143 THE NATURALIST. 



uniform, the base three-eighths of an inch deep, the prickle ahout the 

 same length, robust below and strongly hooked. Well developed leaves 

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

 the apex of the terminal leaflet, which is usually obovate and rounded but 

 little at the base, and measures about an inch long by from five eighths to 

 three quarters of an inch broad. Leaflets dull green and glabrous on the 

 upper surface, much paler and often glaucous beneath, almost naked, or 

 hairy upon the midrib only, the teeth broad-based and not deep, and only 

 casually double, the lower ones often gland-tipped, the petioles slightly 

 hairy and setose and furnished usually with three or four slender falcate 

 aciculi. Stipules and lanceolate bracts naked or very nearly so on the back, 

 more or less densely fringed with setsD. Peduncles forming a close cluster 

 when the shoot is at all well developed, much lengthened out but only 

 spreading very little, purple in exposure, usually clothed densely with 

 almost sessile purple glands, occasionally almost naked. Calyx tube vary- 

 ing from ovate or elliptical to subglobose, purplish and bloomy, naked or 

 glandular just at the base, the segments usually not more than half an 

 inch long, naked on the back, hardly dilated or leafy at the point, broad- 

 bladed, and either entire or furnished only with one or two small linear 

 entire pinnse. Petals white, very rarely tinged to any considerable extent 

 with red, considerably exceeding the sepals, the corolla measuring an inch 

 and a half across, and spreading out widely when fully expanded. Styles in a 

 prominent hairless column, which usually exceeds the stamens. Fruit 

 varying from broadly ovate or elliptical to subglobose, not exceeding half 

 an inch long, turning red in October, by which time the sepals have all 

 fallen. 



This is common in many parts of the north of England, but I have 

 not seen it anywhere wild at an elevation of more than 200 yards, and in 

 Scotland not from any further North than Kincardine. M. Deseglise ap- 

 plies the name arvensis to the R. Candida of Scopoli, a closely allied plant, 

 with solitary glandless peduncles, but there can be no doubt that what 

 Hudson intended is our common York rose, which is the R. arvensis of 

 De Candolle, the R. repens of Scopoli, Rau, and Reichenbach. A plant 

 which has been gathered by Mr. T. R. A. Briggs in Devonshire, has much 

 stronger and taller stems than in the type, in combination with more hairy 

 leaves, roughly hairy petioles, and peduncles with more strongly stalked 

 and more numerous glands. There can be I think but little doubt of the 

 identity of R. arvensis of Borrer in Hooker's British Flora, with R. librae-
