Biology:List of commelinid families

Short description: none

Rice seeds

For the other monocot families, see Biology:List of alismatid families.

The commelinids are a group of 29 interrelated families of flowering plants, named for one of the four included orders, Commelinales. 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. The palm, banana, ginger, pineapple and sedge families are also commelinids.

Traits common to most commelinids include partially fluorescent cell walls, starchy seeds and an extra layer of epidermal wax. Like other monocots, they usually have a single embryonic leaf (cotyledon) 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. These plants are found worldwide, even in mainland Antarctica; two species of grass are the only vascular plants found there.

Glossary

From the glossary of botanical terms:

• annual: a plant species that completes its life cycle within a single year or growing season
• basal: attached close to the base (of a plant or an evolutionary tree diagram)
• climber: a vine that leans on, twines around or clings to other plants for vertical support
• herbaceous: not woody; usually green and soft in texture
• perennial: not an annual or biennial
• woody: hard and lignified; not herbaceous

The APG IV system is the fourth in a series of plant taxonomies from the Angiosperm Phylogeny Group.

Arecaceae (palm family)	Areca was named for a Malabar plant.	180 genera, in the tropics, the subtropics, and some temperate regions	This family includes trees, shrubs, shrublets and climbers. Leaves are often sharp and prickly. The coco-de-mer has the heaviest seed of any plant, at up to 30 kilograms (66 lb), and Corypha umbraculifera has the largest inflorescence, with up to 10 million flowers. One 2000-year-old date palm seed has been germinated successfully.	Arecales	Areca catechu Areca catechu Areca catechu
Bromeliaceae (pineapple family)	Bromelia was named for Olof Bromelius (1639–1705), a Swedish doctor and botanist.	76 genera, widespread in the tropical and warm temperate Americas	These plants mostly grow on other plants or rocks. Leaves can be multihued, and are usually long and rigid. Spanish moss was formerly an important packing material in the southern United States. Puya chilensis is sometimes considered carnivorous, by virtue of its sharp-tipped leaves.	Poales	Bromelia pinguin Bromelia pinguin Bromelia pinguin
Cannaceae (canna-lily family)	Canna comes from a Greek plant name.	1 genus, in the tropics and subtropics of the Americas	These non-woody plants are tall, with many broad leaves.

Poaceae (grass family)	Poa comes from a Greek plant name.	793 genera, worldwide	These plants generally have adaptations that protect them from grazing animals, including a network of underground rhizomes and narrow leaves that grow from their base. This big family includes rice, wheat, maize or corn, most forage grasses, sugar cane, bamboo, and many other economically important plants. Bamboo stalks have been known to grow more than 2 meters (6 ft 7 in) per day. The global appearance of grasslands around 33 million years ago reduced atmospheric carbon dioxide over time and cooled the planet, largely thanks to C4 photosynthesis, which is efficient in hot climates.
