Distichium is a plant of high elevation rock crevices, but it may even be found on wet soil in alpine sites. It can be identified by the combination of subulate leaves on an erect and unbranched plant. The shiny nature of the exposed leaf bases make the two-ranked leaf arrangement especially obvious.
