Adiantum giganteum

An Amazonian maidenhair described by J. Prado from northern and north-eastern Brazil. As its name suggests, it is presumably large for the genus. The records are from near sea level in a very wet, hot climate with a short dry season, so give it warmth, deep shade and constant humidity.

The three records with an elevation are all at about sea level.
