Juncus bufonius, known commonly as toad rush, is a widespread flowering plant species complex in the rush family Juncaceae. [1][2] [3]

Distribution

Its native range is circumpolar throughout tropical, subtropical, subarctic, and temperate climate areas of the Northern Hemisphere and Southern Hemisphere. [1][4][5][6][7] [8] It is also widely distributed as an introduced species in suitable habitats worldwide. It grows in moist and muddy places, often in wetlands and riparian areas. [9]

In habitats where it is not native and has naturalized it may be considered a weed. The relationship of North America plants to the Eurasian Juncus ranarius is weakly delineated. [3]

Description

Juncus bufonius is an annual monocot that is quite variable in appearance. It is generally a green clumping grasslike rush, with many thin stems wrapped with few threadlike leaves. [3]

The flowers are borne in inflorescences and also in the joint where the inflorescence branches off of the stem. It is a grassy flower folded within tough bracts and sepals. [3] The blooming period is March through May. [9]
