Blechnum lenormandii

A hard fern endemic to New Caledonia, recorded from near sea level to about 1475 m, mostly around 500 m in the north and centre of Grande Terre. Little is published on its ecology, so treat it like other New Caledonian forest Blechnum: warm, humid, bright shade and steady moisture.
