This species occurs in 23 vice-counties, chiefly in North England and Scotland. The leaflets are glandular, nearly hairless or grey-downy, the bracts vinous-red. The leafstalk has biternate prickles. The fruiting sepals are narrowly egg-shaped, lance-shaped, or pinnate, nearly erect, the stalks and fruit densely bristly. Otherwise it resembles R. mollissima, Willd. ( = R. tomentosa, Sm.), of which it was regarded as a variety.
Theprincipalprickles of this species are large, sickle-like. The leaflets are broadly elliptical, glandular. The sepals are erect to spreading. The flower-stalks are hairy, glandular. The fruit is globular. The plant is in other respects like R. tomentosa, Sm., of which it was regarded as a variety.
The thorns of this rose are uncinate, hooked, and stout. The leaflets are hairy both sides, and glandular. The flower-stalks are bristly. The fruit is pear-shaped. The plant is allied to R. tomentosa, Sm., of which it was regarded as a variety.
The prickles of this species are straight, awl-like. The leaflets are variable in shape, nearly hairless above, hairy principally and only thinly so on the veins below, rough to the touch, and sparingly glandular, or without glands, greener below, large, oblong. The sepals are turned back or rising. The fruit is egg-shaped, oblong, aciculate. The style is hairless. The plant is allied to R. tomentosa, Sm., of which it has been regarded as a variety.
The habitat of this species is hedges and thickets. The stem is erect. The branches are arching, long, 6-10 ft., the prickles uniform, straight, slightly curved, slender. The leaflets are elliptic, or rather inversely egg-shaped, doubly-toothed, downy, especially below. The flowers are 1-3, white or pink, on long stalks. The sepals are pinnate, not quite persistent, falling as soon as the fruit changes colour, spreading. The fruit does not soon ripen, being bright-red in September, and is oblong, with a distinct but small disk, pitcher-shaped with a narrow mouth. The plant is 3-8 ft. high, flowering in June and July, and is a deciduous shrub.
This species has the leaflets densely grey - downy, glandular below, with compound teeth. The flower-stalk is short and naked. The fruit is naked. The styles are woolly. The plant has been regarded as a variety of R. mollissima, Willd., but Major Wolley-Dod does not consider the plant typical in Britain at any rate.
This rose is a bush, 4-5 ft. high, with branches with bluish-green powder. The prickles are straight, swollen below. The leaflets are hairy both sides, simply toothed, egg-shaped, acute, the leaf-stalks glandless, grey-downy (hence cinerascens), softly hairy, without prickles. The flowers are few, rose colour, the stalks glandular, hairy. The sepals are spreading, persistent till the fruit is ripe. The fruit is red, nearly globular, egg-shaped, aciculate or smooth. The styles are hairy.
