Quercus chrysocalyx[1] is a tree species in the beech family Fagaceae; there are no known subspecies.[2][3] It is native to Cambodia, China (Yunnan), Laos, Thailand, and Vietnam.[4] It is placed in subgenus Cerris, section Cyclobalanopsis (the ring-cupped oaks).[5]
This oak tree grows up to 15 m tall, with large acorns – 25–30 mm, and has been recorded from Vietnam, where it may be called sồi quang.[6]
Quercus chrysocalyx was first described in 1921 by Paul Robert Hickel and Aimée Antoinette Camus.[1] The species epithet, chrysocalyx, is derived from the Greek chrysos ("gold") and kalyx, ("cup" or "calyx"), and describes the plant as having golden calyces.[7][8]
