The leaves are 8–20 centimetres (3 + 1 ⁄ 4 – 7 + 3 ⁄ 4 inches) long and 3–6 cm (1 + 1 ⁄ 4 – 2 + 1 ⁄ 4 in) wide, with 14–20 small saw-tooth-like triangular lobes on each side, with teeth of very regular shape. [3] The flowers are wind-pollinated catkins.
Quercus agrifolia, the California live oak, [3] or coast live oak, is an evergreen [4] live oak native to the California Floristic Province.Live oaks are so-called because they keep living leaves on the tree all year, adding young leaves and shedding dead leaves simultaneously rather than dropping dead leaves en masse in the autumn like a true deciduous tree.

The leaves are rough on top and glabrous or nearly glabrous on the underside. They are green to dark green in spring and throughout the summer, changing to yellows, oranges and reds in autumn. The petioles are 2–5 mm (1 ⁄ 16 – 3 ⁄ 16 in) long. [6] Zelkova serrata is monoecious. It develops flowers in spring with the leaves.
Quercus laurifolia is a tree growing to 20–24 meters (65–80 feet) (rarely to 40 m or 130 ft) tall, with a large, circular crown. The leaves are broad lanceolate, 2.5–12.7 centimeters (1–5 inches) long and 1.3–4.4 cm (1 ⁄ 2 – 1 + 3 ⁄ 4 in) broad, and unlobed (very rarely three-lobed) with an entire margin and a bristle tip; they typically fall just as the new leaves start to ...
The leaves turn golden yellow to red [4] in autumn (less reliably in warmer areas). In Texas, specimens do not color well if they have a heavy seed year. [5] The flowers appear with the leaves in mid spring; they are produced in corymbs of 5–15 together, each flower yellow-green, about 4–5 millimetres (3 ⁄ 16 – 3 ⁄ 16 in
Leaf of Populus grandidentata or "big-tooth aspen". Bigtooth aspens are dioecious, medium-sized deciduous trees with straight trunks and gently ascending branches.Heights at maturity are around 60–80 feet (18–24 m) with diameters of 8–10 inches (20–25 cm).
The leaves can be mistaken for those of the catalpa. The very fragrant flowers, large and violet-blue in colour [14] are produced before the leaves in early spring, on panicles 10–30 centimetres (4–12 in) long, with a tubular purple corolla4–6 centimetres (1 + 1 ⁄ 2 – 2 + 1 ⁄ 4 in) long resembling a foxglove flower.
Individual trees can live for over 300 years. [ 4 ] The leaves are thick with a waxy texture, elliptical, 7 to 15 cm ( 2 + 3 ⁄ 4 to 6 in) long and 4 to 8 cm ( 1 + 1 ⁄ 2 to 3 + 1 ⁄ 4 in) broad, arranged spirally; they are glossy dark green above and a lighter, more grayish green beneath, with an entire margin.
