SECT. IX. CANINE (from canis, a dog; because R. canlna

 red, seldom white. Fruit ovate, bright scarlet, of a peculiar and 

 very grateful flavour, 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 seeds.

 from the species in having remarkably strong shoots, bearing 

 sometimes great plenty of flowers.

 last, having the calyx tube globose and the prickles nearly 

 straight. Gathered by Mr. Woods at Ambleside.

 both surfaces ; flowers smaller than those of the species. H . H.
