Birch 01

The pistillate segments are erect or pendulous, and solitary, terminal on the two-leaved lateral spur-like branchlets of the year. The pistillate scales are oblong-ovate, three-lobed, pale yellow-green often tinged with red, becoming brown at maturity

These scales bear two or three fertile flowers, each flower consisting of a naked o***y. The o***y is compressed, two-celled, and crowned with two slender styles; the ovule is solitary. Each scale bears a single small, winged nut that is oval, with two persistent stigmas at the apex.

The buds, forming early and full-grown by midsummer, are all lateral, without a terminal bud forming; the branch is prolonged by the upper lateral bud. The wood of all the species is close-grained with a satiny texture and capable of taking a fine polish; its fuel value is fair.

Birch species are generally small to medium-sized trees or shrubs, mostly of northern temperate and boreal climates.[4] The simple leaves are alternate, singly or doubly serrate, feather-veined, petiolate and stipulate.

Weathing and Roads are bad. Please do not go out if you do not have to! Stay Warm and Safe!

Trees up to 30 (45) m tall and shrubs (Betula humilis, Betula nana). The maximum age of most species of birch does not exceed 100-120 years, yellow birch - 150 years, individual trees reach 300 years. Most birches are frost-resistant, with the exception of Himalayan-Chinese, some Japanese and American black birches, which are more heat-demanding.
