ARBORETUM ET FRUTICETUJV1 BRITANNICUM. 



joints separate slowly and unobviously, but they do separate. {Dec. Prod.) 

 A bushy glabrous shrub. Middle and Southern Europe, in thickets and 

 hedges. Height 4 ft. to 10 ft. Introduced in 1596. Flowers yellow ; April 

 to June. Legume brown ; ripe in September. 



Before the flowers are expanded, the corolla is partly red externally, mostly 

 so towards the tips of the petals ; and the mingling of the yellow flowers, with 

 flower-buds more or less red, and the elegant foliage, produce a fine effect. It 

 flourishes most in a sunny sheltered situation, and a dry soil. It bears clipping, 

 and would form a beautiful garden hedge.

Spec. Char.y fyc. Shrubby, glabrous. Branches rush-like, round, bearing but 

 few leaves ; the latter are attended by minute stipules, and 

 have 3 7 leaflets, that are linear oblong, obtuse, and rather 

 fleshy ; the lowest leaflets being rather distant from the base 

 of the petiole. The flowers are yellow, 5 7 in an -umbel. 

 The claws of the petals are scarcely longer than the calyx. 

 The legume is rather compressed, and its joints separate 

 obviously. (Dec. Prod.) An erect glaucous shrub. South 

 of France. Height 2ft. to 3ft. Introduced in 1756. Flowers 

 bright yellow ; June and July. Legume brown ; ripe in 

 September. 



It deserves a place in collections, on account of the singularity of its rush- 

 like slender branches, which, like those of Spartium ^'unceum, are partly desti- 

 tute of leaves.

Identification. Nutt. Gen. Amer., 2. p. 115. ; Dec. Prod., 2. p. 389. ; Don's Mill., 2. p. 348. 



Synonymes. Gl^cine sp. L., Thyrsanthus Elliot, Kraunhz'a Rafin. 



Derivation. Named in honour of Caspar Wistar, late Professor of Anatomy in the University of 



Pennsylvania. (Don's Mill., ii. p. 348.) Nuttall first characterised and named this genus, from the 



American species, which he denominated W. specibsa ; but which DeCandolle has changed to W. 



frutescens. In DeCandolle's Proitromus, and some other works, Wistana is erroneously spelled 



WistenYz. 



Gen. Char. Calyx campanulate, somewhat bilabiate, upper lip with two short 

 teeth, lower one with 3 subulate teeth. Corolla papilionaceous. Vexillum 

 bicallose. Wings conforming to the keel, which is 2-edged. Stamens diadel- 

 phous. Nectariferous tube girding the stipe of the ovary. Legume standing 

 on a short stipe, coriaceous, 2-valved, 1-celled, rather torulose at the seeds. 

 (Don's Mi/I.) 



Leaves compound, opposite, exstipulate, deciduous ; impari-pinnate. 

 Flowers bluish purple, in terminal and axillary racemes. Shrubs, deciduous, 

 twining; natives of North America and China; of vigorous growth, forming, 

 when in flower, some of the most splendid ornaments of British gardens. 

 The species are quite hardy, will grow in any soil, and are generally pro- 

 pagated by layers of the young shoots, which will root at every joint if laid 

 down during summer as they grow. They may also be propagated by cuttings 

 of the roots ; or by seeds.
