| Subspecies and varieties |
-- The specimens from China have been isolated as true species by Hickel & A. Camus under name Q. chrysocalyx (opinion shared with Govaerts & Frodin), but are actually conspecific with Q.blakei; -- The plants from Hainan have small leaves, and have
been described under "var. parvifolia Merrill 1942",
but they are, for Menitsky (1974) probably a geographical form; |
