Phanerosorus
Quick Summary
The genus Phanerosorus is a monotypic genus, meaning it contains only one species. This species, Phanerosorus zeylanicus, is found in Sri Lanka and extends into regions from the Himalayas to Queensland, Australia. It belongs to the family Ophioglossaceae, which are primitive ferns characterized by leaves divided into a sterile blade and a fertile spike with embedded spore-producing structures. The genus Phanerosorus is distinguished by the position and structure of its sporangia, which are found in small groups on both sides of the fertile spike. This genus is part of the order Marattiales, which includes other large, fleshy ferns found in tropical regions.12
