Brittonia 56: 136-142. 2004-This article provides descriptions of Quercus hirtifolia, a new oak species endemic to eastern Mexico, and of depressa, a species poorly characterized in the literature. Due to the morphological resemblance of Q. hirtifolia to Q. hintoniorum, Q. hypoxantha, Q. eduardii, Q. laurina, and Q. depressa, a dichotomous key for their identification is provided.
