'''''Rosa gigantea''''' is a species of [[rose]] native to northeast [[India]], northern [[Myanmar]] and southwest [[China]] ([[Yunnan]]) in the foothills of the [[Himalaya]] at 1000-1500 m altitude. As its name suggests, it is the largest species of rose, climbing 20 m or more into the crowns of other [[tree]]s by means of its stout, hooked thorns, and with a trunk up to 50 cm diameter. The [[leaf|leaves]] are semi-evergreen, 15-25 cm long, pinnate, with usually 7 leaflets, each leaflet 4-8 cm long. The [[flower]]s are white, creamy or yellow, the largest of any wild rose, 10-14 cm diameter. The [[rose hip|hips]] are yellow or orange, 2.5-3.5 cm diameter, hard, and often lasting through the winter into the following spring, often still present at the same time as the next years' flowers.
Another rose, described from [[Manipur]] in [[1888]] as ''R. macrocarpa'' and ''R. xanthocarpa'' by [[Sir George Watt]], an authority on [[India]]n [[rose]]s, is now generally considered to be the same species as ''R. gigantea''. The distinct characteristics claimed for ''R. macrocarpa'' (deeper yellow flowers, larger foliage with 4 to 7 leaflets and large yellow fruits) are not consistent.
