On a Collection of Plants from Upper Burma and the Shan States.
Brigadier-General H. Collett, C.B., F.L.S., and W. Botting Hemsley, F.R.S., A.L.S.
Rosa gigantea, Collett; Crépin in Comptes-Rendus Soc. Bot. Belg. 1888, p. 150, et 1889, p. 11; Gard. Chron. 3rd series, vi. p. 13. (Plate IX.).—Shan hills plateau at 4000 to 5000 feet; abundant, though local.
Also in Muneypore, where Dr. Watt discovered it in 1882, at an altitude of 6000 feet.
A lofty climber with very thick stems, very conspicuous in the forests by reason of its large white flowers. A walking-stick made from a stem of this Rose has been deposited in the Kew Museum.
It is doubtful whether this is more than a very luxuriant state of R. indica, Linn., for some of the older specimens have flowers no more than 2 to 2 1/2 inches in diameter, and the flowers are sometimes corymbose.
