Harward Valencia (sec. Cottin 2002)
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: "Harward Late originated at Tauranga and probably represents a clonal budline of nucellar seedling origin. The name Harward Valencia would therefore seem more appropriate."
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 entire (by misinterpretation) 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), or orange (12); rind texture slightly rough (4-5); firmness leathery; navel absent; flesh orange; taste acidic-sweet.
Hodgson (1967) provided the following additional notes on the cultivar: "This New Zealand variety is a seedling of Valencia with fruit that is indistinguishable from its parent. The tree is vigorous, large, and productive, and since its overall performance is thought to be superior it seems likely to replace Valencia in New Zealand."
