-- A. Camus n 274;
-- related to
Q.stellata, of which it differs in having slender twigs, smaller and thinner leaves, smaller and red brown buds;
-- one should not confuse Q.ashei Sterret with Q.x ashei Trel. that is a hybrid between
Q.laevis and Q.incana (and therefore is not a "white oak", as it is in Section Lobatae).
