A number of these differences are not unique to the monocots, and, while still useful, no one single feature will infallibly identify a plant as a monocot. [36] For example, trimerous flowers and monosulcate pollen are also found in magnoliids, [35] and exclusively adventitious roots are found in some of the Piperaceae. [35]

Lilioid monocots (lilioids, liliid monocots, petaloid monocots, petaloid lilioid monocots) is an informal name used for a grade (grouping of taxa with common characteristics) of five monocot orders (Petrosaviales, Dioscoreales, Pandanales, Liliales and Asparagales) in which the majority of species have flowers with relatively large, coloured tepals.
Plants in this family have evolved with a fair amount of morphological diversity despite genetic similarity. Common characteristics include large flowers with parts arranged in threes: with six colored or patterned petaloid tepals (undifferentiated petals and sepals) arranged in two whorls, six stamens and a superior ovary. The leaves are ...
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.

A mature flower. In this example, the perianth is separated into a calyx (sepals) and corolla (petals) The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone.

Flowers of Poaceae are characteristically arranged in spikelets, each having one or more florets. [8]: 12 The spikelets are further grouped into panicles or spikes. The part of the spikelet that ...
The commelinids are the only clade that the APG IV system has informally named within the monocots. The remaining monocots are a paraphyletic unit. Also known as the commelinid monocots it forms one of three groupings within the monocots, and the final branch; the other two groups are the alismatid monocots and the lilioid monocots.
