the Elder Pliny, The Natural History of Pliny, Volume 3…
“ The herb asarum,505 too, has the properties of nard, and, indeed, by some persons is known as wild nard. It has a leaf, 122however, more like that of the ivy, only that it is rounder and softer. The flower is purple, the root very similar to that of the Gallic nard, and the seed is like a grape. It is of a warm and vinous flavour, and blossoms twice a year, growing upon hill sides that are densely shaded. The best kind is that found in Pontus, and the next best that of Phrygia; that of Illyricum being only of third-rate quality. ”
