In temt.erate or colder zones where a See also:season favourable to vegetation is succeeded by an unfavourable or See also:winter season, leaves of evergreens must be protected from the See also:frost and See also:cold drying winds, and are therefore tougher or more leathery in texture than those of deciduous trees, and frequently, as in pines, firs and other conifers, are See also:needle-like, thus exposing a much smaller See also:surface to the drying See also:action of cold winds.
