Origin

 

Hodgson (1967) noted that: "This new California variety is said to have originated as a limb sport in the Duarte area that was propagated by Paul Hackney of the Newhall Land and Water Company of Piru and came to prominence in their variety collection. Because of its attractive appearance and early maturity, Newhall is currently under trial in several districts of California."

Petiole glabrous, length medium; wings narrow, adjoining the blade. Leaflets one, margin 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 present; flesh orange; taste acidic-sweet.

Hodgson (1967) provided the following additional notes on the cultivar:
