126 ROSE FAMILY. 



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



§ 1. Wild Roses of the country : only the first species 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-tube, 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 

 hip glandular-bristly. 



R. Iticida, 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. bl^nda. Early Wild Rose. Rocky banks N. : 10-3° high, with 

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

 sometimes hoary beneath, large stipules, 1 - 3-flowered ])eduncles and the calyx 

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



§ 2. Briek-Roses, naturalized from Europe, by roadsides and in thickets, or 

 sometimes planted : fioioering 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. micr^ntha. Small S. Probably a mere variety of the common Sweet- 

 Brier, with uniform hooked prickles, smaller flower, and more oblong or oval 

 hip, from which the calyx-lobes fall early. 



R. canlna. Dog Rose. Roadsides E. Penn. and probably elsewhere: 

 resembles Sweet-Brier, but the leaflets sfnooth 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 : 

 fiowering in spring, the fiowers not double. 



R. Sinica (or l^vigXta), 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. bracte&;ta, 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. Seinp6r'viren8, 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.
