12G ROSE FAMILY. 



14. ROSA, ROSE. (The ancient Latin name of the Rose.) 



1. WILD ROSES of the. country : only the first secies cultivated. 

 # Styles lightly cohering in a column and projecting out of the calyx-cup. 

 R. setigera, PRAIRIE or CLIMBING WILD ROSE. Rich ground, W. & 

 S. : also planted, and partly the original of QUEEN-OF-THE-PRAIRIE, &c. dou- 

 ble roses. Tall-climbing, armed with stout nearly straight prickles, not bristly ; 

 leaves with only 3-5 ovate acute leaflets ; the corymbed flowers produced 

 towards midsummer ; stalks and calyx glandular ; petals deep rose becoming 

 nearly white. 



* * Styles separate, included in the calyx-tufa, the stigmas closing its orifice: 



petals rose-color : stems not disposed to climb. 



R. Carolina, SWAMP ROSE. Wet grounds: stems 4 -8 high, with 

 hooked prickles and no bristles ; leaflets 5-9, smooth, dull above and pale be- 

 neath; flowers numerous in the corymb (in summer) ; the calyx and globular 

 hipglandular-bristly. 



R. lucida, DWARF WILD ROSE. Dry or moist ground: l-2 high, 

 with bristly or slender straight prickles, 5-9 oblong or almost lanceolate leaf- 

 lets shining above, 1 -3-flowered peduncles, bristly calyx, but the depressed hip 

 nearly smooth : fl. all summer. ' 



R. blanda, EARLY WILD ROSE. Rocky banks N. : l-3 high, with 

 straight weak prickles or none, 5-7 oval or oblong blunt and pale leaflets, 

 sometimes hoary beneath, large stipules, 1 - 3-flowered peduncles and the calyx 

 smooth and glaucous, the hip globular : fl. spring or early summer. 



2. BRIER-ROSES, naturalized from Europe, by roadsides and in thickets, or 

 sometimes planted : flowering in summer. 



R. rubigindsa, SWEET-BRIER. Tall, disposed to climb, armed with 

 strong and hooked and some slender and awl-shaped prickles, the roundish and 

 doubly-serrate small leaflets downy and beset with russet glands beneath, giving 

 the aromatic fragrance ; flowers mostly solitary, pink ; hip pear-shaped or obo- 

 vate, crowned with the calyx-lobes. 



R. micrantha, SMALL S. Probably a mere variety of the common Sweet- 

 Brier, wi*h uniform hooked prickles, smaller flower, and more oblong or oval 

 hip, from which the calyx-lobes fall early. 



R. canina, DOG ROSE. Roadsides E. Penn. and probably elsewhere: 

 resembles Sweet-Brier, but the leaflets smooth or destitute of aromatic glands 

 and simply serrate ; flowers 3 or 4 together, pink or nearly white. 



3. EVERGREEN ROSES, naturalized in the Southern States from China : 

 flowering in spring, the flowers not double. 



R. Sinica (or L^VIGATA), CHEROKEE ROSE. Planted for garden- 

 hedges, &c., also run wild S., disposed to climb high, armed with strong hooked 

 prickles, very smooth, with bright green and glossy evergreen leaves of mostly 

 only 3 leaflets, and single flowers at the end of the branches, with bristly calyx- 

 cup and large pure-white petals. 



R. bracteata, BRACTED ROSE. In hedges far S., not common ; has 

 downy branches armed with strong hooked prickles, 5-9 roundish leaflets, and 

 single large white flowers on very short peduncle, the calyx covered by leafy 

 bracts. 



4. EXOTIC GARDEN ROSES proper, from Europe and Asia. Merely the 

 principal types: the greater part of the modern garden roses too much 

 mixed by crossing and changed by variation to be subjects of botanical study 



* Styles united in a column which projects out of the calyx-cup. All with long 



rambling shoots, or disposed to climb. 



R. Semp6rvirens, EVERGREEN ROSE of S., not hardy nor holding its 

 leaves N., with coriaceous bright-green oblong leaflets, curved prickles, and 

 nearly solitary white flowers, not double. The AYRSHIRE ROSE is a more 

 hardy form of it.
