C. Presl (Hemidictyaceae). El registro extiende su área geográfica hacia el norte, estableciendo a Veracruz como el límite septentrional de distribución de la especie en México. Se brinda una descripción, un mapa de distribución en el país, así como ilustraciones con fotografías. Esta especie crece en lugares pantanosos, anegados, humedales y bosques lluviosos, en especial en orillas de arroyos.]]></p></abstract>
