ARBORETUM ET FRUTICETUM BRITANNICUM. 



Order LII. BIGN0N/^C^. 



Ord. Chah. 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; Stigvia bilamellate. Capsule 2-valvedj 

 2-celled. Dissepiment parallel or contrary. Seeds compressed, wingedj 

 Albumen none. The structure of the fruit and placentation of the seed^ 

 readily distmguish this order from its allies. (6r. 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 : 



BiGNO^N/^ Tourn. Calyx 5-toothed. Dissepiment of the fruit parallel. 

 Te'coma Juss. Calyx 5-toothed. Dissepiment of the fruit contrary. 

 Cata'lpa Juss. Calyx 2-parted. Dissepiment of the fruit parallel.

J 1. B. CAPREOLATA L. The tendriled Bignonia, or Trumpet Flowe 



Lin. Sp., 870. ; Hort. Cliff., 317. ; Don's Mill., 4. 



Mag., t. 864. ; and our fig. 1286. 



Spec. Char., S/'c. Climbing. Leaves conjugate; leaflets 

 cordate-oblong ; lower ones simple. Tendrils small, 

 trifid ; the lobes bifurcate. Peduncles axillary, 1- 

 flowered, crowded. Calyx entire. Corollas reddish 

 yellow. Follicles flattened, 1 ft. long. {Don's Mill.) 

 A climbing deciduous shrub. North America, in 

 the more southern parts. Stem 15 ft. to 20 ft. 

 Introduced in 1710. Flowers orange brown; June 

 and July. 



A very ornamental wall climber, but it requires a 

 sheltered situation and favourable exposure, in order 

 to flower freely. In sheltered situations, in a climate - , 



not colder than that of London, it forms a very desirable shrub for c.-en"-- 

 btticework, either forming the support of a verandah, or the sides aj ^'^'' 

 of a berceau or bower. /
