Notes and observations

12/2/1987, EMN: Fruit examined and matched description in The Citrus Industry quite well.

11/7/2006, DK: Diamante is still the principal citron variety grown in Italy. It has a very thick rind, firm, fleshy albedo, and acid flesh.


Description from The Citrus Industry Vol. 1 (1967)

"Fruit large, long-oval to ellipsoid; basal cavity furrowed and surrounded by low collar; apex broadly nippled; and seedy.  Color lemon-yellow at maturity.  Rind very thick and fleshy; surface smooth and sometimes indistinctly lobed or ribbed.  Flesh crisp; lacking in juice, but acid, like lemon.

Tree small, open and spreading, medium-thorny with some large, stout spines; buds, flowers, and new growth purple-tinted.

Presumably of local though unknown origin, Diamante is the principal variety of Italy and according to Casella (1928) is considered to be the best.  It was introduced into the United States in 1898.  Italian and Sicilian are California introductions that are similar to Diamante."
