Adiantum rivularis

A maidenhair fern described in 2017 from French Guiana, known from a single georeferenced wild record. As the name suggests it is associated with streams in lowland rainforest; nothing is published on its cultivation, so this profile combines the measured lowland climate with how Guianan forest-floor Adiantum grow.

Where it grows wild

Terrestrial on shaded, humid ground in lowland Guianan rainforest; the epithet (of streams) points to stream banks and wet ravine sides. Microhabitat detail beyond that is not documented.

The one recorded site is near sea level (about 20 m).
