This plant is native to much of North America except for northern Canada and southern Mexico. It is usually found in moist areas in sandy and gravelly substrates. It may be annual or perennial. It grows narrow green stems sometimes reaching heights exceeding 1.5 meters. The leaves at the nodes are small, scale-like brownish sheaths and there are occasionally small, spindly branches. The stems are topped with rounded cone-shaped sporangia.
