Origin

 

Hodgson (1967) noted that: "This citrangequat is of the same parentage as Telfair and was first fruited at Thomasville, Georgia. The cross was made in 1909, and the variety was named and described in 1923 (Swingle and Robinson 1923, p. 230)."

Petiole glabrous, length medium; wings absent or, if present, wide, adjoining the blade or tucking beneath blade. Leaflets one, margin crenate/crenulate or bluntly toothed, shade leaflet blades 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 (7-10), yellow-orange (11), orange (12), or red-orange (13); rind texture slightly rough (4-5); firmness leathery; navel absent; flesh orange; taste sour.
