The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). [1] The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or ...

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 emerge in mid-spring, but the flowers require day lengths of approximately 14 hours and 30 minutes to form, hence T. americana's range is limited to north of the 35th parallel. Time of flowering varies by several weeks depending on the latitude; early May in Canada and early June in the extreme southern extent.
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.

Its leaves are linear to narrowly elliptic, mostly 50–90 mm (2.0–3.5 in) long and 1–3 mm (0.039–0.118 in) wide, sometimes arranged singly, or in clusters of three.
