It is native to the southwestern United States and Baja California, where it grows in wet spots in several types of local habitat, such as chaparral.

Description

Juncus macrophyllus is a rhizomatous perennial herb forming tufts of stems up to one meter tall. The sheaths on the basal leaves are between 1.5 to 3.4 millimeters long. The blade has a flat side towards the stem. The stem is between 1.5 to 3 millimeters wide. There are 1 to 2 thick cauline leaves. The inflorescence is an open array of many clusters of a few flowers each. The flower has several segments each about 5 millimeters long. There are a range of 8 to 30 flower clusters. The petals are bigger than the sepals. The midveins generally have red streaks. The fruit is obovoid and shiny brown. [2] The elevation it can be found in ranges from 700 to 2600 meters. The bloom period is between the months of July to October. [3]

<span class="mw-page-title-main">Juncaceae</span> 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. Despite the apparent similarity, Juncaceae are not counted among the plants with the vernacular name bulrush.
