摘要

Quercus meavei is described and illustrated as a new species of section Lobatae in the Sierra Madre Oriental. It is compared to Q. albocincta, Q. acutifolia, Q. furfuracea, Q. grahamii, Q. skinneri, Q. uxoris and Q. xalapensis in the Acutifoliae group, which present a biennial pattern of maturation of fruits. Quercus meavei differs from these species in having ovoid to subspherical and glabrate acorns, leaves with a greater number of secondary veins [(12)14-19] impressed adaxially, a crispate leaf margin, long-ovoid buds with golden trichomes towards the apical scales and branchlets usually fulvo-tomentose.
