There is an absence of terminal buds, and lateral buds often have a hook at the tip of the bud, which differs from other species in the family Betulaceae. [4] The leaves are alternate, ovate, 4–8 centimeters ( 1 + 1 ⁄ 2 – 3 + 1 ⁄ 4 in) long and 3–6 centimeters ( 1 + 1 ⁄ 4 – 2 + 1 ⁄ 4 in) broad, with a serrated margin and five to ...
The leaf buds are green. The bud scales are valvate . The flowers are white, produced in corymbs up to 13 cm (5 in) in diameter at the top of the stems; each corymb comprises a ring of outer sterile flowers 2–2.5 cm ( 3 ⁄ 4 –1 in) diameter with conspicuous petals, surrounding a center of small (5 mm, 0.20 in), fertile flowers; the flowers ...
The bud scales enlarge with the growing shoot and often become leaf-like. Like all viburnums, the leaves are arranged in opposite pairs on the twigs; they are oval, 5–10 cm (2–4 in) long and 2–5 cm ( 3 ⁄ 4 –2 in) broad, wedge-shaped, rounded or subcordate at base, with an acuminate apex and a finely serrated margin, and a winged petiole .
It is also occasionally confused for quaking aspen (Populus tremuloides), which has similar bark, but different leaves and buds. [4] Twigs are slender, wiry, hairless, dull gray or brown in color, and have a warty or rough texture. Buds are pointed, green-brown in color, shiny, and have a gummy coating. [4] Betula populifolia lacks terminal buds.
The pear-shaped nut ripens in September and October, has a sweet maple like smell, and is an important part of the diet of many wild animals. The wood is used for a variety of products, including fuel for home heating. Its leaves turn yellow in the Fall.
Shumard oak twigs terminate in a cluster of buds. The buds are lighter in color than the olive-green twigs. The young twig is highly reflective. [6] The leaves are arranged alternately and are broadly obovate with 5–9 lobes, each of which is terminated by bristle-tipped teeth. The leaves mature to between 10 and 21 cm (4 and 8 in) in length.
The winter buds are stout, ovate-acute, smooth, deep red, with two bud scales visible. The leaves are simple , alternately arranged, ovate to cordate , asymmetrical, unequal at the base (the side nearest the branch the largest), 10–15 cm (4–6 in) (can grow up to 25 cm or 10 in) long and broad, with a long, slender petiole, a coarsely ...
The fruit is a very bitter nut, 2–3 cm (3 ⁄ 4 – 1 + 1 ⁄ 4 in) long with a green four-valved cover which splits off at maturity in the fall, and a hard, bony shell. Another identifying characteristic is its bright sulfur-yellow winter bud.
