Beech, gmelina, goomar teak, Kashmir tree, Malay beechwood, white teak, yamane), locally known as 'gamhar', is a fast-growing deciduous tree in the family Lamiaceae.
Beech is a fast-growing tree, which grows on different localities and prefers moist fertile valleys with 750–4500 mm rainfall. It does not thrive on ill-drained soils and remains stunted on dry, sandy or poor soils; drought also reduces it to a shrubby form. The tree attains moderate to large heights of up to 30 m, with a girth of 1.2 to 4 m. It has a chlorophyll layer just under the outer bark, which is pale yellow on the outside and white inside.
