Morphology and reproductive strategies of the gametophyte of Polypodium lepidotrichum (Fée) Maxon (Polypodiaceae)
The young prothallus of Polypodium lepidotrichum (Fée) Maxon is a short filament with four to five cells. Later on, the thallus is spathulate. The mature thallus, about eight weeks after germination, is cordate, reniform or ovate with a narrow base. Bisexual and unisexual gametophytes were produced....

| description | The young prothallus of Polypodium lepidotrichum (Fée) Maxon is a short filament with four to five cells. Later on, the thallus is spathulate. The mature thallus, about eight weeks after germination, is cordate, reniform or ovate with a narrow base. Bisexual and unisexual gametophytes were produced. Young sporophytes were observed twelve weeks after the spore were sown. It is concluded that the reproductive strategies of P. lepidotrichum include intragametophytic and intergametophytic fertilization. |

El gametofito joven de Polypodium lepidotrichum (Fée) Maxon es un filamento corto constituido por cuatro a cinco células; en una fase intermedia los gametofitos son espatulados. Los protalos maduros, formados alrededor de ocho semanas después de la germinación de las esporas, son cordiformes, reniformes u ovales con la base angosta. Se observaron gametofitos bisexuados y unisexuados. Los esporofitos jóvenes fueron evidentes después de doce semanas a partir de la siembra de las esporas. Se concluye que las estrategias reproductivas de P. lepidotrichum involucran fecundación intragametofítica e intergametofítica.
