224 ENGLISH BOTANY. 



In hedges. Common near Thirsk, Yorkshire, and prohably 

 generally distributed. 



17. Rosa imcinella. Bess. 



Baker, in Nat. 1864, p. 95. 



" Habit of growth and prickles of the normal E-. canina. Leaves 

 flat, grey-green, slightly-hairy on the upper surface when young, but 

 glabrous when mature, greyer still and hairy all over beneath, so 

 that the edge is ciliated, firm in texture, the serrations simple, 

 spreading and open, as broad as they are deep, callous at the tips, 

 the terminal leaflet broadly oval or obovate, much rounded at the 

 base ; the petioles villous, but hardly at all glandular, furnished 

 usually with 2 or 3 hooked prickles. Stipules and bracts slightly 

 hairy on the back, dentate but hardly at all gland-ciliated. 

 Peduncles naked. Calyx-tube and fruit large, broadly elliptical or 

 subglobose, the green fruit rather more pliable than in E-. platy- 

 phylla. The sepals reflexed after the petals fall, leaf-pointed and 

 fully pinnate, tomentose, and slightly glandular on the back, hardly 

 at all setoso-ciliated. Styles villous." — (Baker, I. c.) 



Banks of the Yore, at Aysgarth Force, North-west Yorkshire. 



18. Rosa platyphylla. Rau. 



Baker, in Nat. 1864, p. 95, 



Stem arching ; prickles stout, hooked. Leaflets broadly oval or 

 obovate-oval, rather firm, flat, greyish-green and glabrous above, 

 glaucous and thinly -hairy beneath, sharply deeply and irregu- 

 larly serrate, the serratures not gland-tipped ; petioles thinly 

 woolly, with gland-tipped setae and prickles. Stij)ules and bracts 

 thiuly-hairy on the back, Avith a few gland-tipped seta3 on the 

 margins, but not regularly ciliated. Pedicels naked, as long as or 

 shorter than the bracts. Styles villose. Sepals leaf-pointed, pin- 

 nate, nearly destitute of gland-tipped setae on the edges. The 

 mature fruit has not been seen either by Mr. Baker or myself, but 

 is described by M. Deseglise as ovoid, with the sepals falling before 

 maturity. 



At Giggleswick and Settle, West Yorkshire. 



Of this plant I have only seen imperfect specimens.
