Quercus lamellosa (syn. Cyclobalanopsis lamellosa) is a species of oak (Quercus) native to the Himalaya and adjoining mountains from Tibet and Nepal east as far as Guangxi and northern Thailand, growing at altitudes of 1300–2500 m. [3] The Lepcha of Sikkim call it book koong. [4] It is placed in subgenus Cerris, section Cyclobalanopsis. [5]
Quercus lamellosa is a medium-sized to large evergreen tree growing to 40 m tall with a trunk up to 1.5 m diameter. The leaves are spirally arranged, ovate-elliptic, 16–45 cm long and 6–15 cm broad, with a sharply serrated margin. The flowers are catkins, the female flowers maturing into broad acorns 2–3 cm long and 3–4 cm broad, set in a deep cupule with concentric rings of woody scales. [3] [6]
Joseph Dalton Hooker commented,
Quercus lamellosa is occasionally cultivated as an ornamental tree in warm-temperate climates; in the British Isles, cultivation is only successful in the milder parts of Ireland and Cornwall. [8]
