R. SERTATA, Rolfe. 

 t. Mag., t. 8473.) 



A shrub of elegant habit, up to 5 ft. (perhaps more) high ; branches 

 glaucous, graceful and slender, armed with spines up to ^ in. long, in pairs or 

 scattered. Leaves 2 to 4 ins. long, composed of seven to eleven leaflets, 

 which are stalkless, oval to oblong, sharply toothed ; ^ to f in. long, ^ to 

 in. wide ; grey-green above, glaucous beneath ; stipules edged with 

 glandular hairs. Flowers few or solitary on short twigs, 2 to 2.\ ins. across ; 

 flower-stalk f to i|- ins. long, glandular-hairy or smooth ; petals broadly 

 obcordate, delicate purplish rose ; calyx-lobes ovate-lanceolate, tapering to 

 a long, narrow point, minutely downy, sometimes glandular-downy, some- 

 times smooth ; anthers deep yellow. Fruit deep red, egg-shaped, f in. long, 

 the sepals persisting at the top. 



Native of Central China ; introduced by Wilson in 1907, and flowered at 

 Kew in June 1910. It is an extremely elegant and pretty rose, allied to 

 R. Webbiana and R. Willmottiae. From the former of these it differs " in its 

 laxer habit, its few, slender, straight, stipulary thorns, and its more slender, 

 beaked fruit. R. Willmottiae has smaller leaves and short-stalked flowers 



R. SETIGERA, Michaux. PRAIRIE ROSE. 



(R. rubifolia, R. Brown.) 



A rambling shrub making slender stems several yards long in a season, 

 armed with short, hooked prickles, not downy. Leaves trifoliolate, with a 

 downy, glandular stalk and narrow stipules edged with glands. Leaflets 

 among the largest in the genus, up to 3 ins. long by over 2 ins. wide ; ovate, 

 coarsely toothed, deep green and smooth above, pale and downy beneath. 

 Flowers 2 to 2^- ins. across, deep, rose, numerous in corymbs ;- the stalk 

 glandular. Sepals ovate, pointed, ^ in. long, very downy. Fruit globose, 

 about | in. diameter, with the sepals fallen away. 



Native of E. and Central North America, from Ontario to Florida, ana 

 west to Kansas and Texas. Introduced in 1800. This is the most distinct 

 and, in its flowers, perhaps the most beautiful of N. American roses. It is 

 the only one from that region belonging to the group whose styles are united 

 in a column (Synstylse) ; the only one with normally three leaflets, and the 

 only climbing species. It is an attractive plant, producing its large, rich 

 rosy blossoms in clusters 6 ins. or more across, but they have little or no 

 fragrance. Flowering in July and August when few wild roses or shrubs of 

 any kind are in flower, its value is increased. It may be trained up rough 

 branches of oak, then left to form a tangle. Several garden varieties have 

 been raised from it. 



R. SETIPODA. Hemsley and Wilson. 



A bushy shrub 6 to 10 ft. high ; stems sometimes unarmed, sometimes 

 furnished with few to many straight, stout spines. Leaves 4 to 7 ins. 

 long, composed of five to nine leaflets, which are oval, obovate, or 

 ovate ; f to 2^ ins. long, half or more than half as wide ; tapering towards 

 both ends, simply or very frequently doubly toothed ; dark green and 

 smooth above, pale, rather glaucous, usually covered with glands beneath, 

 and downy on the midrib ; common stalk usually more or less glandular and 

 prickly. Flowers purplish rose, 2 to 2^ ins. across, produced in loose terminal 

 corymbs of from over thirty down to half a dozen blossoms. Each flower is
