The Guernsey Lily belongs to this genus, and, though scarcely hardy, deserves mentioning here on account of its extensive culture. It received the name N. Sarniensis in error, being a naturalized plant in Gruernsey. It is a native of South Africa, and about the year 1680 a ship containing a quantity of its bulbs was wrecked in the Channel, and the bulbs washing ashore struck root and increased. But it is no longer found there in a wild state. It is a very beautiful plant with rose or scarlet umbellate flowers, appearing in Autumn before the leaves. Perianth 6-parted, tubeless.
