Many monocots are herbaceous and do not have the ability to increase the width of a stem (secondary growth) via the same kind of vascular cambium found in non-monocot woody plants. [34] However, some monocots do have secondary growth; because this does not arise from a single vascular cambium producing xylem inwards and phloem outwards, it is ...
The alismatid monocots are a group of 15 interrelated families of flowering plants, named for their largest order, Alismatales. [a] Like other monocots, they usually have a single embryonic leaf in their seeds, scattered vascular systems, leaves with parallel veins, flowers with parts in threes or multiples of three, and roots that can develop in more than one place along the stems.

The basal eudicots are a group of 13 related families of flowering plants in four orders: Buxales, Proteales, Ranunculales and Trochodendrales. [1] [a] Like the core eudicots (the rest of the eudicots), they have pollen grains with three colpi (grooves) or other derived structures, [4] and usually have flowers with four or five petals (sometimes multiples of four or five, sometimes reduced or ...
The flowers may be arranged (inflorescence) along the stem, developing from the base, or as a single flower at the tip of the stem, or as a cluster of flowers. They contain both male (androecium) and female (gynoecium) characteristics and are symmetric radially, but sometimes as a mirror image.
Zingiberales are one of an ecologically and morphologically diverse and species-rich order of monocots, with one of the most distinct floral morphology. [6] [7] [8] They are large rhizomatous herbaceous plants but lacking an aerial stem, except when flowering.
Juncaceae is a family of flowering plants, commonly known as the rush family. It consists of 8 genera and about 464 known species [2] of slow-growing, rhizomatous, herbaceous monocotyledonous plants that may superficially resemble grasses and sedges. They often grow on infertile soils in a wide range of moisture conditions.
The flowers are usually hermaphroditic—maize being an important exception—and mainly anemophilous or wind-pollinated, although insects occasionally play a role. [10] The perianth is reduced to two scales, called lodicules , [ 8 ] : 11 that expand and contract to spread the lemma and palea; these are generally interpreted to be modified sepals.
