Cultivar or taxon

 

Citrus x aurantium L., pro sp. X Citrus trifoliata L. (sensu Mabberley 2004, Bayer et al. 2009); Citrus aurantium L. x Poncirus trifoliata (L.) Raf. (sec. Swingle and Reece 1967; sensu Tanaka sec. Cottin 2002)

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 short or long, wings medium, adjoining the blade. Leaflets one, margin crenate/crenulate, shade leaflet blades weakly conduplicate, sun leaflet blades weakly or strongly conduplicate. Scent of crushed leaflets spicy or peppery. Fruit as broad as long or longer than broad; rind yellow (7-10), yellow-orange (11), or orange (12); rind texture slightly rough (4-5); firmness leathery; navel absent; flesh orange; taste sour.

Notes

 

Swingle and Reece (1967) additionally noted that: "These hybrids greatly resemble citranges but seem to be even more vigorous and cold-resistant. The Brownell citradia (fig. 3-42) grows vigorously and fruits freely in northern Alabama at Tuscaloosa (Lat. 33° 12’ N.). It makes a good stock for the commonly cultivated citrus fruits."
