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.
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 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 ...
Gymnosperms are divided into 12 families of trees, shrubs and woody vines. [5] Sequoiadendron giganteum, the giant redwood, is the largest tree in the world, and Sequoia sempervirens, the coastal redwood, is the tallest. [6] Ginkgo trees tolerate urban pollutants well, and are often planted in and near cities. [7]
It reaches a height of 30–35 m (98–115 ft) and a diameter of 0.7 m (28 in). In the past, before extensive logging, they reportedly grew to 47 m (154 ft) with a diameter of 1.2 m (47 in). The tree is a cultural symbol of the Southern United States, being the official state tree of Alabama. [4]
The leaves are trifoliate, somewhat like a clover; the leaflets are typically 2–3 cm (0.8–1.2 in) long in L. anagyroides and 4–5 cm (1.5–2 in) long in L. alpinum. They have yellow pea- flowers in pendulous leafless racemes 10–40 cm (4–15.5 in) long in spring, which makes them very popular garden trees.
Members of the family Pinaceae are trees (rarely shrubs) growing from 2 to 100 metres (7 to 300 feet) tall, mostly evergreen (except the deciduous Larix and Pseudolarix), resinous, monoecious, with subopposite or whorled branches, and spirally arranged, linear (needle-like) leaves. [3] The embryos of Pinaceae have three to 24 cotyledons.
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.
