PARI' III 



Spec. Char., Sfc. 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. {Dec. Prod, ii, 

 p. 268.) 



Variety. 



C. p. 2 arenaria 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 favourable 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. arborescens, when it forms a small tree of very singular appear- 

 ance. It was cultivated by Miller in 1751, and is not unfrequent in British 

 gardens. It is generally propagated by suckers, or by grafting. Plants, in the 

 London nurseries, are 2s. Gd., or, grafted standard high, 75. each ; and at

Spec. Char., Sfc. 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. (Don's 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. {Pall. 

 Fl. Boss., i. f. 44.) In British gardens, into 

 which it was introduced in 1 755, this species 

 grows to the height of 3 ft. or 4 ft. ; and flowers in April and May. 



It is propagated by seeds, cuttings, or grafting; and plants, in London, are 



from Is. 6d. to 2s. 6d. each.
