632 ARBORETUM AND FRU‘TICE1UM. PARTY III. 
Spec. Char., §c. Leaves with 2 pairs of linear, gla- 
brous, approximate leaflets near the tip of the 
petiole, which is very short. Stipules and petioles 
spinescent. Pedicels solitary, and nearly the 
length of the calyx. Calyx nearly equal at the 
base. Leaflets acute, crowded, usually in the axils ‘ 
of trifid spines. Flowers yellow. (Dee. Prod, ii. ga\V7 ~

Variety. 
x C. p. 2 arendria Fisch. in Litt. has linear- 
cuneate leaflets, and pedicels rather longer 
than the calyx. 
Description, §c. A low shrub, scarcely a span high, on the Altaic Mountains, 
but growing much higher in fayourable situations. It has large trifid spines, 
slender leaves, and small flowers. The leaflets are remarkable for being in 
fours, disposed in the form of a star, in the axils of the spines. The young 
shoots are of a fine yellow, very tough, and fit for being used as withs. Pallas 
says that, in favourable situations, this shrub attains the height of 6 ft. ; but, in 
British gardens, it is seldom seen above 4 ft. high, except when grafted as a stand- 
ard on C. arboréscens, when it forms a small tree of very singular appear- 
ance. It was cultivated by Miller in 1751, and is not untrequent in British 
gardens. It is generally propagated by suckers, or by grafting. Plants, in the 
London nurseries, are 2s. 6d., or, grafted standard high, 7s. each; and at 
Bollwyller, 1 franc 50 cents.

Spec. Char., §c. Leaves with 2—4 pairs of cuneate- 
linear glabrous leaflets. Stipules small, spinose. 
Adult petioles permanent, strong, and spinose, twice 
the length of the leaflets. Flowers solitary, 
almost sessile, and of a bright yellow. Le- 
gume rather compressed. (Dons Mill., ii. 
p. 243.) A spiny shrub, abounding in gra- 
velly arid situations in Siberia, and also said 
to be plentiful in China, about Pekin, where 
branches of it are stuck in clay upon the tops 
of the walls, in order that its spines may pre- 
vent persons from getting over them. (Pail. 
Fi. Ross., i. f. 44.) In British gardens, into 
which it was introduced in 1755, this species N 
grows to the height of 3ft. or 4ft.; and flowers in April and May. 
It is propagated by seeds, cuttings, or grafting; and plants, in London, are 
from 1s. 6d. to 2s. 6d. each.
