The Musk Roses of china and India and that of the high mountains of Persia, R. moschata var. nastarana Christ (R. Pissardi Carrière), distinguished at a glance by their larger leaves, much more numerous flowers in large rounded or paniculate corymbs, were unknown to botanists and to western gardens in Miller's time [1768]. In the latter half of the 19th century Crépin and other botanists believed that the range of Miller's R. moschata extended through Persian and northern India to the extreme east coast of China. Most of them admitted that the new forms discovered differed, however, from their conception of the original Musk Rose, and gave them varietal names. Our study, however, of this perplexing subject has convinced us of two thing: -(1)That the Musk Rose of Miller is little if at all different from Rosa ruscinonensis Grenier and Déséglise....and from R. abyssincia R. Brown, and their intermediate forms; (2) that the Musk Roses of India and China are distinct from those known to Miller and his predecessors and that they are best considered geographical segregates under separate names since they display constant characters sufficient to distinguish them as species...
The Rose figured by Miss Willmott (Gen.Rosa, I. 33, t. [1910]) as R. moschata Miller is a form of R. Brunnonii Lindley. Since this....is superior as a garden plant to the old Musk Rose, it has very generally supplanted it and it is doubtful if R. moschata Miller is now in general cultivation.

Rosa banksiae var. normalis Regel
This rose is very abundant in western Hupeh and eastern Szechuan from river level to 1000 m. alt....It delights in glens, ravines and rocky places generally, where it forms tangled masses 6 m. and more high and as much in diameter; commonly it rambles over trees and Wilson has seen trees 15 m. and more tall completely festooned with this Rose. The flowers are always pure white, and we have never observed any tendency towards double flowers in the wild plant; nor did Wilson see it or any of its foms cultivated in gardens in central or western China.

Shansi : mountains in northwest, April 1910, W. Purdom (No. 314, seeds only).
Cultivated at the Arnold Arboretum; plants raised from Purdom's No. 314: June 17 and Aug. 26, 1914, June 1915 (type).
This pretty Rose seems most closely related to R. Moyesii Hemsley & Wilson, which is a much more vigorous plant with stout prickles, larger usually more acute leaflets pubescent beneath, at leaat on the midrib, globose-ovoid flower-buds abruptly contracted at the apex, larger flowers and pinnate sepals. It may also be compared with R. Sweginzowii Koehne. which differs chiefly in its stouter much flattened prickles, the usually doubly serrate leaflets more or less pubescent beneath, in the globose-ovoid flower-buds and in the pinnate sepals.

Rosa bella, f. pallens Rehder & Wilson, f. n.
A typo recedit floribus pallide roseis.
Shansi : mountains in northwest, April 1910, W. Purdom (No. 314, seeds only, in part). Cultivated at the Arnold Arboretum; plants raised from Purdom's No. 314, together with those of the type; June 1915, type.
Though this form differs from the type in the pale color of the flowers only, it seems desirable to distinguish it for horticultural purposes, as both forms are in cultivation.

Rosa chinensis f. spontanea Rehder & Wilson
This Rose is common in wayside thickets and on the banks of rivers in Shihch'uan, but rare elsewhere so far as known. Our specimens are in fruit only, but they agree exactly with Henry's; and we think that Henry is right in considering this plant to be the wild type of Rosa chinensis Jacquin. The Rosa lucidissima Léveillé ...appears to us to be nothing but a state of this forma spontanea distinguished only by its leaves being pale green on the underside and not glaucescent and by the calyx-tube being densely covered with stipitate glands [glands that are elevated on a stalk].

Note: The plant described by Rolfe was raised from seed Wilson had collected. But there is a contradiction: Wilson described the styles as more-or-less exserted and free, whereas Rolfe wrote, "styli villosi, in columnam 4 mm. longam cohaerentes", hairy styles  in a coherent column.

Rosa Davidii Crépin
It is a common Rose on the mountains of western Szech'uan, in Mupin, where David collected it. It is the species in China nearest to R. macrophylla Lindley [note below] of the western Himalaya. Lindley's plant differs in its more acute leaflets with more acute serratures, which are more hairy on the under side and in its short styles.
[Note] The different botanists who have dealt with the Roses of the interior of China have referred many specimens to Rosa macrophylla Lindley, but in nearly every case have made them varieties or forms, or have remarked that the specimens differ in aspect from Lindley's type. Whether or not the real R. macrophylla Lindley occurs in China is problematical, but certainly its nearest ally is the Rose we refer to R. Davidii Crépin.

Rosa Davidii, var. elongata Rehder & Wilson...Western Szechuan...bush 3-5 m., flower rose-pink, fruit scarlet to orange-red)). This variety is distinguished from the type by its fewer flowers, its larger more elongated fruit and by its usually larger leaflets, which vary from nearly glabrous to silkily pubescent on the under side. In No. 1114 the leaves are pubescent on both surfaces, but seedling plants raised from this number are normal in their pubescence.

Rosa filipes Rehder & E. H. Wilson
climbing, 3-6 meters, leaves with 3-9, mostly 5-7 leaflets, margins minutes biserrate; the margins with a few glands, upper surface intense green, glabrous, lower surface pale, with minute brown glands on stalks. Stipules adnate, narrow, auricles narrow. White fragrant flowers in numerous terminal corymbs with filiform pedicels.
This species is very distinct from the other member of this group [this species is described with other species of the section Synstylae] and is well characterized by its glabrous shoots and leaflets which are gland-dotted on the under-side, by its very large paniculate inflorescence of moderately large flowers on filiform pedicels and by its small globose fruit covered with bloom.... It may be compared with R. Brunonii Lindley, which, however, is a pubescent plant, with narrower leaflets, larger flowers in much smaller and shorter paniculate corymbs.

Rosa Helenae Rehder & Wilson, n. sp. ...
R. Gentiliana Léveillé & Vaniot differs in its glabrous, 5-foliolate leaves, which are glaucescent below and have larger more coarsely toothed leaflets, and in its gray stems and globose fruit.
