Distinguishing Features
A small, ground-dwelling species of tundra, S. quadrilobus forms dense patches or erect to forward-leaning olive-green to brown shoots up to 3 cm long and 1.5 mm wide. The lateral leaves are attached across the axis of the stem ("transverse") and are predominantly 4-lobed, but lobe number can vary from 2-to-5, with the lobes themselves typically descending to about 1/2 the leaf length. Large underleaves can be seen with a hand lens and are composed of two narrow triangular lobes divided all the way towards the base.
