Abstract
A new and distinct cultivar Citrus limon (L.) Brum.f. is provided which displays a substantially different time for initial fruit harvest than the standard ‘Primofiori’ cultivar (non-patented in the United States). The attractive juicy fruit of the new cultivar commonly is initially ready for harvest by about the end of March. This follows greatly the typical October initial harvest time for the ‘Primofiori’ cultivar. The new cultivar is a diploid, and displays a relatively dense spreading growth habit. The supply of the fresh fruit market for consumption, use in beverages, and in cooking is facilitated at an atypical season of the year by the new cultivar.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.

A new and distinct cultivar of lemon tree having the following combination of characteristics: (a) displays diploidy, (b) forms attractive fruit which when compared to the ‘Primofiori’ cultivar displays a substantially later season of maturity, and (c) displays a relatively dense spreading growth habit; substantially as illustrated and described.
