Cultivar or taxon

Citrus x aurantium L., pro sp. X (Citrus x aurantium L., pro sp. [Sweet Orange Group] X Citrus trifoliata L.) (sensu Mabberley 2004, Bayer et al. 2009); Citrus sinensis (L.) Osbeck X (Citrus sinensis (L.) Osbeck x Poncirus trifoliata (L.) Raf.) (sensu Swingle and Reece 1967; sensu Tanaka sec. Cottin 2002; sec. NPGS/GRIN 2010)

Description

Crown compact or dense, not weeping. First-year twig surface glabrous; second- or third-year twig surface striate; thorns straight; prickles absent or not persistent. Petiole glabrous, length long, wings narrow, adjoining the blade. Leaflets one or three, margin bluntly toothed, rachis wings absent, shade leaflet blades weakly conduplicate, sun leaflet blades weakly or strongly conduplicate. Scent of crushed leaflets sweetly orange-like. Fruit broader than long, or as broad as long, or longer than broad; rind light green with some break to yellow (5), green-yellow (6), yellow (7-10), yellow-orange (11), orange (12), or red-orange (13); rind texture slightly rough (4-5), medium rough (6-7), or rough (8); firmness leathery; navel absent; flesh orange or yellow; taste sour.

Swingle and Reece (1967) provided the following additional notes on the group: "These hybrids are often very like the sweet orange in leaf characters; the fruits have not as yet been studied. The orange-like seedlings resemble also the orange-like second-generation seedlings of the fertile citrange varieties. Some of the citrangors show trifoliolate leaves and look much like citranges (see Swingle, 1910, p. 36, pls. 7, 8)."
