  2. Alstonia - Wikipedia

    en.wikipedia.org/wiki/Alstonia

    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.

    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 ...

  4. Monocotyledon - Wikipedia

    en.wikipedia.org/wiki/Monocotyledon

    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]

  5. Cymbopogon citratus - Wikipedia

    en.wikipedia.org/wiki/Cymbopogon_citratus

    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.

  6. Fibrous root system - Wikipedia

    en.wikipedia.org/wiki/Fibrous_root_system

    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]

  7. Pandanus utilis - Wikipedia

    en.wikipedia.org/wiki/Pandanus_utilis

    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.

  8. Curcuma angustifolia - Wikipedia

    en.wikipedia.org/wiki/Curcuma_angustifolia

    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.

  9. Chrysophyllum oliviforme - Wikipedia

    en.wikipedia.org/wiki/Chrysophyllum_oliviforme

    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.
