Variety. 
«« C. p. 2 arendria Fisch. has linear-cuneate leaf- 
lets, and pedicels of the flowers generally 
longer than the calyx. ¢ 
This species 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. 
When grafted as a standard on C. arboréscens, it forms a small tree of very 
singular appearance. Increased by suckers or by grafting.

beria, in gravelly 
arid situations; 
and also said to be

where _ branches 
of it are stuck in 
clay upon the tops of the walls, in order that its 
spines may prevent persons from getting over 
them. (Pall. Fl. Ross.) Height 3 ft. to 4 ft. In- 
troduced in 1755. Flowers yellow; April and
