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.
Fibrous roots grow fairly close to the surface of the ground. Leaves with parallel venation have fibrous roots. Forages have a fibrous root system, which helps erosion by unanchoring the plants to the top layer of the soil, and covering the entirety of the field, as it is a non-row crop. [2]
Within these the major veins function as the support and distribution network for leaves and are correlated with leaf shape. 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 ...
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 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 simple and palmately veined, 8–16 cm (3 + 1 ⁄ 4 – 6 + 1 ⁄ 4 in) long and 6–12 cm (2 + 1 ⁄ 4 – 4 + 3 ⁄ 4 in) broad, with deep angular notches between the five lobes. The 5–12 cm (2– 4 + 3 ⁄ 4 in) long, slender stalks of the leaves mean that even a light breeze can produce a striking effect as the downy silver ...
Vernation or leafing [1] is the formation of new leaves or fronds. In plant anatomy, it is the arrangement of leaves in a bud. In pine species, new leaves are short and encased in sheaths. Each leaf bundle consists of two to five needles. [citation needed] All the leaves on one section of branch
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]
