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.
