ARBORETUM AND FRUTICETUM. 



PART 111. 



Godefroy Cat.; R. a. multiplex Set: ; R mfxta Tratt. Ros., 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.

Spec. Char., SfC. Stem hispid. Leaves glabrous, glaucescent beneath. 

 Peduncles and petioles clothed with glandular bristles. {Don's ^fi// , ii. 

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

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

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

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

 not be confounded with /?bsa suaveolens or with Rbsa suavifbli.i, 

 both described in Le Rotaniste Cttltivatrur as varieties of R. rubigi. 

 nbsa, or synoiiynies to that species. The genus /{osa is, indeed, liable 

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

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

 ginbsa. It is not known of what country R. suJivis is a native ; and 

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

 production.

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

Spec. Char., c^-c. Prickles of branches crowded, unetjual, slcn 

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

 Leaflets flat, glabrous, simply serrated, (Don^s Mill., 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 G ft., and flowering in 

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

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

 botanical collections.

Spec. Char., Sfc. Stipules linear, divaricate, 

 dilated at the apex. Leaflets glaucous, flat- 

 tish. Tube hemispherical. {Do)i'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 aga'nst 

 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.
