and narrower. Standard large, with 2 appendages above claw; wings 
falcate with 1 appendage above claw; keel curved obtuse. Stamens 
10, 2-adelphous (9-1); more rarely vexillary stamen connate with 
remainder; anthers uniform. Germen stipitate; disk produced 
round stalk of germen into a conical sheath, unequally cleft at apex ; 
germen o-ovulate; style inflexed glabrous; stigma terminal sub- 
globose. Legume elongated torulose, continuous within, 2-valved ; 
valves somewhat coriaceous, convex. Seeds reniform exarillate.—— 
Climbing shrubs ; leaves imparipinnate; leaflets entire penniveined 
with reticulate venules; superior stipels linear, very caducous ; 
stipules usually long narrow very caducous; racemes terminal 
nutant; flowers' on rather long pedicels; pedicels articulated at 
base; bracts very caducous (China, Japan,’ North America’). 
63. Robinia L.‘—Receptacle depressed obconical, glandular within. 
Calyx gamosepalous to a considerable height; teeth short broad; 
2 superior subconnate valvate. Petals shortly unguiculate; standard 
large reflexed, bare within; wings free falcate-oblong; petals of 
curved obtuse keel connate below, valvate. Stamens 10, 2-adelphous ; 
9 inferior connate into a tube often slightly inflated at base and cleft 
above; vexillary stamen either free or connate at middle with 
remainder; anthers uniform, oppositipetalous often smaller. Ger- 
men stipitate «-ovulate; style inflexed subulate, shaggy at apex; 
stigma capitate terminal. Legume scarcely stipitate, linear plano- 
compressed, continuous within, 2-valved; valves membranous thin ; 
superior suture narrowly winged. Seeds, oblique or transverse,

thickened arilliform; albumen thin membranous; embryo fleshy ; 
radicle much inflexed, accumbent.—Trees or shrubs, nearly glabrous, 
viscous, or bristly ; leaves imparipinnate ; leaflets oo, usually stipel-
