retuse at the apex and often apiculate, resembling those of Stylosanthes riparia: peduncles 
about as long as the leaves or longer: calyx-lobes triangular, shorter than the tube: 
corolla becoming purple ; standard about 1 cm. long: pods 2 cm. long or less. 
In sandy soil, Florida and Alabama to Louisiana. 
13. BRADLEIA Adans. 
Perennial vines, with climbing woody stems. Leaves alternate: blades unequally 
pinnate: leaflets often subtended by stipels, the blades entire. Flowers perfect, in 
terminal racemes. Calyx slightly 2-lipped, the 2 upper lobes partially united and shorter 
than the 3 lower. Corolla blue, purple or rarely white: standard broad, abruptly con- 
tracted into a claw with 2 appendages at the top: wings somewhat curved : keel incurved, 
obtuse. Stamens diadelphous. Anthers alike. Ovary stalked. Style inflexed. Ovules 
numerous. Pod elongated, 2-valved, flat, constricted between the seeds. [ Wistarta Nutt. ] 
WISTERIA.

oblong, 4-10 em. long, the rachis and pedicels lanuginous : calyx pubescent with ap Dr 
hairs, 6-7 mm. long: corolla lilac-purple, 15-18 mm. long; standard with a suborbicu 
blade which has 2 incurved auricles at the base ; wing-petals oblique, with a slender an 
short auricle on either side the claw : pods linear, 5-10 cm. long, flat.
