Bul-er, in Nat. 1SG4, p. 96. 



R. cjesia, Borrer, in J/ooL Brit. Fl. (in part, not E. B.). 



Stem slightly ai'ching ; prickles rather slender, slightly curved. 

 Leailets broadly ovate, rather thin, sparingly hairy when young but 

 sub-glabrous and glaucous-green when mature above, glaucous and 

 thinly-hairy beneath ; petioles with woolly hairs and a few glaud- 

 tipped setae. Stijmles and bracts sub-glabrous, " hairy on tlie 

 back" (Baker), sparingly ciliated with gland-tipped setae. Pedicels 

 naked, as long as or shorter than the bracts. Styles sparingly 

 hairy. Fruit subglobose, ripening in the end of September. 

 Sepals leaf-pointed and pinnate, glabrous on the outside, with 

 tomentose edges, sparingly ciliated with gland-tipped seta3, falling 

 before the fruit is ripe. 



Marrick Moor, and by tlie Swale near Keld, Yorkshire, also by 

 the bridge between Swallwell and Axwell Park, Durham. 



The form from thickets by the side of the Swale has the sepals 

 glandular all over the outside. 



IG. Rosa dumetorum. "ThuiU." Woods. 

 Baker, in Nat. 18G4, p. 96. 



Stem arching; prickles stout, hooked. Leaflets elliptical or 

 oval, more or less acuminate, moderately thick, thinly-hairy when 

 young but sub-glabrous and greyish-green when mature above, grey 

 and thinly-hairy (especially on the veins) beneath, simply but irre- 

 gularly and shallowly serrate, the serratures not gland-tipped but 

 ciliated with woolly hairs ; petioles woolly, with very few gland- 

 tipped setae. Stipules and bracts sub-glabrous (pubescent in one 

 of the specimens sent me by Mr. Baker, authenticated by 

 M. Crepin), sparingly ciliated with very short gland-tijjped sette 

 and woolly hairs. Pedicels naked, as long as or shorter than the 

 bracts. Styles thinly-hairy. Fruit usually large, ovoid-urceolate, 

 " sometimes subglobose" (Baker, /. <?.), ripening in the end of Sep- 

 tember. Sepals leaf-pointed and copiously pinnate, glabrous on the 

 outside, tomentose on the edges, scarcely ciliated with gland-tipped 

 setae, falling before the fruit ripens.
