joints separate slowly and unobviously, but they do separate. (Dec. Prod.) 
A bushy glabrous shrub. Middle and Southern Europe, in thickets and 
hedges. Height 4ft. 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., §c. Shrubby, glabrous. Branches rush-like, round, bearing but 
few leaves ; the latter are attended by minute stipules, and Qs, anf 
have 8—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. 409. C. jancea. 
It deserves a place in collections, on account of the singularity of its rush- 
like slender branches, which, like those of Spartium janceum, are partly desti- 
tute of leaves.

Derivation. Named in honour of Casparv 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. specidsa; but which DeCandolle has changed to W. 
frutéscens. In DeCandolle’s Prodromus, and some other works, Wistar¢a is erroneously spelled 
Wistérza. 
Gen. Char, Calyx campanulate, somewhat bilabiate, upper lip with two short 
teeth, lower one with 3 subulate teeth. Corolla papilionaceous. Veaillum 
bicallose. Wings conforming to the keel, which is 2-edged. Stamens diadel- 
phous. Nectariferous tube girding the stipe of the ovary. Legume standing 
ona short stipe, coriaceous, 2-valved, 1-celled, rather torulose at the seeds. 
(Don’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 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.
