Adiantum amplum

A large maidenhair from the seasonally dry Pacific and Gulf lowlands of Mexico through Central America to Colombia and Venezuela. It lives mostly below about 700 m in forests with a hard dry season from December to April, so it likes warmth, shade and ravine-like moisture.

Where it grows wild

No detailed habitat account was reachable. Records concentrate in seasonally dry to semi-deciduous lowland forest, where maidenhairs of this size typically grow on shaded ravine banks, stream sides and moist slopes. Costa Rican data give the Caribbean lowlands at 0–100 m.

Recorded at 9–2,716 m, but the median is 489 m and most records are lowland.
