Lima Acidless Sweet Orange

Source: Received as budwood from Col. J. de Tieve e Argollo, Agua Comprida, Bahia- thru USDA, 1916.

Parentage/origins: Parents unknown.

Description: “Fruit medium-small, spherical to subglobose; seeds comparatively few. Rind medium-thick; surface slightly rugose; color light orange. Flesh color light yellow; tender and juicy; flavor insipid because of lack of acid. Very early in maturity. Lima is said to be the most important of the three non-acid orange varieties grown in Brazil, where this fruit is so highly appreciated that it currently constitutes about 10 per cent of the plantings. It is accorded particular dietary values for adults and is reported to be especially popular with children.”
