BAKER ON BRITISH ROSES. 63 



texture like that of R. caiiina, ovate or ovate-urceolate in shape, measuring 

 about five-eighths of an inch deep by three-eighths to half an inch broad, 

 ripening in September, by which time the sepals have all or most of them 

 fallen. 



Of our species, this is only in danger of being confounded with the 

 last, from which it differs by its habit of growth, which resembles that of 

 R. canina, by its uniform prickles, which are less numerous, more strongly 

 toothed, and more robust below than the large ones of ruhlginosa, by the 

 shape of its leaves and much fainter odour of their glands, by the shape 

 of its calyx tube and fruit, the different texture and pleasant acid taste of 

 the latter when ripe, by its glabrous styles, and narrow-bladed long-pointed 

 sparingly pinnate sepals, which fall before the fruit ripens. It is not 

 known in Scandinavia. M. Crepin identifies our plant with the Belgian 

 R. nemorosa of Lejeune, the R. Libertiana of Trattinick, and sends me what 

 is evidently the same plant as ours, but a specimen from Cobourg in 

 Mr. Watson's collection, marked by Herr Hornung as the authenticated 

 plant of Lejeune, is evidently only a sylvestral form of Pi. rubiginosa. M. 

 Boreau and M. Deseglise have both informed me that our plant, as illus- 

 trated by specimens which I sent, is identical with the French plant 

 which they describe as nemorosa. Their R. micrantlia is a low bush with 

 leaves not more than half an inch long by three-eighths of an inch broad, 

 the terminal one narrowed at the base, slender scarcely curved prickles 

 not more than a quarter of an inch long, small prickly calyx tube, short 

 almost entire sepals and much smaller ovate-urceolate fruit. I have 

 gathered our plant in two stations in Yorkshire, and possess it from a 

 third, all three being very slightly elevated above the sea level. I have 

 not seen it from anywhere further north, but it is evidently widely diffused 

 through the central and southern counties. 



VIII. — K. BoRRERi. Woods. Stems six to eight feet high, arched, 

 with ascending flexuose branches. Prickles uniform, their bases three- 

 eighths to half an inch deep, the prickle about three-eigbths of an inch 

 long, strongly hooked and the lower part robust. Well developed leaves 

 of the barren stem three and a half to four inches from the base to the 

 apex of the terminal leaflet, which varies from elliptical to broadly ovate 

 with a cordate base, and measures from an inch and a quarter to an inch 

 and a half long by about an inch broad. Leaflets full or deep green above, 

 thinly hairy all over when young, glabrous when mature, paler beneath, 

 hairy principally upon the veins, thinly sprinkled over with small green
