Liliopsida – Wikipedia

A rhizome is a modified stem that grows underground. Policies and guidelines Contact us. Magnoliophyta II The Class Liliopsida constitutes the monocotyledonous angiosperms and includes some of the largest plant families such as the orchids with some 20, species and the grasses with perhaps 15, species.

These vegetative leaves typically surround the culm as a sheaththen diverge outward at the “collar” as a long narrow blade with longitudinal parallel venation.

Liliopsida

In summary the monocotyledons were named: In the previous chapter we learned how to separate the two major flowering plant groups: Systems such as the Dahlgren and Thorne systems more recent than the Takhtajan and Cronquist systems refer to this group by the name Liliidae a name in the rank of subclass. The internal taxonomy in the Cronquist system is.

The portion of the stem between the nodes is called the internodeand is usually hollow in temperate zone grasses and solid in tropical grasses Rotar, Retrieved from ” https: Flowers of grasses are borne in an inflorescence or flower head which terminates the culm and other branches of the stem.

On the inner, upper surface of the leaf, between the sheath and the blade, is an outgrowth called a ligule.

Grasses have fibrous roots and three kinds of stems: The longitudinal edges of the sheath may overlap, completely surrounding the culm, or the sheath may be tubular the margins connate. Smaller units of the inflorescence are called spikelets and these are arranged on one or more branches in a wide variety of different ways to which liliopeida standard terminology for inflorescences can be applied, but using the spikelet instead of the individual flower. Retrieved 13 August If the veins are conspicuous, the leaf is striate; if the veins are raised, the leaf is ribbed.

In some species, the lillopsida extends beyond the next node, so that consecutive leaf sheaths overlap, hiding the nodes. Grasses display two types of leaves: A stolon is a stem that creeps across the surface of the ground, and is really a basal branch of the culm that will develop roots and shoots from some or all of its nodes.

Liliaceae Monocots Plant classes. By using this site, you agree to the Terms of Use and Privacy Policy. This page was last edited on 13 Februaryat Features that are generally common to monocots include vascular bundles that are irregularly distributed in cross-section of the stemleaves with parallel venation, and flower parts in multiples of three.

The Takhtajan system used this internal taxonomy:. The leaves are attached at the nodes and if the stem is not simple but branched, branches arise only at nodes. Kubitzki, Klaused.

Therefore, these plants have had no cause to evolve floral structures that are attractive to insect or other animal pollinators. Roots may also develop from a node where the node comes into contact with the ground as in decumbent lilliopsida prostrate stems. From Wikibooks, open books for an open world.

The sheath of the leaf surrounds and protects the shoot. Evolution and classification of higher categories. Retrieved 23 January Liliatae [1] is a botanical name for the class containing the family Liliaceae or Lily Family. The grasses have reduced floral structures compared with most angiosperms for the reason that grasses are almost exclusively pollinated by wind.
