Native of W. China; discovered by Prince Henri d’Orléans near Tatsien-lu in 1890, later found on Mt Omei by Wilson, who introduced it for Messrs Veitch, with whom it flowered in August 1908. It grows up to 6,000 ft elevation, and is perfectly hardy. It makes growths 10 or 12 ft long in a season. The stipules are rather remarkable.
