PART III. 



Godefroy Cat. ; R. a. multiplex Set: ; R. mixta Tratt. Iios., 1. p. 136. ; is a very hand- 

 some variety with double red flowers and glaucescent leaves ; the stem and branches are 

 almost unarmed ; the peduncles are hispid ; and the sepals are dilated at their apex. 



a 81. 7?. sua v vis Willd. The sweet Rose.

Spec. Char., &;c. Stem hispid. Leaves glabrous, glaucescent beneath. 

 Peduncles and petioles clothed with glandular bristles. {Don's Mill , ii. 

 p. 567.) Petals deep purple, deeply 2-lobed. Fruit oblong, glabrous. 

 Cultivated in 1818 ; growing to the height of 3 ft. or 4 ft, and flowering 

 in June and July. This very distinct variety, or perhaps species, of 

 rose is probably at present wanting in British collections ; for it must 

 not be confounded with i?bsa suaveolens or with .Kosa suavifblia, 

 both described in Le Botaniste Cultivateur as varieties of R. rubigi- 

 nbsa, or synonymes to that species. The genus Rbsa. is, indeed, liable 

 to such extreme variation, that it would not surprise us in the least 

 to be informed that R. suavis (Jig. 484.) is also a variety of R. rubi- 

 ginbsa. It is not known of what country R. suavis is anative ; and 

 this circumstance renders it not improbable that it may be a garden 

 production. 



& 22. R. acicula v ris Lindl. The needle-prick led Rose.

Engraving. Lindl. Ros., t. 8. 



Spec. Char., #c. Tall. Prickles acicular, unequal. Leaflets glaucous, wrinkled, rather convex. 



Fruit rather flask-shaped, drooping. (Don's Mill., ii. p. 567.) Flowers solitary, pale blush, fragrant. 



Fruit obovate, naked, of a yellowish orange colour. Native of Siberia. Introduced in 1805 ; 



growing to the height of from 6 ft. to 8 ft., and flowering in May and June.

Spec. Char., Sec. Prickles of branches crowded, unequal, slen- 

 der, reflexed ; of the branchlets, small and nearly equal. 

 Leaflets flat, glabrous, simply serrated. (Don's Mil/., ii. 

 p. 568.) Flowers pale yellow. Fruit large, ovate, black. 

 Native of North America and Siberia. Introduced in 1780; 

 growing to the height of from 4 ft. to 6 ft., and flowering in 

 May and June. It forms a very distinct variety, or probably 

 species, and, on that account, is well deserving a place in 

 botanical collections. 



Sfe 24. R. sulphu v rea Ait. The sulphur-coloured-Jlowered Rose.

Spec. Char., fyc. Stipules linear, divaricate, 

 dilated at the apex. Leaflets glaucous, flat- 

 tish. Tube hemispherical. (Don's Mill., ii. 

 p. 568.) Stem prickles unequal, scattered. 

 Flowers large, of a fine transparent yellow, 

 always double. Native of the Levant. In- 

 troduced before 1629 ; growing to the height 

 of from 4 ft. to 10 ft., and flowering in July. 

 This sort does not flower freely, except in 

 open airy situations ; and, if trained against 

 a wall, exposed to the north or east rather 

 than to the south. Its flower buds are apt 

 to burst on one side before they expand, 

 and consequently to become deformed ; to 

 prevent this, the blossom buds should be 

 thinned, and care taken that they have 

 abundance of light and air. Watering it 

 freely in the flowering season is also found 

 advantageous; and the shoots, in general,
