Description from The Citrus Industry Vol. 1 (1967)
"Fruit large, broadly pyriform with distinct neck; apex even or slightly depressed; seedy if open-pollinated but otherwise not (Soost, 1964). Lemon-yellow at maturity. Rind medium-thick; surface smooth, glossy; less tightly adherent than Kao Pan. Segments numerous and easily separable; carpellary membranes moderately thick and tough; axis small and solid. Vesicles large, easily separable, and firm but juicy. Flavor good (more acid than Kao Pan). Medium-late in maturity and holds well on tree with retention of quality.
Tree similar to Kao Pan, but somewhat more vigorous and upright.
Groff (1927) reports that Kao Phuang is recognized as one of the two best varieties in Thailand, some persons preferring it to the famous Kao Pan. In California, its flavor is clearly superior. In the collections at the University of California Citrus Research Center, Riverside, one of several clones received under the name Siamese is indistinguishable from Kao Phuang, and is probably identical."
Not commercially available in California.
