Pohlia tundrae is most notable for elongate propagules within the leaf axils. These propagules have a brownish base, sometimes appearing as if there is a spiral to it, and yellowish or greenish leaf-like apices. More than one propagule is usually
when they are present in a leaf axile, though they detach very easily. The leaves are serrate at the apex and have a sinuous
costa. Pohlia tundrae is found at high elevation and can form an extensive groundcover.
Many thanks to the University of Colorado Herbarium (COLO), Erin Tripp & Dina Clark for loaning us this specimen for photography.
