large. Peduncles and calyxes tomentose. Fruit 

 globose, large, orange red. (Dec. Prod., ii. p. 602.) 

 Flowers showy, pure white, solitary, nearly ses- 

 sile. Fruit spherical, orange red. Native of China. 

 Introduced by Lord Macartney, in 1795; grow- 

 ing to the height of 5 ft. or 6 ft., and flowering 

 from June to October. A very ornamental shrub, 

 evergreen, with large white flowers, and nu- 

 merous bright yellow stamens and styles. It 

 flowers abundantly, but is rather tender. It suc- 

 ceeds best when trained against a wall.

Spec. Char., Sfc. Stem almost without prickles. Leaf- 

 lets glossy, sharply serrated, veiny beneath, with 

 densely netted, anastomosing veins. Stipules very 

 narrow, unequal. Flowers double, of a delicate rose- 

 colour. Calyx densely invested with prickles. Sepals 

 short, broadly ovate, echinate, ending in a point. 

 Prickles having at the base two longitudinal furrows. 

 {Dec. Prod., ii. p. 602.) Flowers very large, double, 

 and of a delicate blush colour. Native of China. In- 

 troduced in 1828, or before; growing to the height of 2 ft. or 3 ft., and 

 flowering from August to October. An interesting little shrub, but some- 

 what tender, like Ii. bracteata.

Spec. Char., Sfc. Shoots long, tender. Branches pale brown, 

 tomentose, scarcely prickly. Leaflets 3 — 9, elliptical-lanceo. 

 late, tomentose beneath. Stipules hardly atta^ed to the 

 petiole, bristle-like-fringed. Flowers terminal, mostly soli- 

 tary, white. Peduncles and calyxes tomentose. [Dec. Prod., 

 ii. p. 602.) Seringe seems to consider this as a variety of 

 R. bractefita. It is a native of Nepal and China, with 

 white flowers in corymbs, surrounded by three or four 

 approximate leaves. It was introduced in 1818; grows to 

 the height of 3 ft. or 4 ft. ; and flowers in June and July. 

 Plants of this kind, which is very distinct both in its 

 foliage and its flowtrs, are rare in collections. Being some- 

 what tender, it is greatly improved in growth by the pro. 

 tection of a wall, on which it makes a fine appearance. 

 On the rose wall at Messrs Loddiges, three years ago, there 

 was a plant of R involucr^ta, which had attained the height 

 of the wall (11 ft.), and which flowered magnificently.

Sect. Char. Plants setigerous or unarmed, bracteate. Leaflets lanceolate 

 glandless. Disk thin, never thickened. This section is distinguished by- 

 its long lanceolate leaflets, without glands, upright shoots, and compact 

 habit. Red flowers, never solitary, except by abortion, and always sup- 

 ported by bracteas. Round, small, red fruft (soon losing its long narrow
