For instance, the parallel venation found in most monocots correlates with their elongated leaf shape and wide leaf base, while reticulate venation is seen in simple entire leaves, while digitate leaves typically have venation in which three or more primary veins diverge radially from a single point.
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.
Leaf venation is of the striate type, mainly arcuate-striate or longitudinally striate (parallel), less often palmate-striate or pinnate-striate with the leaf veins emerging at the leaf base and then running together at the apices. There is usually only one leaf per node because the leaf base encompasses more than half the circumference. [31]
The leaves are simple without lobes and can be up to 2 metres (6.6 ft) long and 3 to 11 centimetres (1.2 to 4.3 in) broad. They are without petioles and are broadly clasped at the base. The leaf venation is parallel running longitudinal. The blue/green to dark green leaves is rather stiff with a waxy texture.
They contain simple, bluish-green leaves with entire margins and are linear in shape. The blades tend to be 18–36 inches long. Like other grasses, the leaves also have parallel venation.
Leaves are typically simple, green, glabrous, and lanceolate, with margins that are entire. They appear in an opposite arrangement and are deciduous. They display fine parallel venation off of a central midrib. The upper surface of the leaves are usually a darker shade of green than the lower surfaces.
The stem of the largest of them may reach up to 7 cm (2.8 in) diameter, but most are much smaller. Leaves are simple, long linear to ovate, sessile; they are arranged in three spirals and venation is parallel. Leaf margins are often toothed or with small spines; the underside of the midrib may also be toothed.
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
