Rosa hirtula, (commonly known as the 'sweet chestnut rose', 'chestnut rose', 'burr rose' or 'Chinquapin Rose'), is a member of the genus Rosa and classified in the subgenus Platyrhodon, it is native to China and Japan. It is a variable climbing wild rose species native to China and Japan. It has
(need short description later) It is found in mountain forests, on the banks of streams and on slopes between 500 and 1500 meters above sea level.
Another form is also mentioned in some places. Rosa roxburghii f. hirtula (Regel) Rehder and Wilson) with pale pink,[2] or lilac pink flowers, foliage pubescent beneath,[3] and leaflets are elliptic to oblong-elliptic and downy beneath.[2] Found prior to 1980.[3] It comes from Japan,[2] and is an RHS accepted name and ,[4]
This is more likely to be Rosa hirtula (Regel) Nakai,[5] a separate species which is an accepted name by The Plant List (of Kew Gardens),[6] but Germplasm Resources Information Network states Rosa hirtula (Regel) Nakai is as synonym of Rosa roxburghii Tratt. var. hirtula (Regel) Rehder & E. H. Wilson,[7] making it a variant. Rosa hirtula is similar in form to R. roxburghii Tratt., particularly to the single-flowered form, R. roxburghii f. normalis Rehder & E. H. Wils., and is distinguished by its tree-like habit, hairy rachis, and lanceolate to narrowly oblong leaflets with acuminate to acuminate-acute apex, serrulate margins, and hairy midveins on the lower surface.[5]

R. hirtula (Regel) Nakai
Distribution: Central Honshu R. hirtula is found in the mountains between the chestnut zone and the beech zone in the Fuji-Hakone areas of central Japan. This is a deciduous tree which grows pretty large for a rose. The trees the author saw were about five metres tall. As the name suggests, this rose has leaves which look like those of the Japanese Pepper tree, and gives pale pink flowers 5 to 6 cm across during the rainy season in early summer. Its hips, covered with sharp prickles, look just like small chestnut burrs. In Autumn, when the hips ripen, a rich sweet scent like strong vintage liqueur fills the air under the tree.[9]
hirtula means in latin 'weakly hairy'[10]
The causal fungus of a rust disease of Rosa hirtula, endemic to mountainous areas of Fuji-Hakone-Izu National Park, Japan, was thought to be a common species Phragmidium rosae-multiflorae. It was concluded to be a species distinct from P. rosae-multiflorae; and a new name, P. satoanum, was proposed for it.[11] it
