[citation needed] Leaves may be simple, with a single leaf blade, or compound, with several leaflets. Compound leaves may be pinnate with pinnae (leaflets) on both sides of a rachis (axis), or may be palmate with multiple leaflets arising from a single point. [1] Leaf structure is described by several terms that include:
The leathery, sessile, simple leaves are elliptical, ovate, linear or lanceolate and wedge-shaped at the base. The leaf blade is dorsiventral, medium-sized to large and disposed oppositely or in a whorl and with entire margin. The leaf venation is pinnate, with numerous veins ending in a marginal vein.
Chart illustrating 61 morphological terms describing leaf shape, margins and venation. While Diliff's mega-panoramas are a hard act to follow, I thought I would throw the metaphorical hat into the ring with this illustration. I created it with the desire to make a richly encyclopedic image/poster with lots of information about leaf morphology.
The leaves are alternate and are a shiny dark green on top and light brown on the bottom. They are simple leaf types with pinnate venation. The leaves are ovate and range in length from 3 to 11 cm (1.2 to 4.3 in). The breadth of the leaves ranges from 2 to 5 cm (0.79 to 1.97 in). The leaves are evergreen so they are present year round.
The leaves are deep green on the dorsal surface and light green on the ventral surface. The leaves are simple with pinnate venation. The leaves are leathery in texture and are toothed, with several to many small indentations along the margin of the leaf. [4]
The leaves are simple, 4–12 cm (2–5 in) and 3–8 cm broad, light green to glaucous, oval to cordate, with pinnate leaf venation, a mucronate apex, and an entire margin. They are arranged in opposite pairs or occasionally in whorls of three.
A leaf with laminar structure and pinnate venation. Two basic forms of leaves can be described considering the way the blade (lamina) is divided. A simple leaf has an undivided blade. However, the leaf may be dissected to form lobes, but the gaps between lobes do not reach to the main vein.
The primary leaf or leaves of a plant embryo which upon germination develops into the seed-leaf or the first set of leaves. craspedodromous Pinnate venation in which the secondary veins terminate at the margin s, often as teeth. crateriform In the shape of a saucer or shallow cup; hemispherical or more shallow. cremnophyte
