Selaginella cataractarum

A south Indian spikemoss whose name means 'of waterfalls'; S. agastyamalayana from the Agasthyamalai hills of the southern Western Ghats is treated as a synonym. It grows on wet rocks in spray and seepage, so it needs constantly wet, well-aerated conditions rather than the hot, dry climate the single measured record suggests.
