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
1 sp.: western North America. (Greek: false Lithocarpus) [Manos et al. 2008 Madroño 55:181–190] Molecular studies indicate closer relationship with Castanea, Castanopsis, Quercus than with Lithocarpus, from which it is now segregated.
Shrub, tree < 30(45) m, evergreen; trunk bark gray-brown. Leaf: petioles 10–25 mm; blade 3–14 cm, oblong to ± ovate, adaxially sparsely stellate-hairy, ± glabrous in age, abaxially fine-woolly, in age ± glabrous, base ± rounded, tip obtuse, margin entire to serrate; stipules early-deciduous. Staminate inflorescence: spike, stiff, spreading to erect, many-flowered, dense. Pistillate inflorescence: below staminate inflorescence on same or separate stalk, 1-flowered. Staminate flower: sepals 5–6, minute; stamens 10–12. Fruit: mature year 2; nut 1, 20–35 mm, ovoid to ± spheric, partly enclosed by cup-like involucre (cup); cup (1.5)2–3 cm diam, saucer-shaped, scales slender, ± tapered, reflexed to spreading.
