Spec. Char., fyc. Prickles strong, hooked. Leaflets simply serrated, pointed,

 and thickets. Flowers rather large, pale red, seldom white. 

 Fruit ovate, bright scarlet, of a peculiar and very grateful fla- 

 vour, especially if made into a conserve with sugar. The pulp 

 of the fruit, besides saccharine matter, contains citric acid, 

 which gives it an acid taste. The pulp, before it is used, 

 should be carefully cleared from the nuts or seeds. A shrub, 

 growing to the height of 6 ft. or 10 ft., and flowering in June 

 and July. 

 Varieties.

 the species in having remarkably strong shoots, bearing 

 sometimes great plenty of flowers, 

 at R. c. 3 nuda Woods 1. c. differs very slightly from the 



species. 



ft R. c. 4 adphyila Lind. Ros., p. 99. ; R. aciphylla Rau., 69.

 and its singular habit of growth. The leaves are smooth on both 



surfaces, and the flowers are smaller than those 



of the species. 

 R. c. 5 cegyptiaca Lind. Ros., p. 99. ; R. indica 



Forsk. JEgyp. Descr., 113.; has the leaflets
