted at the joints, each joint single seeded, and sepa- 
rating equally, truncate at each end —Hairy annuals, with 
pinnate leaves, having a small stipule, adhering to the 
petiole. Flowers small, few, terminating the axillary
