Juncaceae family of flowering plants commonly known as rushes

Juncaceae is a family of flowering plants, commonly known as the rush family. It consists of 8 genera and about 464 known species of slow-growing, rhizomatous, herbaceous monocotyledonous plants that may superficially resemble grasses and sedges. They often grow on infertile soils in a wide range of moisture conditions. The best-known and largest genus is Juncus. Most of the Juncus species grow exclusively in wetland habitats. A few rushes, such as Juncus bufonius are annuals, but most are perennials.

<i>Juncus</i> genus of flowering plants in the rush family Juncaceae

Juncus is a genus of monocotyledonous flowering plants, commonly known as rushes. It is the largest genus in the family Juncaceae, containing around 300 species.

<i>Juncus effusus</i> Species of flowering plant in the rush family Juncaceae

Juncus effusus, with the common names common rush or soft rush, is a perennial herbaceous flowering plant species in the rush family Juncaceae. In North America, the common name soft rush also refers to Juncus interior.

<i>Juncus tenuis</i> Species of grass

Juncus tenuis, the slender rush, is a clump-forming, round-stemmed perennial in the Juncaceae. Slender rush grows to be between 15 and 60 cm tall.

<i>Juncus acutus</i> Species of grass

Juncus acutus, the spiny rush, sharp rush or sharp-pointed rush, is a flowering plant in the monocot family Juncaceae.

<i>Juncus articulatus</i> Species of grass

Juncus articulatus is a flowering plant species in the rush family Juncaceae. It is known by the common name jointleaf rush or jointed rush, which can also refer to J. kraussii from Australia. It is native to Eurasia, Canada, Greenland, and much of the United States. It grows in moist areas, such as wet sand, and thrives in calcareous soils. J. articulatus was found to be more sensitive to drought and salt stress than its congeners J. acutus and J. maritimus. It is a perennial herb producing mainly erect stems from a short rhizome. The stem may root at nodes, and it generally has one or more flattened hollow cylindrical leaves up to 10 centimeters long. Transverse internal partitions or joints may be seen or felt in the leaf of the plant.

Graminoid

In botany and ecology, graminoid refers to a herbaceous plant with a grass-like morphology, i.e. elongated culms with long, blade-like leaves. They are contrasted to forbs, herbaceous plants without grass-like features.

<i>Juncus dichotomus</i> Species of grass

Juncus dichotomus is a monocot which belongs to the Juncaceae family of rushes. The plant is native in the Americas in temperate zones but has been introduced to other parts of the world. The species is often confused with other Juncus plants due to morphological similarity. Juncus dichotomus often is found in areas which prove to be very moist, and rainfall is a common occurrence. Juncus dichotomus is often most recognizable in the spring and summer months of the year due to its conspicuous flowers and infructescence.
