Selaginella longiciliata

Selaginella longiciliata is a small, creeping spikemoss from New Guinea, nearby islands and a tiny area of Cape York. Herbarium labels describe dense patches on shaded limestone cliffs, rock faces, cave mouths and boulders by waterfalls. That makes it a shade and high-humidity plant for a closed terrarium.

Where it grows wild

Specimen labels record it as an erect or creeping ground herb forming dense patches on shaded limestone, under overhanging cliffs at a cave mouth, on large boulders by falls in accumulated soil, and among granite rocks at the edge of rainforest. Collectors noted that the fronds are angled to catch light, which points to deep shade.

The labelled records are lowland, about 30–300 m, from coastal limestone cliffs in the Admiralty Islands to the foothills of Iron Range.
