Description

La planta se llama de varias maneras por ejemplo: "Adiantopsis radiata", "Polystichum munitum" o "Pteridofito", pero es mejor conocida como helecho.
Ésta por lo general se encuentra en zonas húmedas y umbrosas, aunque hay ciertas especies que se adaptan a varios tipos de hábitats como los bosques tropicales, templados además de varios ambientes secos.
Se clasifica en:
Reino: Plantae
División: Monilophyta o Ptedophyta
Clase: Filicopsida o Pterophyta
Orden: Polypodiales
Familia: lomariopsidaceae
Género: Nephrolepis
Los helechos no poseen flores, ni fruto y sus hojas son llamadas frondas, aparte de que son de forma muy diversas y complicadas y por lo general muy grandes.
Sus primeros antecesores, las psilofitas, aparecieron en nuestro planeta en el periodo silúrico de la era paleozoica lo que mostraba era que éstas plantas primitivas no tenían tallos y hojas propiamente dichas.
Finalmente los usos de los helechos pueden ser muy variados ya que tienen un enorme potencial como plantas ornamentales
