Selaginella boomii

Selaginella boomii is a rock-dwelling spikemoss of the Guiana Shield and southern Amazonia, recorded from Venezuela, Suriname and northern and central Brazil at about 110 to 650 m. Labels place it on granite and other rock outcrops: near rocky summits in terra firme forest, on rocks along streams, under overhanging rock and on wet rock at a lake edge. It needs warmth and a gritty, rocky setup rather than a peaty forest floor.
