J* C.p. 2arendria 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. arborescens, it forms a small tree of very 

 singular appearance. Increased by suckers or by grafting.
