†R. cathayensis, n. st. (R. multiflora, Thunb., var. cathayensis, Rehd. & Wils. in Sergent, Pl. Wilson. ii, 304). A. R. multiflora differt foliolis plerisque majoribus et magis acuminatis (vel saltem non obtusis), saepius quam in illa specie 2-jugis, floribus pauciori.. bus et majoribus 3-5 cm. diam. corymbosis potius quam paniculatis roseis, pedicellis longioribus et saepe glandulosissimis.
 
Shanghai cult. Kuling. Chi-kung-shan(4). common wild plant in the Chi-kung-shan country: fls. rose-color or rose-pink, 1 1/2  to 2 in. across; bush sometimes erect, sometimes weak and prostrate, apparently a smaller and weaker plant, as a rule, than R. multiflora. By this separation, the pink-flowered plant of China becomes a distinct species from the Japanese white-flowered smaller-leaved fragrant very floriferous rose, and this disposition, if accepted, will change the nomenclature of some of the cultivated roses. Whether the lines of separation between the two are always clearly marked. I do not know; but being familiar with the usual white-flowered Rosa multiflora (the Rosa polyantha of horticulturists) I was struck with the unlikeness al the Chinese plant when I found it in the wild. R. multiflora itself is in cultivation at Shanghai, in characteristic form. I am convinced that the separation, so well begun by Rehder and Wilson, is necessary to an understanding of these two roses. The Chinese plant is prevailingly distinguished by the larger and more acuminate-pointed leaflets, the larger and colored flowers which are in few-flowered more open clusters. R. multiflora is typically characterized by its many small flowers in a long duster or panicle.

†R. cathayensis var. exigua, var. nov. Frutex humilis, tenuis; foliola parva et angusta, 3-4 cm. longs et 1-1.5 cm. lata; stipulae valde pectinatae.—Chi-kung-shan, and perhaps also a poor specimen from Kiu-kiang, Prov. Kiangsi.
