ARBORETUM ET FRUTICETUM 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. P"lowers 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 pf the jellow 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 chpping, 

 and would form a beautiful garden hedge.

S]3ec, Char., Sfc. 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 2 ft. to 3 ft. 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 junceum, are partly desti- 

 tute of leaves.

Derivation. Named in honour "of Caspar Jl'istar, late Professor of Anatomy in the University of 



Pennsylvania. {Do7i'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 DeCandoUe's Prodromus, and some other works. Wistaria is erroneously spelled 



WistJ:na. 



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

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

 bicallose. JVings 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-ceiled, rather torulose at the seeds- 

 (Doh'.s Mill.) 



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 gro^vth, 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 everj' joint if laid 

 down during summer as they grow. They may also be propag-ated by cuttings 

 of the roots ; or by seeds.
