The Leptopteris is a small genus of ferns native to the New Guinea, Australia, New Zealand, and the Pacific Islands. They are similar to ferns in the related genus Todea, and were originally included in that genus. However, the very thin fronds of Leptopteris differ from the thick leathery fronds of Todea, and the genera are considered distinct.[1] A probable extinct species, Leptopteris estipularis is known from the Early Cretaceous of India.[2]
