Saffron is classified into Magnoliophyta division, class Liliopsida and order Asparagales. In some species, the sheath extends beyond the next node, so that consecutive leaf sheaths overlap, hiding the nodes.

Class Liliopsida

Retrieved 23 January The second largest to 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. This name is formed by replacing the termination -aceae in the name Liliaceae by the termination -opsida Art 16 of the ICBN.

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. With but a few exceptions, the green leaves arise at nodes alternately up the culm.

If the veins are conspicuous, the leaf is striate; if the veins are raised, the leaf is ribbed. 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 internal taxonomy in the Cronquist system is.

On the inner, upper surface of the leaf, between the sheath and the blade, is an outgrowth called a ligule. 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. Smaller units of the inflorescence are called spikelets and these are arranged on one or more branches in a wide variety of different liliopsifa to which the standard terminology for inflorescences can be applied, but using the spikelet instead of the individual flower.

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: Oh, the things you can do with bamboo! Roots may also develop from a node where the node comes into contact with the ground as in decumbent and prostrate stems. A stolon is a stem that creeps across the surface of the ground, and is really a basal branch of vlasse culm that will develop roots and shoots from some or all of its nodes.

The culm is a rounded or slightly flattened stem with one or more solid joints known as nodes. 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. 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. 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 longitudinal edges of the sheath may overlap, completely surrounding the culm, or the sheath may be tubular the margins connate.

Origin and dispersalEdinburgh: In summary the monocotyledons were named: The leaves are attached at the nodes and if the stem is not simple but branched, branches arise only at nodes.
