Hodgson (1967) noted that: "This variety originated as a chance seedling in Nagasaki Prefecture of Japan, was named and introduced about 1910, and is currently second in importance there."
The Chiefland Budwood Facility (2010) provided the following notes on the cultivar (clone DPI-833-65): " This Hirado Buntan selection originated from a seedling tree."
Crown compact or dense, not weeping. First-year twig surface pubescent; second- or third-year twig surface striate; thorns absent or not persistent; prickles absent or not persistent. Petiole pubescent, length medium; wings medium or wide, adjoining the blade or tucking beneath blade. Leaflets one, margin entire, shade leaflet blades weakly conduplicate, sun leaflet blades weakly conduplicate. Leaflets not scented when crushed. Fruit broader than long, as broad as long, or longer than broad; rind green-yellow (6), yellow (7-10), or yellow-orange (11); rind texture smooth (1-3) or slightly rough (4-5); firmness leathery; navel absent; flesh red/purplish-tinged or yellow; taste grapefruit-like.
Hodgson (1967) provided the following additional notes on the cultivar:
"Fruit large, oblate, slightly depressed at both ends; seedy. Color bright yellow when mature. Rind medium thick; surface smooth and glossy; tightly adherent. Segments numerous and carpellary membranes thin but tough. Flesh light greenish-yellow; tender and moderately juicy; flavor a pleasant blend of sugar and acid with trace of bitterness. Medium-early in maturity but stores well.
Tree vigorous, medium-large; leaves large, thick, and broadly winged. More cold-resistant than most pummelos."
The Chiefland Budwood Facility (2010) provided the following additional notes on the cultivar (clone DPI-833-65): "Fruit is pink fleshed, of very large size, round to oblate shape. Good sweet flavor and juicy. Season is November- March. Tree is alternate bearing."
