Leaves are mostly green in color due to the presence of a compound called chlorophyll which is essential for photosynthesis as it absorbs light energy from the Sun. A leaf with lighter-colored or white patches or edges is called a variegated leaf. Leaves can have many different shapes, sizes, textures and colors.
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]
A rain tree leaf is pinnate made of 6–16 leaflets, each leaflet is shaped like a diamond 2–4 centimetres (0.79–1.57 in) long and 1–2 centimetres (0.39–0.79 in) wide with a dull top surface and finely hairy beneath. The tree sheds its leaves for a while during dry periods. [6]
The tree growth habit is an evolutionary adaptation found in different groups of plants: by growing taller, trees are able to compete better for sunlight. [14] Trees tend to be tall and long-lived, [ 15 ] some reaching several thousand years old. [ 16 ]
An example species with shiny green leaves is A. alba, and an example species with matt waxy leaves is A. concolor. The tips of leaves are usually more or less notched (as in A. firma), but sometimes rounded or dull (as in A. concolor, A. magnifica) or sharp and prickly (as in A. bracteata, A. cephalonica, A. holophylla). The leaves of young ...
The leaves are variable, being 15–25 mm (5 ⁄ 8 –1 in) long and flat on young trees and shaded lower branches in older trees. The leaves are scalelike, 5–10 mm ( 1 ⁄ 4 – 3 ⁄ 8 in) long on shoots in full sun in the upper crown of older trees, with a full range of transition between the two extremes.
