[From The Ultimate Rose Book, by Stirling Macoboy, p. 72:] The French name 'Bengale' for the China Roses arises from the circumstance of the first ones to reach European gardens having travelled via the Botanic Gardens in Calcutta.

[From Roses on the Cote d'Azur, by Jean Murour, p. 96:] Bengal roses were raised from Rosa sempervirens or from R. chinensis.
