The bark of Pinus thunbergii is made up of countless shiny layers. Bark is the outermost layer of stems and roots of woody plants. Plants with bark include trees, woody vines, and shrubs. Bark refers to all the tissues outside the vascular cambium and is a nontechnical term. [1] It overlays the wood and consists of the inner bark and the outer ...
The bark of young trees is smooth, glossy and greenish-brown while in older trees it is dark grey and fissured. The branches are smooth and somewhat sticky, being scattered with resinous warts. The buds are purplish-brown and have short stalks. Both male and female catkins form in the autumn and remain dormant during the winter. [5]
Its bark is an excellent fire starter; it ignites at high temperatures even when wet. The bark has an energy density of 5,740 cal/g (24,000 J/g) and 3,209 cal/cm 3 (220,000 J/cu in), the highest per unit weight of 24 species tested. [11] Birch bark is used in a number of crafts by various Native American tribes (e.g. Ojibwe). [22]
Open-grown trees have egg-shaped crowns. [2] Heavy release sometimes results in epicormic branching. On mature trees, the bark peels away from the trunk in long, sometimes broad, strips. This gives the trees a “shaggy” appearance that is easily confused with that of the Shagbark hickory (Carya ovata). That close similarity is the reason ...
Trees can be girdled by climbing, twining, and ground-creeping (rampant) vines. There are several invasive species that harm trees in this way and cause significant damage to forest canopy and the health of ecosystems dependent on it. Oriental Bittersweet, Oriental Wisteria, and English Ivy all can damage and kill trees by girdling. [citation ...

The dark horizontal lines on silver birch bark are the lenticels. [1]A lenticel is a porous tissue consisting of cells with large intercellular spaces in the periderm of the secondarily thickened organs and the bark of woody stems and roots of gymnosperms and dicotyledonous flowering plants. [2]
Fagus grandifolia is a large deciduous tree [6] growing to 16–35 metres (52–115 feet) tall, [7] with smooth, silver-gray bark.The leaves are dark green, simple and sparsely-toothed with small teeth that terminate each vein, 6–12 centimetres (2 + 1 ⁄ 4 – 4 + 3 ⁄ 4 inches) long (rarely 15 cm or 6 in), with a short petiole.
