Poales
Poales is an order of flowering plants in the monocot clade. It includes grasses, sedges, bromeliads, cattails, and several other plant families.
Monocots: Monocots are flowering plants whose seeds typically contain one embryonic leaf. Poales is one of the largest and most diverse orders within this major flowering-plant lineage.
Grass flower: A grass flower is a small reproductive unit enclosed by specialized bracts called lemma and palea. Its reduced structure is a distinctive form of reproduction within Poales.
Rice: Rice is the cereal crop Oryza sativa, whose grains feed billions of people. It is a domesticated grass and one of Poales’ most consequential food crops.
APG IV system: The APG IV system is a 2016 classification of flowering plants based on phylogenetic evidence. It presents a modern family-level framework for recognizing Poales and its relatives.
Alismatales: Alismatales is an order of monocots that includes many aquatic and wetland flowering plants. Its wetland members can resemble Poales, but molecular evidence places them in a separate order.
Poaceae: Poaceae is the flowering-plant family of grasses, including cereals, bamboos, and lawn grasses. This family contains the order’s most familiar members and dominates many terrestrial habitats.
Spikelet: A spikelet is the basic cluster of florets and bracts that forms the grass inflorescence unit. This compact unit organizes grass flowers into the varied heads characteristic of Poaceae.
Maize: Maize is the cereal grass Zea mays, cultivated for food, feed, and industrial products. Its productivity and diverse uses make this Poales species globally important.
Commelinids: Commelinids are a major clade of monocots that includes palms, grasses, and several other orders. Poales belongs to this broader evolutionary group of monocot plants.
Juncaceae: Juncaceae is the rush family, a monocot family of grasslike plants in the order Poales. Rushes resemble grasses and sedges, yet belong to a separate family within the same order.
