Broad leaves and reticulate leaf veins, features typical of dicots, are found in a wide variety of monocot families: for example, Trillium, Smilax (greenbriar), Pogonia (an orchid), and the Dioscoreales (yams). [35] Potamogeton and Paris quadrifolia (herb-paris) are examples of monocots with tetramerous flowers. Other plants exhibit a mixture ...
In the Aristida genus for example, one species (A. longifolia) is C3 but the approximately 300 other species are C4. As another example, the whole tribe of Andropogoneae, which includes maize, sorghum, sugar cane, "Job's tears", and bluestem grasses, is C4. [14] Around 46 percent of grass species are C4 plants.

Aside from cotyledon number, other broad differences have been noted between monocots and dicots, although these have proven to be differences primarily between monocots and eudicots. Many early-diverging dicot groups have monocot characteristics such as scattered vascular bundles, trimerous flowers, and non-tricolpate pollen. [5]
The earlier APG system (1998) adopted the same placement of the order, although it used the spelling "commelinoids". It did not include the Bromeliaceae and Mayaceae, but had the additional families Prioniaceae (now included in Thurniaceae), Sparganiaceae (now in Typhaceae), and Hydatellaceae (now transferred out of the monocots; recently discovered to be an 'early-diverging' lineage of ...
This page's list covers the monocotyledon plants found in Great Britain and Ireland. This clade includes grasses , lilies , orchids , irises and a wide variety of aquatic plants. Status key: * indicates an introduced species and e indicates an extinct species.
The commelinids are a group of 29 interrelated families of flowering plants, named for one of the four included orders, Commelinales. [a] This subgroup of the monocots accounts for most of the global agricultural output; the grass family alone contains the major cereal grains (including rice, wheat, and maize or corn), along with forage grasses, sugar cane, and bamboo.
Asparagales is roughly tied with Poales for the most diverse monocot order and includes Orchidaceae, the largest flowering plant family, with more than 26,000 species. [1] [12] Plants in Dioscoreales, such as yams, usually have inflorescences with glandular hairs. [13]
