Cyperaceae; Gramineae; Bromeliaceae; and Zingiberaceae. The longitudinal edges of the sheath may overlap, completely surrounding the culm, or the sheath may be tubular the margins connate. Takhtajan, Armen Leonovich This page was last edited on 13 Februaryat The grasses have reduced floral structures compared with most angiosperms for the reason that grasses are almost exclusively pollinated by wind.

class Liliopsida

The liliopsids are considered to form a monophyletic group evolved from an early dicot. Thus, grasses with extensive rhizome development will form a turf rather than distinct tufts or bunches.

The culm is the main aerial shoot to which leaves and flower head are attached. 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.

If the veins are conspicuous, the leaf is striate; if the veins are raised, the leaf is ribbed.

Although in principle it is true that circumscription of this class will vary with the taxonomic system being used, in practice this name is very strongly linked to the Cronquist systemand the allied Takhtajan system. The grasses also have a fairly specific body plan that is immediately recognizable and very successful for colonizing seasonally dry landscapes, yet modifiable to suit llliopsida wide range of ecological conditions.

Rhizomes enable the grass plant to spread horizontally as new culms develop vertically from the joints. Liliaceae Monocots Plant classes.

The upper end of the sheath, known as the sheath mouth is the collar on the lower outer surface that may be produced into short appendages called auricles. Smaller units of the lillopsida are called spikelets and these are arranged on one or more branches in a wide variety of different ways to which the standard terminology for inflorescences can be applied, but vlasse the spikelet instead of the individual flower.

Kubitzki, Klaused. Therefore, these plants have had no cause to evolve floral structures that are attractive to insect or other animal pollinators. Views Read Edit View history.
