R. sertata is a species Wilson met with several times, from 1901 to 1910 during his four trips to China. Pink or rose in color, its petals are emarginate (a notch in the petals). The flowers bloom in small clusters, and the reddish canes boast a few straight prickles. Upright and arching, this China rose may be an extreme form of R. webbiana found in Tibet, Afghanistan, and the Himalayas.

R. hwangshanensis, according to the Botanical Garden Berlin-Dahlem, originates from China, province Anhuei, from the Huanshan mountains. She belongs without doubt to the Cinnamomea-series, in a group together with R. caudata, R. banksiopsis, R. macrophylla, R. setipoda, R. hemsleyana, R. sweginzowii, R. giraldii, R. prattii and R. multibracteata.

Webbiana has small delicately-cut leaves of a glaucous shade with soft pinkish-red stipules, and the newer sertata, I believe, makes a bush of similar appearance.

Rosa (§ Cinnamomeae) sertata, Rolfe; species ex affinitate R. Webbianae, Wall., a qua habitu laxiori, aculeis tenuioribus, foliis longioribus et fructu angustiori differt.

The handsome Rose here figured is one grown from Chinese seeds obtained by Mr. E. H. Wilson on behalf of Messrs. J. Veitch and Sons, which flowered in the Kew collection in June 1910. The flowers show that it is identical with another plant collected by Mr. A. Henry, which the late Professor Crepin thought might be a small-leaved form of R. macrophylla, Lindl., and with two other Chinese plants presented by Messrs. Vilmorin, Andrieux, as R. Webbiana, Wall. Neither of the suggestions hitherto offered is, however, wholly satisfactory. From R. macrophylla the species here described as R. sertata differs in its much smaller rounded leaflets and in numerous other details ; from R. Webbiana it is easily distinguished by its laxer habit, its few slender straight stipulary thorns, and its more slender, beaked fruit. It is more nearly allied to R. Willmottiae, Hemsl., a plant figured at t. 8 1 8(5 of this work, than it is to R. Webbiana, but R. Willmottiae is a much smaller plant in all its parts than the subject of our plate. In gardens R. sertata will be valued for its graceful habit; it makes long slender shoots which in the following season become gracefully arched and bear in mid- June a profusion of its beautiful flowers followed by richly coloured fruits, while it has the finely cut, daintily formed leaves and the glaucous stems that have rendered its allies R. Webbiana and R. Willmottiae such favourites among wild roses. It has so far succeeded well in stiff loam and gives promise of being a more vigorous shrub in gardens than R. Webbiana. So far the only experience of its propagation has been from seed, but it is probable that, like R. Webbiana, it may be increased by layers and perhaps by autumn cuttings.

Description. — Shrub, branched, 3-5 ft. high ; twigs glaucous, armed with straight, slender, geminate prickles over 1/3 in. long, rarely unarmed. Leaves clustered, 1 3/4-4 in. long, 7-11-foliolate, rachis sparingly glandular-setulose and prickly ; leaflets subsessile, elliptic or elliptic-oblong, obtuse, sharply toothed, glaucous beneath, 1/3-3/4 in. long, stipules adnate, narrow-oblong, acute or somewhat blunt, ciliate-glandular, 1/3 in. long. Flowers showy, rose or rose-purple, 2-2 1/4 in. across, few or solitary at the ends of abbreviated twigs; peduncles 2/3-1 1/4 in. long, glandular-setulose or smooth. Receptacle narrow-ovoid, glandular-setulose or smooth, 1/5-1/3 in. long. Calyx lobes ovate-lanceolate, caudate-acuminate, sometimes leafy, puberulous, glandular-setulose or smooth, 1/3-3/4 in. long, somewhat spreading. Petals wide-obcordate. Filaments glabrous, 1/8-1/5 in. long; anthers golden-yellow. Fruit ovoid, narrowed at the top, deep red, about 3/4 in. long, crowned by the persistent sepals. Achenes villous at the base and on the back, 1/8 in. long ; styles villous, cohering in a column 1/6 in. long.
