(R. dumeto'rum. Fruit elliptical, smooth, as tall as the bracteas: 
flower-stalks aggregate, slightly hairy : calyx copiously pinnate, 
somewhat cut: prickles numerously scattered, hooked: leafits 
simply serrated, hairy on both sides. 
Four to six feet high, with many weak spreading branches. Petals reddish. 
Styles prominent, a little hairy. Fruit red, ovate. Sm. Calyx long, per¬ 
manent on the fruit: no doubt can exist of its being distinct from every 
other British species. Like R. canina, it frequently throws out strong 
leading shoots, which soon overtop the bunches of flowers. Winch.*' 
Thicket Rose. R. dumetorum. Woods. Sm. Winch. So nearly re¬ 
sembling R. Borreri, of Woods, which is R. dumetorum, E. Bot. 2579, 
that Hooker and others unite them under R. rubiginosa ; the var. inodora 
of which (Lindl. p. 88.) is represented in FI. Lond. 117. In hedges in 
the southern counties. In Heaton Wood, near Newcastle on Tyne ; and 
hedges near Sandyford, Northumberland. Mr. Winch. J. June. E.) 
(R. glaucophyi/la. Calyx permanent: fruit egg-shaped, smooth: 
leafits egg-shaped, doubly serrated, glaucous : prickles hooked. 
This is a much slenderer, though less trailing briar than R. canina; its 
Jlowers are pale pink, growing in pairs or single, and its fruit large. 
It also further differs in habit, by not having young shoots sprouting 
beyond the blossoms, so as to give them the appearance of being axillary : 
and from R. sentriosa of Acharius, (Stockh. Tr.) in the fruit being 
ovate ; not globular. It also resembles R. ccesia, E. Bot. 2367, in many 
points, but differs in having smooth, not downy leaves ; glaucous espe¬ 
cially in spring. It may probably have been often overlooked as a 
variety of R. canina. Winch.

(R. CiE'siA. Fruit roundish-ovate, smooth : prickles of the stem hooked : 
leafits egg-shaped, pointed, doubly serrated, downy : very glau¬ 
cous, as well as the germen and young branches. 
E. Bot. 2367. 
Flowers most frequently solitary, sometimes in pairs. Fruit varies from 
oblong to nearly globose. It differs from R. canina in its downy leaves, 
and their very glaucous hue. E. Bot. Hooker has included it under that 
species; as also R. dumetorum of Woods, (not of E. Bot.)

unsophisticated productions of nature, it were unreasonably fastidious not to concede a 
single note of admiration to the triumph of floriculture. The most splendid and compre-
