Pyrrosia lingua

The tongue fern, a creeping epiphytic and rock-dwelling fern with thick, felted, undivided fronds, widespread from the Himalaya through China to Japan and Korea. It is tough and drought tolerant, takes cool winters near freezing, and does best mounted or in a very open mix with bright filtered light.

Where it grows wild

Grows on tree trunks, mossy rocks and cliff faces in warm-temperate and subtropical evergreen forest, often in fairly exposed spots. The creeping rhizome and woolly fronds let it survive dry spells by curling.

Recorded from 25 to 1,750 m, with a median of about 245 m; mostly lowland and hill forest.
