Later authors have modified the classes and have sometimes used leaf length as a simpler measure than leaf area if the leaf shape is approximately an ellipse. For example, L.J. Webb [3] used size classes: Microphyll: less than 2,025 square millimetres; Notophyll: 2,025–4,500 square millimetres; Mesophyll: greater than 4,500 square millimetres
whole leaf: Diamond-shaped rounded: rotundifolius: leaf tip or base: Circular, no distinct point semiterete: 3-D shape: Rounded on one side and flat on the other sagittate: sagittatus: whole leaf: Arrowhead-shaped with the lower lobes folded, or curled downward spatulate: spathulatus: whole leaf: Spoon-shaped; having a broad flat end which ...
Dendrology (Ancient Greek: δένδρον, dendron, "tree"; and Ancient Greek: -λογία, -logia, science of or study of) or xylology (Ancient Greek: ξύλον, ksulon, "wood") is the science and study of woody plants (trees, shrubs, and lianas), specifically, their taxonomic classifications. [1]
On every tree, the leaves vary in shape, ranging from narrow and elliptic to deeply divided. [6] The upper surface is glossy, contrasting with a pale undersurface. The adult leaf blades are 4–11 cm (1.6–4.3 in) long and 0.8–2 cm (0.3–0.8 in) wide with pointed (acuminate or apiculate) tips.
A leaf (pl.: leaves) is a principal appendage of the stem of a vascular plant, [1] usually borne laterally above ground and specialized for photosynthesis.Leaves are collectively called foliage, as in "autumn foliage", [2] [3] while the leaves, stem, flower, and fruit collectively form the shoot system. [4]
Leaf Base Shape: Semiamplexicaul – the leaf base wraps around the stem, but not completely. Leaf Blade Apex: Acuminate – narrowing to a point (a term used for other structures, too). Acute – with a sharp, rather abrupt ending-point. Acutifolius – with acute leaves. Attenuate – tapering gradually to a narrow end. Leaf Blade Margins:
Nature printed leaf, showing shape and venation. Ficus religiosa is a large dry season-deciduous or semi-evergreen tree up to 30 metres (98 ft) tall and with a trunk diameter of up to 3 metres (9.8 ft).
Even in nature, Acer palmatum displays considerable genetic variation, with seedlings from the same parent tree typically showing differences in such traits as leaf size, shape, and color. The overall form of the tree can vary from upright to weeping. [9] Three subspecies are recognised: [9] [10] Acer palmatum subsp. palmatum.
