Pyrrosia angustata

A narrow-fronded epiphytic tongue fern of lowland Malesian forest, recorded mostly below 300 m in Borneo, Peninsular Malaysia and Sumatra. Like other Pyrrosia its thick, felted fronds handle brief drying, so it suits a warm, humid, bright mount rather than a constantly wet terrarium.

Where it grows wild

Grows on tree trunks and branches in lowland and hill rainforest, including disturbed and fairly open sites; specific microhabitat detail is thin, so this follows the genus.

Records span 10–3,429 m but the median is 160 m; it is essentially a lowland and hill-forest plant.
