From Wikipedia, the free encyclopedia. Arecidaesubclass Arecidae – one of four subclasses or superorder of Monocotyledones; comprises about species in 5 families of trees and shrubs and terrestrial herbs and a few free-floating aquatics including: This page was last edited on 13 Februaryat The leaves are attached at the nodes and if the stem is not simple but branched, branches arise only at nodes.

If the veins are conspicuous, the leaf is striate; if the veins are raised, the leaf is ribbed. The grasses have reduced floral structures compared with most angiosperms for the reason that grasses are almost exclusively pollinated by wind. Monocotyledoneae in the de Candolle system and the Engler system.
Palmae; Araceae; Pandanaceae and Lemnaceae Commelinidaesubclass Commelinidae – one of four subclasses or superorders of Monocotyledones; comprises about 19, species in 25 families of mostly terrestrial herbs especially of moist places including: Grasses display two types of leaves: Grasses that grow in shady places may have lanceolate or even ovate leaf blades.
The second largest liliopsidq Orchidaceae and one of the most successful of families of monocotyledons is the grass family, classified as the Family Poaceae or Gramineae and comprising nearly 10, species distributed more widely than any other angiosperm family.
Policies and guidelines Contact us. On the inner, upper surface of the leaf, between the sheath and the blade, is an outgrowth called a ligule. Quantitave studies of inter-relationships amongst the Liliatae. 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.
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. Liliaceae Monocots Plant classes. 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 a wide range of ecological conditions. Commelinidaesubclass Commelinidae – one of four subclasses or superorders of Monocotyledones; comprises about 19, species in 25 families of mostly terrestrial herbs especially of moist places including: The Takhtajan system used this internal taxonomy:.
AlismalesNaiadalesorder Alismalesorder Naiadales – an order of aquatic monocotyledonous herbaceous plants. The sheath of the leaf surrounds and protects the shoot.
Rhizomes enable the grass plant to spread horizontally as new culms develop vertically from the joints. AngiospermaeAnthophytaclass Angiospermaedivision Anthophytadivision MagnoliophytaMagnoliophyta – comprising flowering plants that produce seeds enclosed in an ovary; in some systems considered a class Angiospermae and in others a division Magnoliophyta or Anthophyta.
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. Therefore, in practice the name Liliopsida will almost surely refer to the usage as in the Cronquist system. Liliidaesubclass Liliidae – one of four subclasses or superorders of Monocotyledones; comprises 17 lilkopsida including: CS1 Russian-language sources ru.
Retrieved from ” https: Although there is variation in leaf blade shape, most grasses have linear-shaped leaves that are many times longer than wide, with margins that are parallel then taper to a point at the apex.
Class Liliopsida – definition of class Liliopsida by The Free Dictionary
Takhtajan, Armen Luliopsida Therefore, these plants have had no cause to evolve floral structures that are attractive to insect or other animal pollinators. These vegetative leaves typically surround the culm as a sheaththen diverge outward at the “collar” as a long narrow blade with longitudinal parallel venation.
C Jeffrey, as Flowering plants: In other projects Wikimedia Commons. Earlier systems referred to this group by the name Monocotyledones, with Monocotyledoneae an earlier spelling these names may be used in any rank. 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 the standard terminology for inflorescences can be applied, but using the spikelet instead of the individual flower.
This may be a flap of membranous tissue or simply a fringe of hairs, an inconspicuous rim, or even absent all together, marked only by dark tissue. Palmae; Araceae; Pandanaceae and Lemnaceae. 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 13 August In the previous chapter we learned how to separate the two major flowering plant groups: Switch to new thesaurus.
Grasses [ edit ]. The culm is the main aerial shoot to which leaves and flower head are attached.
