Adiantum leprieurii

A lowland maidenhair of the Guiana Shield rainforest, recorded mostly in French Guiana at 50–1000 m. Little is published on its ecology; the targets below come from the measured climate of its collection sites and the habits of rainforest-floor Adiantum. Treat it as a warm, shade-loving terrarium fern that should never dry out.
