Somewhat similar in form to R. moyesii is R. sweginzowii, which Wilson introduced to England that same year [1903]. Triangular prickles mix with bristles on the stems, though occasionally some canes are “thornless.” (That calls to mind that wonderful lilac-pink Bourbon rose ‘Charles Lawson’, which also often exhibits both “thornless” and prickled canes on the same bush.) The bright pink flowers with creamcolored stamens are small, two inches in diameter or less, growing solitary, in twos or threes, at times in clusters of about six. Leaflets range from seven to eleven, the foliage similar— according to Wilson—to that of R. moyesii. An attractively ostentatious plant, R. sweginzowii can form an eight to ten foot impenetrable hedge. Wilson found this species “closely related to R. setipoda” and probably merely a geographical variation of the latter.

I have R. Sweginzowii, but so far it has done nothing very remarkable. The fruits have fallen off before they had a chance to ripen. It may be one of those that take a long time to come to maturity.

Rosa sweginzowii Koehne. 
"A tall good bush like a fine pink Penzance, with long brilliant fruits." F. 298, 463, 784. 

This is very variable in cultivation, some being straggling in habit and of rather a washy colour, others being excellent in colour and most striking in fruit. It is quite hardy everywhere.
