Notes and observations:
These plants were growing at the United States Plant Introduction Garden, Glenn Dale, MD; originally grown by the Office of Crop Physiology and Breeding Investigations (CPB), a section of the Division of Horticultural Crops and Diseases. Numbered in January 1935 for convenience and distribution. Upon brief observation, this accession was slightly drier with a thicker rind than Groff's description.
Description from George Weidman Groff's "Culture and Varieties of Siamese Pummelos as Related to Introductions into other Countries" (December, 1927):
"Kao Pan (which means "white flat") fruits are subglose, flattened, pistil-end depressed, and are without a neck. The rind is light to lemon yellow, smooth, and 1-2 centimeters thick. They have 12-15 segments, separating with difficulty. Flesh is light yellow. Each juice vesicle can be separated. They have a sweet, very mildly acid flavor, and there is slight to no bitterness."
Description from The Citrus Industry Vol. 1 (1967):
Fruit medium-large, subglobose to spherical; apex slightly depressed; seedy if open-pollinated, but otherwise not (Soost, 1964). Lemon-yellow (deeper than most) at maturity. Rind medium-thick; faintly pebbled with prominent oil glands; tightly adherent. Segments numerous (12-15); carpellary membranes thick and tough; axis medium-small and solid. Juice sacs large, fleshy, easily separable, and moderately juicy. Flavor sweet and mildly acid. Early in maturity.
Availability: Not commercially available in California.
