Pyrrosia penangiana

A felt fern with thick, simple fronds that creeps over tree bark and rocks in lowland and hill forest of Malaysia, Thailand and western Indonesia. Like other Pyrrosia it tolerates short dry spells thanks to its leathery, hairy fronds, and grows well mounted in bright, warm, humid conditions.
