Orver LII. BIGNONIACEZ. 
Orb. CHa. Calyx divided or entire. Corolla tubular, generally irregular 
4—5-lobed. Stamens 5, but either 1 or 3 of them are sterile. Ovarium 2- 
celled, guarded by a glandular disk. S#gma bilamellate. Capswule 2-valved, 
2-celled. | Dissepiment parallel or contrary. Seeds compressed, winged. 
Albumen none.—The structure of the fruit and placentation of the seeds 
readily distinguish this order from its allies. (G. Don.) 
Leaves simple or compound, opposite, exstipulate, deciduous or sub- 
evergreen ; serrated or entire. Flowers terminal and axillary. — Shrubs, 
climbing by tendrils ; natives of North America and China. 
The genera which contain hardy species are thus distinguished : —

Lobes of anthers divaricate. Stigma bilamellate. Capsule silique-formed, 
2-celled ; having the dissepiment parallel with the valves. Seeds disposed 
in 2 rows, imbricate, transverse, with membranous wings. (Don’s Mill.) 
Leaves compound, opposite, sub-evergreen ; conjugate, stipulate, _ tri- 
foliolate. Flowers axillary, usually panicled. — Shrubs, usually scandent, 
furnished with tendrils. The only hardy species is a deciduous climber, a

Spec. Char., Fc. Climbing. Leaves conjugate ; leaflets 
cordate-oblong ; lower ones simple. Tendrils small, 
trifid; the lobes bifurcate. Peduncles axillary, 1-

A climbing deciduous shrub. North America, in 
the more southern parts. Stem 15 ft. to 20 ft.

e 
A very ornamental wall climber, but it requires a 
sheltered situation and favourable exposure, in order ‘y 
to flower freely. In sheltered situations, in a climate 4206; 2B: capreolsta: 
not colder than that of London, it forms a very desirable shrub for covering 
latticework, either forming the support of a verandah, or the sides and roof 
vf a berceau or bower.
