Selaginella arenaria

A South American spikemoss described by Baker in 1883, listed for Bolivia and northern Brazil. There are no wild occurrence records or measured climate; the epithet (of sand) hints at sandy ground, perhaps open sandy savanna or campina vegetation, so everything here is a low-confidence inference.
