Shrub, tree, evergreen or not; monoecious. Leaf: simple, alternate, petioled; margin entire to lobed; stipules small, generally deciduous. Staminate inflorescence: catkin or stiff spike, many-flowered. Pistillate inflorescence: 1–few-flowered, generally above staminate inflorescence; involucre bracts many, generally overlapping, flat or cylindric. Staminate flower: calyx generally 4–6-lobed, minute; petals 0; stamens 4–12+. Pistillate flower: calyx generally 6-lobed, minute; petals 0; ovary inferior, style branches generally 3. Fruit: 1 nut subtended, partly enclosed by scaly, cup-like involucre or 1–3 nuts subtended, enclosed by spiny, bur-like involucre; mature years 1–2. Seed: generally 1.
7 genera, ± 900 species: generally northern hemisphere. [Li et al. 2004 Int J Plant Sci 165:311–324] Wood of Quercus critical for pre-20th century ship-building, charcoal for metallurgy; some now supply wood (Fagus, Quercus), cork (Quercus suber), food (Castanea, chestnut). Lithocarpus densiflorus moved to Notholithocarpus. —Scientific Editor: Thomas J. Rosatti.

Key to Fagaceae
Evergreen. Leaf: leathery, adaxially ± glabrous, green, abaxially golden, with densely spaced, minute, appressed scales, margin entire or ± wavy above middle; stipules generally deciduous. Staminate inflorescence: branched or not, stiff, clustered or not, ascending to erect. Pistillate inflorescence: clustered below staminate on same or separate stalk, 1–3-flowered. Staminate flower: sepals generally 6, minute; stamens generally 8–10+. Fruit: nuts 1–3, enclosed by spiny, bur-like involucre, ovoid to ± spheric, ± angled; mature year 2.Key to Chrysolepis
