Citrus x aurantium L., pro sp. [Sweet Orange Group] (sensu Mabberley 1997, Bayer et al. 2009); Citrus sinensis (L.) Osbeck (sensu Swingle and Reece 1967; sensu Tanaka sec. Cottin 2002)
Hodgson (1967) noted that: "Trovita originated as a seedling from a fallen fruit, presumably of Washington navel, at the Citrus Research Center, Riverside, California, in 1916 and was released in 1935. It was selected in 1928 and described and named by H. B. Frost, the name being Esperanto for "found." In comparison with the parent variety, the fruit is smaller, juicier, and of milder flavor. The tree is more productive under desert conditions. Trovita has achieved little importance in California, but is said to be promising as an early juice variety in the Negev region of Israel and elsewhere."
Crown compact or dense, not weeping. First-year twig surface glabrous; second- or third-year twig surface striate; thorns absent or not persistent; prickles absent or not persistent. Petiole glabrous, length medium; wings narrow, adjoining the blade. Leaflets one, margin bluntly toothed, shade leaflet blades flat or weakly conduplicate, sun leaflet blades weakly conduplicate. Scent of crushed leaflets sweetly orange-like. Fruit as broad as long or longer than broad; rind yellow-orange (11), orange (12), or red-orange (13); rind texture slightly rough (4-5) or medium rough (6-7); firmness leathery; navel absent; flesh orange; taste acidic-sweet.
Hodgson (1967) provided the following additional notes on the cultivar: "This California variety is believed to be a Washington navel orange seedling. The fruit is early maturing, medium-small, few-seeded, juicy, and pleasantly flavored. The tree is vigorous, upright-growing, and productive, but with a tendency to alternate bearing."
