Notes and observations

Primofiori is listed as a synonym for Mesero lemon which is therein described.

12/2/1987, EMN: Fruit examined- a market type lemon- large fruit this season.

10/1988, EMN: Re initial note on reverse: Primofiore is not the same as Primofiori (Mesero), so sayeth the Citrus Industry on pp 565. Which do we have?

Description from The Citrus Industry Vol. 1 (1967)

"Fruit spherical to oval; nipple comparatively small and sharp-pointed; moderately seedy.  Paler in color than Berna and rind smoother and thinner.  Also higher in juice and acid content.  Crop comes mainly in winter.

Tree exceptionally vigorous, attaining large size, very thorny, and highly productive.  Foliage density and leaf size greater than Berna.

This variety, of unknown Spanish origin, is said to be preferred by processors, but is much less extensively grown than Berna.  It should not be confused with the Primofiore of Italy which refers to fruit produced from the first or spring bloom."


Not commercially available in California.
