This handsome Single Rose is supposed to be one of the varieties of the Carolina, and for that reason, we believe, called the Pennsylvanian Rose, and perfectly well known under that title; although we think the plant bears very little affinity to the Carolina Rose, and is perhaps nearer allied to the Austrian than any other. It certainly bears a considerable resemblance to the Burnet-leaved variety of the Carolina; but has much more of the character of a brier attached to it, and is generally estimated as the most desirable variety. It is in fine bloom from the middle of June to the end of August. There is a delicate variety of it with double flowers. Our figure was made from the nursery of Messrs. Colville. [Illustration] ROSA parvifolia. _Small-leaved, or Burgundy Rose._ CHARACTER SPECIFICUS. ROSA, germinibus globosis; pedunculis et petiolis hispidis; floribus multiplicibus, equalibus; foliolis ovatis, acutis, parvis, subtus villosis, marginibus serrulatis; caule fruticoso; aculeis ramorum sparsis, rectis. SPECIFIC CHARACTER. ROSE, with round seed-buds; peduncles and petioles hispid; flowers with many folds, and equal; leaflets ovate, sharp-pointed and small, hairy beneath, with finely sawed edges; stem shrubby; the spines of the branches are scattered and straight. * * * * * This beautiful Dwarf Rose is certainly a very distinct species, and generally known by the appellation of Burgundy Rose. It is an early-blooming Rose, and makes a brilliant appearance. The flowers are very double, of a rich red purple when in perfection, but of a paler or bluer colour when retiring. It is very easily distinguished from any other dwarf Rose, by the striking resemblance which it bears to the Ranunculus, and from which a good specific name might have been derived, had not the leaves (ever the most appropriate characteristic) furnished an unexceptionable title, recently adopted by professor Willdenow in his Species Plantarum. Our drawing was made from fine plants at the nursery of Messrs. Whitley and Brames. [Illustration] ROSA spinosissima. _Thorny Rose._ CHARACTER SPECIFICUS. ROSA, germinibus globosis, glabris; pedunculis et petiolis glabris; foliolis ovatis, crenatis, glabris; floribus albis; caule et ramis aculeatissimis; aculeis rectis, sub-albidis. SPECIFIC CHARACTER. ROSE, with smooth round seed-buds; peduncles and petioles of the leaf smooth; the leaflets are egg-shaped, notched, and smooth; flowers white; the stem and branches are very prickly; the prickles straight, and nearly white. * * * * *
