Taxonomy

Juncus covillei was first described by Charles Vancouver Piper in Contributions from the United States National Herbarium 11: 182. 1906.[1]

Etymology

Juncus: the generic name was derived from the Latin word jungere meaning "to unite or bind", which comes from the fact that the stems join or intertwine.[2]

colvillei: the species was named in honor of American botanist Frederick Vernon Coville.

Distribution

It is native to western North America from British Columbia to Idaho to California, where it grows in moist habitat, often in forested areas. Including along lakes, rivers and streams, especially on occasionally flooded areas.[3]

The flat leaves are blue-green in color. There are 2 to 6 clusters on the plant and 3 to 7 flowers in a cluster. The flowers have six brown tepals.
