This species is well distinguished by its glabrous shoots which become pale gray with age, by its glabrous 3-5-foliolate leaves which are shining green above, glaucescent and very pallid on the underside, with relatively broad, coarsely serrate long acuminate leaflets occasionally abruptly rounded with a short acumen. The flowers are very numerous in flattened or rounded corymbs; the fruit is small and globose. Rosa Gentiliana is abundant in the mountainous region of western Hupeh and eastern Szech'uan which would appear to mark its western limits of distribution. It is partial to rocky places from river-level to 1400 m. altitude, forming tangled masses 6 m. and more tall. The flowers are large, very fragrant, and their beauty is increased by the golden-yellow anthers. Léveillé describes the styles as "free" in his Rosa adenoclada, but this is incorrect. Miss Willmott states that R. adenoclada Léveillé is near R. lucidissima Léveillé, but we consider the last named to be only a state of the very different R. chinensis, f . spontanea Rehder & Wilson. It is probable that Rosa moschata, var. densa M. de Vilmorin (in Jour. Hort. Soc. Lond. XXVll. 482, fig. 134 [1902]) should be referred to R. Gentiliana Léveillé, although it is not stated whether the shoots and leaves are glabrous or pubescent.
A picture of this plant will be found under No. 060 of the collection of Wilson's photographs.

The narrower and smaller more or less curved leaflets and fewer-flowered corymbs serve to distinguish this variety. Had we more material other differences might be apparent. It is possible that the Rosa alba Loureiro (Fl. Cochin. 323 [1790]) belongs here.

Description in Latin. Enjoy.
This very distinct species readily distinguished by its large leaflets with strong...venation [pattern of veins] and villose pubscence [long hairy downy surface] on the underside, by its large ...stipules, by its short-peduncled dense corymbs...
It is related to Rosa longicuspis which is nearly glabrous [smooth] everywhere and has shining green leaves with much less prominent venation, flowers on longer pedicels, and a very much larger red or scarlet fruit. This new species has a rather local distribution.

This handsome Rose is abundant in the thickets and on the margin of woods in the regions east of Tachien-lu, where the type is common. With its large pale pink flowers and large leaves this form looks very distinct from the type.

This is a very common species in the mountain thickets of extreme western Szech'uan between 2000 and 4000 m. altitude. The flowers vary considerably in color, and the pedicels and calyx-tube are smooth or densely stipitate-glandular. The typical form, which has dark red flowers, is abundant in the upland thickets round Tachien-lu and is one of the most beautiful of Roses. This species is closely related to a Rose found in the Sikkim Himalaya at 3300 m. alt. and which we think may be R. Hoffmeisteri Klotzsch. However, until the flora of the regions between western Szech'uan and Sikkim is known it appears to us best to consider them distinct species. M. de Vilmorin's Rosa macrophylla, var. rubrostaminea (in Jour. Hort. Soc. Land. XXVII. 490, fig. 139 [1902-03]) is doubtless referable to one of the numerous color forms of Rosa Moyesii, or to the following variety. [Rosa Moyesii f. rosea]

This is a very common Rose growing in sandy and rocky places beside streams everywhere in western Hupeh and in Szech'uan from river-level to 1300 M. altitude. The flowers are always pink and larger than those of the type [R. multiflora], and like the type it is a variable plant. The stems may be prostrate or erect; the leaves vary extremely in size, and the leaflets vary from narrow-leanceolate to suborbicular and are nearly glabrous or very pubescent. The stipules vary in size and in degree of lacination, and the pedicels are smooth or densely stipitate-glandular.
The typical R. multiflora Thunberg is a native of Japan and has pure white smaller and usually more numerous flowers in the clusters. Rosa multiflora, var. cathayensis is the wild parent of the double pink forms enumerated below and introduced into England from China in 1804 and 1816, while the Japanese Rosa multiflora was not introduced until sometime about 1860. The first mention of this variety is found in Plukenet (Amalth. 185 [1705]) under the name " Rosa sylvestris cheusanica, foliis subtus incanis, floribus purpureis parvis."
A picture of this Rose will be found under Nos. 014, 019 of the collection of Wilson's photographs.

Rosa multiflora var. carnea Thory in Redouté, and
Rosa multiflora var. carnea f. platyphylla "Seven Sisters"]

This form differs from [Rosa odorata var. gigantea] in its pale pink often somewhat smaller flowers.

Rosa odorata var. gigantea Rehder & Wilson
This variety is the wild form of the Tea Rose; it is widely dispersed in Southern Yunnan and has been reported from Mengtsze in the east to the frontiers of the Shan States in the extreme southwest. The flowers vary from white to yellow or pale buff or to pale pink and are delightfully fragrant. In tall thickets and margins of woods it is a tall and rampant climber, but on the open plateaus it forms a bush with arching stems and is often not more than 2 m. tall.

Shrubs .5 - 1 m. tall, flowers rosy-red, fruit yellowish.
This bush Rose is abundant by waysides and in semi-arid river-valleys throughout the warmer parts of western Szech'uan....it is commonly used as a hedge-plant. ...It's ...leaflets and less sharply acute serratures and the absence of pubescence distinguish it from the Japanese R. Roxburghii var. hirtula Rehder & Wilson.

Rosa Roxburghii var. hirtula Rehder & Wilson
[described primarily for its distinctions from R. roxburghii f. normalis, which has single flowers but lacks pubescence on the foliage]:
Its [R. Roxburghii f. normalis] ...leaflets and less sharply acute serratures and the absence of pubescence distinguish it from the Japanese R. Roxburghii var. hirtula Rehder & Wilson...It is this Japanese variety with single flowers which is in cultivation and which is figured by Hooker f. as R. microphylla... This var. hirtula is spontaneous in central Hondo, and Wilson has collected it at 1000 m alt. on the northern slopes of Fuji-san, Japan.
