Juncus capitatus is a species of rush known by the common names dwarf rush and leafybract dwarf rush. It is native to Europe, Asia and North Africa. It is also an introduced species in parts of North America such as California and the Gulf Coast. It grows in moist areas, such as wet sand, vernal pools, and ditches. This is a small annual herb not exceeding ten centimeters in height. The stems are erect and thready, flat or somewhat corrugated. The leaves are basal and up to 3 or 4 centimeters long.
