Juncaceae
Juncaceae is a family of flowering plants known as rushes, typically with grasslike leaves and stems and often growing in wet habitats.
Poales: An order of monocot flowering plants that includes grasses, sedges, rushes, and several related families. Juncaceae belongs to this order alongside its frequent lookalikes, the grasses and sedges.
Inflorescence: The arrangement of flowers on a plant axis or group of axes. Rush flowers are commonly grouped in open or compact inflorescences, often appearing lateral because of a bract.
Wetland: An ecosystem where water saturates or covers the soil for all or part of the year. Many Juncaceae species are characteristic plants of marshes, fens, and other wetlands.
Plant systematics: The study of plant diversity and the evolutionary relationships used to classify plants. Systematic research establishes the family's boundaries and relationships among its genera.
Monocotyledon: A flowering plant whose seed embryo typically has one cotyledon, or embryonic leaf. Rushes are monocots, sharing characteristic floral and developmental traits with grasses and sedges.
Tepal: A floral segment that is not clearly differentiated into a sepal or petal. Rush flowers typically have six similar tepals rather than distinct petals and sepals.
Phytoremediation: The use of plants and their associated microbes to remove, contain, or transform environmental pollutants. Some rushes are used in constructed wetlands that treat contaminated water.
Angiosperm: A flowering plant whose seeds develop enclosed within an ovary that usually becomes a fruit. Juncaceae belongs to the flowering plants, whose defining reproductive structures are flowers and enclosed seeds.
Juncus: A large genus of rushes with solid stems and small flowers, widespread in moist habitats. It is the largest genus in the family and includes many familiar rushes.
Capsule (fruit): A dry fruit that splits open at maturity to release its seeds. Many Juncaceae produce capsules containing several small seeds.
