characters of the proper Pulse Family , viz. the suborder 
PAPILIONACEiE.* 
Synopsis, 
I. Corolla truly papilionaceous. Radicle mostly incurved. 
Tribe 1. VICIEiE.— Stamens diadelphous, 9 united by their fila¬ 
ments into a sheath split on the upper side (next the standard) 
where the 10th is free. Pod continuous and 1-celled. Cotyle¬ 
dons very thick and fleshy (as in a pea), not rising to the sur¬ 
face, but remaining underground in germination. — Herbs, 
with abruptly pinnate leaves, the common leaf-stalk produced 
into a tendril or bristle. Peduncles axillary. 
1. Vicia. Style bearded round the apex, or down the anterior side. 
2. Lathyrus. Style bearded on the posterior side, flattened. 
Tribe 2. PHASEOLEiE. — Stamens more or less diadelphous 
(9 and 1). Pod continuous, not jointed, nor more than 1-cell- 
ed, except by cellular matter sometimes deposited between the 
seeds. Cotyledons thick and fleshy, usually rising to the sur¬ 
face, but remaining nearly unchanged (seldom foliaeeous) in 
germination. — Twining or trailing plants, with odd-pinnate 
leaves of 3-several leaflets, mostly stipellate, destitute of ten¬ 
drils. Flowers often clustered in the racemes. 
* Keel twisted. Cotyledons thick, nearly unchanged in germination. 
. Phaseolus. Keel spiral. Leaves 3-foliolate, stipellate. 
4. Arios. Keel incurved, at length twisted. Leaves 5- 7-foliolate. 
* * Keel not twisted. Leaves 3-foliolate. 
r 3. Galactia. Calyx 4-cleft. Bracts deciduous, not striate. 
6. Amphicarpjea. Calyx 4 -5-toothed. Peduncles many-flowered. 
Bracts persistent, striate. 
* 7. Clitoria. Calyx tubular, 5-cleft, 2-bracteolate. Peduncles 1-3- 
flowered. Standard spurless. 
8 - Centrosema. Calyx short, 5-cleft, 2-bracteolate. Peduncles 
few-flowered. Standard spurred on the back. 
Tribe 3. HEDYSARE^E. — Stamens monadelphous or diadel¬ 
phous. Pod (a loment) separating transversely into 2 -several 
1-seeded indehiscent joints, or rarely reduced to one such joint. 
Cotyledons becoming green leaves in germination. Leaves 
odd-pinnate: leaflets 3-many, mostly stipellate. 
9. iEscHYNOMENE. Stamens equally diadelphous (5 and 5). Pod 
several-jointed. Flowers all perfect. Leaflets numerous.
