Selaginella biformis

A spikemoss of tropical and subtropical Asian forests, from the eastern Himalaya and southern China to the Philippines and New Guinea, growing from long-creeping rhizomes that send up branched, frond-like shoots. Collections come from shaded lowland and lower montane evergreen rainforest, sometimes over limestone. It needs shade, steady warmth and constant humidity, like most forest Selaginella.

Where it grows wild

Herbarium labels describe it as a terrestrial herb, occasionally lithophytic, in lowland evergreen and lower montane rainforest, mixed forest and forest over limestone, often along trails and streams. The rhizome is long-creeping, and it is described as frequent to occasional where it occurs.

Specimens range from about 330 m (Laos) to 1,660 m (Mount Apo, Philippines), mostly 500–1,300 m.
