 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.

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. [Wistarm Nutt.] 

 Wisteria. 



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



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



1. Bradleia frut6scens (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 macrostdchys (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,

 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.
