Chart illustrating leaf morphology terms. 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 leaves appear relatively late in spring, and turn a clear pale yellow in autumn. The leaflets fold together in wet weather and at night , as some change of position at night is a habit of the entire leguminous family. Young trees are often spiny, especially on root suckers and branches near the ground; mature trees often lack spines.
The leaves are smooth, soft, linear in shape, 10–35 mm (0.4–1 in) long, and 1 mm (0.04 in) wide. They are also rich in oil with the glands prominent. Flowers occur in white or cream-colored masses of spikes 3–5 cm (1–2 in) long over a short period, mostly spring to early summer, and give the tree an appearance of looking fluffy.
In addition, these meanings are alluded to in older pictures, songs and writings. New symbols have also arisen: one of the most known in the United Kingdom is the red poppy as a symbol of remembrance of the fallen in war.
The leaves are simple, feather-veined, and typically linear-lanceolate. Usually they are serrate, rounded at base, acute or acuminate. The leaf petioles are short, the stipules often very conspicuous, resembling tiny, round leaves, and sometimes remaining for half the summer. On some species, however, they are small, inconspicuous, and caducous ...
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 corolla 4–6 centimetres ( 1 + 1 ⁄ 2 – 2 + 1 ⁄ 4 in) long resembling a foxglove flower.

Although live oaks retain their leaves nearly year-round, they are not true evergreens.Live oaks drop their leaves immediately before new leaves emerge in the spring. Occasionally, senescing leaves may turn yellow or contain brown spots in the winter, leading to the mistaken belief that the tree has oak wilt, whose symptoms typically occur in the sum
