Base of the pistil or of its stipe usually surrounded 
by a more or less developed saucer-shaped 
disk within the staminal sheath; racemes 
terminal, or terminal and in the upper 
axils, or opposite the leaves, or if axillary, 
the leaflets with parallel oblique lateral 
veins. 
Leaflets with parallel or indistinct lateral 
veins; pods obliquely striate; leaves with¬ 
out stipels; herbs or low shrubs. 
Leaflets netted-veined; pods not obliquely 
striate; leaves mostly with stipels; trees or 
(ours) woody vines. 
Base of the pistil or its stipe not surrounded by a 
disk; racemes always axillary; leaflets not 
with parallel oblique lateral veins. 
Pods flat, or if terete with prominent sutures, 
neither inflated nor with even a vestige 
of a longitudinal partition. 
Flowers in fascicles, on short branches 
arising in the axils of fallen leaves; 
leaves abruptly pinnate; banner usually 
enveloping the other petals. 
Flowers in axillary racemes; leaves odd- 
pinnate, except in some species of 
Coursetia and occasionally in Olneya; 
banner mostly spreading. 
Pods more or less inflated or completely or 
partially 2-celled, by the intrusion of 
one or both sutures. 
Style bearded along the upper margin; 
pods always i-celled and inflated. 
Style glabrous, or bearded only around 
the stigma. 
Anther-cells not confluent; pods not 
prickly; plant not glandular-dotted. 
Anther-cells confluent at the apex; 
pods in ours prickly; plant glandu¬ 
lar-dotted.

Herbs or shrubs, with alternate odd-pinnate leaves, persistent stipules, 
but no stipels, the leaflets usually with parallel oblique lateral veins. The 
flowers are racemose. The calyx is campanulate 5-lobed, but the upper 
lobes are often more or less united. The corolla is truly papilionaceous, 
the petals are more or less clawed, the banner is broad and spreading. The 
stamens are monadelphous or diadelphous, inserted on a more or less de¬ 
veloped campanulate disk. The style is glabrous throughout or more or 
less hairy around the stigma. The legume is elongate, flat, 2-valved, 
usually obliquely striate. The seeds are reniform or transversely oblong, 
i.e., their longer axis parallel to the axis of the pod.
