Citrus medica var. limonum.
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 an:l very juicy. It comes true to seed.

It is now widely disseminated throughout the group, and in Kona, Hawaii, grows exceptionally well. This orange is said to produce true to seed.
