Views Read Edit View history. Smaller units of the inflorescence are called spikelets and these are arranged on one or loliopsida 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.
In the previous chapter we learned how to separate the two major flowering plant groups: 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.
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. Grasses [ edit ].
Leaves that are concentrated near the base where the internodes are very short are termed basal leaves ; leaves arising at nodes along an elongated culm are cauline leaves. This name is formed by replacing the termination -aceae in the name Liliaceae by the termination -opsida Art 16 of the ICBN.
The liliopsids are considered to form a monophyletic group evolved from an early dicot.
