Adiantum granvilleanum

A maidenhair described in 2017 from French Guiana, named after the botanist Jean-Jacques de Granville. It is known from very few collections and GBIF has no wild records with coordinates, so the climate here was taken at a regional point in French Guiana. Grow it like other lowland Guianan rainforest Adiantum: warm, shaded and humid.
