ROSACEA, 223 
Mr. Baker remarks that this plant has a resinous scent, and 
that the leaves resemble those of R. tomentosa, while the fruit is 
that of normal R. canina. 
15. Rosa pruinosa. Baker. 
Baker, in Nat. 1864, p. 96. 
R. cxsia, Borrer, in Hook. Brit. Fl. (in part, not E. B.). 
Stem slightly arching; prickles rather slender, slightly curved. 
Leaflets 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 gland- 
tipped sete. Stipules and bracts sub-glabrous, “hairy on the 
back” (Baker), sparingly ciliated with gland-tipped setze. 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 sete, falling 
before the fruit is ripe. 
Marrick Moor, and by the 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. 
16. Rosa dumetorum. <“ Zhwill.” Woods. 
Baker, in Nat. 1864, 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- 
eularly and shallowly serrate, the serratures not gland-tipped but 
ciliated with woolly hairs; petioles woolly, with very few gland- 
tipped setze. 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-tipped setze 
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 
setee, falling before the fruit ripens.
