Pyrrosia nummulariifolia

A small creeping epiphytic felt fern with rounded, coin-like leathery fronds, widespread from the eastern Himalaya to Borneo, Sulawesi and the Philippines. Its hairy, thick fronds tolerate brief drying, so it thrives mounted in bright filtered light with warm, humid air and quick-drying roots.
