 doubly glandular-serrate, pubescent beneath or on 

 both sides, often glandular, J^-l^ in. long: fls. on 

 slender, usually smooth pedicels, over 1 in. across, few

 cola, Greene, not H. 

 Braun). Low shrub,

 prickly, usually 

 green: Ifts. 7-11, 

 broadly elliptic to 

 obovate-oblong, 

 acute or obtuse, 

 cuneate at the base,

Mn. 3:116. W.R. 105. Adapted for dry slopes and 

 barren places. Var. alba, Rehd. With white fls. about 

 2 in. across. R. pratincola has been confused with R. 

 arkansana and is sometimes cult, under the latter name. 

 The true R. arkansana, Porter, differs in its glabrous 

 foliage, glandular and bristly stipules, and reflexed 

 sepals; it is known only from Colo. 



44. setipoda, Hemsl. & Wilson (#. macrophylla var. 

 crdsse-aculeata, Vilm.). Shrub, to 10 ft.: branches with 

 paired straight, wide-based prickles: Ivs. 2^-7 in. 

 long; Ifts. 7-9, elliptic or ovate, obtuse or acutish, ser- 

 rate or doubly serrate, dark green and glabrous above, 

 glaucous beneath and puberulous on the veins, l%-2 l /i 

 in. long: fls. about 2 in. across, pale pink, in loose 

 corymbs; pedicel and receptacle copiously glandular- 

 hispid; sepals ovate-lanceolate, long-caudate with 

 foliaceous serrate tips: fr. oblong-ovoid with narrow 

 neck, about 1 in. long, deep red. June. Cent. China. 

 B.M. 8569. J.H.S. 27:486. This handsome rose has 

 proved fairly hardy at the Arnold Arboretum and is 

 very showy in June with its ample clusters of large pink 



3453. Rosa acicularis var. 

 Bourgeauiana (XYz). No. 40. 



fls. and again in fall with the nodding clusters of deep 

 red hips. 



45. macrophylla, Lindl. Large, upright shrub: 

 flowering branches with few prickles or unarmed: Ifts. 

 9-11, elliptic-ovate to elliptic-oblong, acute, simply 

 serrate, glabrous above, pubescent beneath, 1-2 in. 

 long; stipules glandular-ciliate: fls. 1-3, red, about 2 

 in. across; pedicels and receptacle glandular-setose or 

 naked; sepals lanceolate, long-caudate, entire: fr. 

 oblong-ovoid, red, 1-1 M in. long. Himalayas. W.R. 

 50. This species is tender and rarely cult., but several 

 of the allied Chinese species when first intro. were dis- 

 tributed as R. macrophylla or varieties of R. macro- 

 phylla, such as R. Moyesii, R. setipoda, R. Davidii, R. 

 sertata, R. persetosa (see suppl. list for the last three 

 species) ; to R. persetosa belong R. macrovhylla var. 



acicularis, Vilm., 

 and R. macrophyllq 

 f. gracilis, Vilm., 

 while /. gracilis, 

 Focke, belongs 

 partly to R. sertata 

 and partly to R. 

 Moyesii. 



46. Moyesii, 

 Hemsl. & Wilson 

 (R. macrophylla var. 

 rub ro-staminea, 

 Vilm. R. Fargesii, 

 Hort.). Shrub, to 10 

 ft. : branches with 

 scattered short 

 straight prickles: 

 Ifts. 7-13, nearly 

 sessile,ovate or ellip- 

 tic to ovate -oblong 

 or sometimes nearly 

 orbicular, closely 

 serrulate, glabrous 

 except the slightly 

 pilose midrib be- 

 neath, M~l/4 in. 

 long; rachis puberu- 

 lous, glandular and bristly; stipules wide, glandular-cili- 

 ate: fls. solitary or 2, deep blood-red, 1M~2^ in. across; 

 pedicels short, stipitate-glandular like the receptacle, or 

 the latter glabrous; sepals are ovate, abruptly long-cau- 

 date: fruit deep orange-red, oblong-ovoid, narrowed into 

 a neck, 2-2 K in. long. June. W. China. B.M. 8338. 

 J.H.S. 27:489. V.F. 95. G. 37:427. Gn. 72, p. 313. 

 J.H. 111.56:587. G.M. 51:478. A strikingly beautiful 

 rose; its fls. vary considerably in color, from dark 

 blood-red, the color of the typical form, through deep 

 rose to light pink. The extreme light pink form has 

 been distinguished as/, rbsea, Rehd. & Wilson. 



47. gymnocarpa, Nutt. Sts. slender, attaining 10 ft., 

 with straight slender prickles and bristles: Ifts. 5-9, 

 broadly elliptic to oblong, doubly glandular-serrate, usu- 

 ally glabrous, J^-l in. long: fls. solitary on short lateral 

 branchlets, pale pink, about 1 in. across; sepals short: fr. 

 orange-red, globose, small ; calyx drops before maturity. 

 June, July. Brit. Col. to Calif., east to Mont. W.R. 71. 



48. Wfllmottiae, Hemsl. Densely branched shrub, 

 5-10 ft., nearly glabrous: branches with slender paired 

 prickles: Ivs. crowded, %-lM in. long; Ifts. usually 7, 

 elliptic to obovate or sometimes nearly orbicular, usually 

 rounded at the apex, closely and nearly doubly serrate, 

 J^-^in. long: fls. rose-purple, 1-1 J^ in. across, soli- 

 tary, short-stalked, on short lateral branchlets; sepals 

 lanceolate, caudate: fr. subglobose, J^-J^in. long, 

 bright orange-red; the calyx tardily falling off at 

 maturity. May, June. W. China. B.M. 8186. Very 

 pretty rose, not to be confused with R. Willmottiana, 

 L6veille, which is R. longicuspis (see suppl. list), nor 

 with R. blanda var. Willmottiae, Baker.
