Adiantum flabellulatum

Fan maidenhair

A widespread East and South-east Asian maidenhair with stiff, fan-like, repeatedly forked fronds on glossy dark stipes. It is common across southern China, and its range reaches Japan's Ryukyu Islands, India and Sri Lanka. It tolerates brighter, more open sites than most maidenhairs and follows a mild subtropical rhythm of warm, wet summers and cool winters.
