342. Cytisus (Labrnum) zlpmus. 
Spec. Char., §e. Branches glabrous and terete. Leaves petiolate; leaflets 
ovate-lanceolate, rounded at the base. Racemes pendulous. Pedicels and 
calyxes puberulous. Legumes glabrous, few-seeded, marginate. (Don’s 
Mill.) A deciduous low tree. Found in Carinthia, in the Alps of Jura, 
on Mount Cenis, and on the Apennines. According to some, it is also 
found wild in Scotland ; but, though it is much cultivated in some parts of 
Fifeshire and Forfarshire, it is far from being indigenous there. Height 
20 ft. to 30 ft., sometimes much higher in a state of cultivation. It was 
introduced into Britain about the same time as the other species, viz. 1596 ; 
and was, probably, for a long time confounded with it; for which reason we 
shall treat of the two species, or races, together. Flowers yellow; May 
and June. Legume brown; ripe in October. 
Varieties. 
_ # C.(L.) a. 2 péndulus has pendulous branches, and, in the foliage and 
legumes, seems intermediate between C. Labarnum and C. (Z.) al- 
pinus. This is very obvious in a fine specimen of this variety in the 
arboretum of the Messrs. Loddiges, as shown in the plate in Ard. 
Brit., st edit., vol. v. The pendulous variety of C. Labirnum is 
a much less robust plant. 
* C. (L.) a. 3 purpurascens Hort., C. LZ. purptreum Hort., C. Adami 
Poir., C. L. coccineum Baum. Cat., the purple Laburnum, the scarlet 
Laburnum, is not a hybrid between C, Labérnum and C. purptreus, 
as was at first supposed, but a sport from a bud of CYtisus pur- 
pureus inserted in C. alpinus, in 1825, by D. Adam, a nurseryman at 
Vitry, near Paris. The flowers are of a reddish purple, slightly 
tinged with buff, and are produced in pendent spikes, 8 in. or more 
long. A few years after this sport was originated, it was found that 
it had a strong tendency to return to the original kinds ; and that 
from one bud or graft, branches were produced of the true C¥tisus 
purpureus, of the true Zabirnum (either the Alpine or the common,
