Rushes

Rushes are monocotyledonous plants in the genus Juncus. Rushes make up most of the species in the family Juncaceae. There are about 400 species in the rush family, distributed among eight or nine genera. The most species-rich groups are the rushes (Juncus spp.) with 225 species, and the wood-rushes (Luzula spp.) with 80 species.

Species in the rush family occur worldwide, but they are particularly abundant in moist and wet habitats of cool-temperate, boreal, arctic, and alpine zones, especially in the Northern Hemisphere.
