Citrus Medica Var. Limonum — Rough-Skin Lemon
This variety is very hardy, bears profusely, and requires much more water than does the orange. Being a strong, vigorous grower, it forms an excellent stock upon which to graft the citrus varieties. The flower is white, with a reddish tint outside. The fruit is generally oval, and contains many seeds. The pale yellow skin is rough and warty. The pulp is coarse-grained and very juicy. It comes true to seed.
