One of the type of R macrophylla,, and therefore notable for its hips, bright red and large, the old sepals playing their trick of elongation. the flowers are pink. The stems grow stout and strong up to about head high, and then reach out from the plant in a great arch. R davidii comes from the area where China joins the east of Tibet.

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.
