Discusión taxonómica

Phlebodium, as commonly construed, is a segregate of Polypodium s.l. It occurs in the New World tropics and subtropics and comprises about four species. The double included veins running to the sorus distinguish this small genus from species of Polypodium, which have free veins or a single included vein, if the veins are netted.A
