Roger Phillips: One of the most exciting roses we have in the [Eccleston] Square, Martyn Rix and I found in Sichuan Province many years ago; it is Rosa cymosa. Admittedly, it is a rather massive thing, but the flowers are probably the smallest of any rose; however they come in terminal bunches of about 50 or 60 so they make a fantastic showing. It is a bit borderline in terms of frost, so it is fine in London, but in our cottage in Wiltshire it survives, but fails to flower.

[Rosa collettii] was first described by Crépin, who classed it under the section Systylae and placed it next to Rosa microcarpa Lindl., with which he considered it had many points of resemblance, adding, however, that the specimens had suffered so much during their journey from the Calcutta Botanic Garden that he was unable to form a definite opinion upon the inflorescence, and pointing out that in Rosa microcarpa and in Rosa Collettii the columnar styles were much shorter than in other Systylae.

WILD CHINESE ROSES by Augustine Henry

Rosa microcarpa, Ldl., bears a considerable resemblance to Rosa Banksiae in the shape of the leaflets and of the stipules, and in the smallness of the flowers and fruit; but in it the styles are coherent. The most obvious distinction lies in the outer sepals of Rosa microcarpa, which have spinules on the back, and denticulate or spinuliform appendages on the margins. These spinules, &c., are totally wanting in Rosa Banksiae.

Rosa Colletti, Crépin, discovered in the Shan States of Burma, is very close to R. microcarpa, agreeing with it in styles, appendaged sepals, &c. It is apparently a tomentose geographical form of that species, and is interesting, because we find in certain plants (such as Albizzia Julibrissin), tomentose forms as we leave China and get into the warmer regions of Burma and India.
