Selaginella arbusculoides

A spikemoss endemic to the Society Islands of French Polynesia, described by J.W. Moore in 1933 and close in form to the more widespread Selaginella arbuscula. Only two wild records exist (on Tahiti and Raiatea), so its care is inferred from its relative and the islands' wet forest.

Where it grows wild

Presumed terrestrial on shaded, damp banks and rock in humid island forest, as in its relative S. arbuscula.

No elevation data; the measured climate is coastal, but upland forest on Tahiti and Raiatea is cooler and wetter.
