232 NATURAL HISTORY OF PLANTS. 
hilum; embryo fleshy ; cotyledons thick; radicle short, nearly 
straight or curved, accumbent.—Annual or perennial herbs; leaves 
imparipinnate; terminal leaflet similar to remainder (i.e. mem- 
branous and dentate or cut) or ending in a spine or small tendril ; 
stipules membranous, adnate to base of petiole; flowers’ solitary or 
few, pedicellate on a subaxillary peduncle; bracts small; bract- 
lets 0 (Mediterranean, Western and Central Asia’). 
6? Abrus L.i—Calyx truncate; teeth 4, 5, very short or obsolete. 
Petals elongated, arched or faleate; keel a little longer than wings. 
Stamens 9; filaments scarcely perigynous, connate into a sheath 
cleft above; anthers uniform. Germen subsessile o-ovulate; style 
short curved beardless; stigma minute capitate. Legume oblong 
or linear, plano-convex, more or less septate between seeds, 2-valved ; 
seeds subglobose or ovoid, shining.—Shrubs or undershrubs, slender, 
-often turning ; leaves paripinnate ; petiole terminating in an abortive 
bristle; leaflets oc-jugate exstipellate ; flowers* racemose articulated ; 
racemes terminal or axillary, each terminating a short, almost leafless 
branch’ (4/7 hot regions’). 
II. PHASEOLEA. 
7. Phaseolus L.—F lowers irregular resupinate ; receptacle cupuli- 
form, lined by a disk produced into a tube round base of gynzceum. 
Calyx gamosepalous; lobes or teeth 2, posterior nearly free or 
connate to a variable height, imbricated in estivation. Corolla 
papilionaceous: standard suborbicular, recurved patent, or rather 
twisted, at base thickened fleshy, subappendiculate at inflexed 
margins; wings obovate or oblong, about equal to or longer than 
standard, adhering to keel in a variable manner and often twisted

® This genus, anomalous among Viciee, and 
haying some affinity with Dalbergiee, has by 
some authors been placed among Phaseolee 
(where it is similarly anomalous), while by 
others it is made the type of the sub-tribe 
Abrinee (Wiaut & ARN., Prodr., i. 236 ;— 
ENDL., Gen., 1301).
