Rosa roxburghii, (the burr rose, chestnut rose, or chinquapin rose), is a species of flowering plant in the family Rosaceae, native to the eastern Himalayas, Tibet, and central and southern China.[1] In the wild it is found in thickets, mountain forests, on slopes, and alongside streams, typically 500 to 1,400 m (1,600 to 4,600 ft) above sea level.[2] A diffuse shrub capable of reaching 8 m (26 ft) but usually shorter, it is available from commercial suppliers.[3] In China, it is cultivated for its vitamin C-rich hips on 170,000 ha (420,000 acres), mostly in Guizhou.[4]

It was dedicated to William Roxburgh, a Scottish physician and botanist who was director of the Calcutta Botanical Garden.

Three forms have been recognized: Rosa roxburghii f. roxburghii, which has double or semi-double, reddish or pink flowers 5–6 cm (2.0–2.4 in) in diam.,Rosa roxburghii f. normalis Rehder & E. H. Wilson (in Sargent, Pl. Wilson. 2: 318. 1915), which has simple, pink flowers 4–6 cm (1.6–2.4 in) in diam. and also, Rosa roxburghii f. hirtula (Regel) (Rehder and Wilson), flowers single, pale pink or lilac-pink from Japan.
