Plantas pequeñas de esta especie tienen hojas ovado-lanceoladas y han sido identificadas a veces como Ophioglossum petiolatum Hook., pero no se han observado plantas provenientes de Mesoamérica que se apeguen estrictamente a esa especie. Existen algunas indicaciones de que tal vez la que ha sido llamada O. petiolatum en Florida, Hawaii y otros lugares, pudiera ser una especie arvense del Viejo Mundo que se ha naturalizado. Si es así, podría posiblemente aparecer en Mesoamérica.
