Miscellaneous -- Section Lobatae, sub-section Acutifoliae;
-- This species was formerly named Q. conspersa, but S. Valencia-
A. thinks that there were an error in the past, and that Q. conspersa is actually the species named formerly Q. acutifolia, so the name "conspersa" becomes a simple synonym; moreover, the species named formerly Q. acutifolia becomes Q. grahamii;
-- For S. Valencia- A. Q. correpta is a synonym of Q. sapotifolia ;
