Selaginella dahlii

A New Guinea spikemoss described by Hieronymus in 1913, presumably named after the collector Friedrich Dahl, who worked in the Bismarck Archipelago. No usable wild records were found, though one site was measured, with a hot, very wet climate and no dry season. Care is inferred from lowland Melanesian Selaginella.
