 what viscid : stems branched from the base, the branches 4-6 dm. long, spreading, assurgent, 

 flexuous, more or less angled ; leaves oblong-obovate in outline, 6-12 cm. long ; stipules 

 subulate, caducous ; petioles 1 cm. long ; leaflets 3-11, the blades of the lateral ones oblong- 

 obovate, 1-3 cm. long, glabrous and yellowish green above, strigose with whitish hairs and 

 becoming somewhat purplish beneath, truncate at the apex, apiculate : peduncles 8-15 cm. 

 long, hirsute : bracts 5-7 mm. long : pedicels remote, each longer than its calyx : calyx- 

 lobes lanceolate, acuminate : corolla 1 cm. long ; standard minutely pubescent : pods 3.5-4 

 cm. long, about 4 mm. wide, straightish, strigillose.

15. Cracca chrysophylla (Pursh) Kuntze. Hoot woody, elongated. Foliage pubes- 

 cent with more or less lustrous hairs. Stems prostrate, 3-10 dm. long, dichotomously 

 branched : leaves oval in outline, 3-5 cm. long, with very short petioles, or sessile ; stipules 

 subulate, caducous ; leaflets leathery, 3-7 or rarely 1, the blades of the lateral ones cuneate- 

 obovate, 1.3-3 cm. long, obtuse or often retuse, sometimes apiculate, the terminal one con- 

 spicuously larger than the rest : peduncles two-sided, 4-6 cm. long : pedicel shorter than 

 the calyx pr a little longer : calyx-lobes lanceolate or lanceolate-subulate, longer than 

 the tube : corolla becoming purple ; standard fully 1 cm. long : pods 3-5 cm. long, nearly 

 straight, erect or spreading. 



In sandy pine lands, Georgia to Florida and Mississippi.

 smaller. Stems prostrate, 2dm. long or longer, slender: leaves 1.5-3 cm. long; leaflets 

 5-7, the blades of the lateral ones oblong to obovate, 6-12 mm. long, rounded, truncate or 

 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. [ Wistaria Nutt. ] 

 WISTERIA. 



Racemes 4-10 cm. long : calyx-lobes shorter than the tube. 1. B. frutescens 



Racemes 20-30 cm. long : calyx-lobes as long as the tube or the lower ones longer. 2. B. macrostachys. 



1. Bradleia frutescens (L. ) Britton. A slender vine becoming 12 m. long. Leaves 

 1-2 dm. long : leaflets 9-15, the blades oblong to ovate or lanceolate, 1.5-6 cm. long, 

 acute or slightly acuminate at the apex, acute or obtuse at the base: racemes ovoid to 

 oblong, 4-10 cm. long, the rachis and pedicels lanuginous : calyx pubescent with appressed 

 hairs, 6-7 mm. long : corolla lilac-purple, 15-18 mm. long ; standard with a suborbicular 

 blade which has 2 incurved auricles at the base ; wing-petals oblique, with a slender and 

 short auricle on either side the claw : pods linear, 5-10 cm. long, flat. 



In thickets and low grounds, climbing over trees, Virginia to Florida. Spring. 



2. Bradleia macrostachys (T. & G. ) Small. A stout climbing vine 1-8 m. long. 

 Stems becoming 2-3 cm. thick : leaves 2-3 dm. long or rarely shorter : leaflets usually 9, 

 the blades ovate or oval-ovate to elliptic or elliptic-lanceolate, 3-7 cm. long, acuminate, 

 ciliate, rounded or cordate at the base : racemes 2-3 dm. long, drooping, the rachis and 

 pedicels densely hirsute and glandular : calyx pubescent like the pedicels ; lobes lanceolate 

 or narrowly lanceolate, acuminate, the lateral ones about as long as the tube and the lowest 

 one much longer : corolla lilac-purple or light blue ; standard with a short claw and sub- 

 orbicular blade rather broader than high, about 1.5 cm. in diameter : wing-petals 1.5 cm. 

 long, the subulate-linear spur about as long as the claw : pods 7-12 cm. long, torulose, 

 reddish brown, rather obtuse : seeds oblong or cylindric-oblong, black, lustrous.
