Morphogenesis of the sexual phase of seven epiphitic taxa of Polypodium (Polypodiaceae) from Mexico
Morphology of the sexual phase of seven epiphytic taxa of Polypodium that grow in Mexico was observed and described. The spores of all species studied are monolete, ellipsoid to reniform, and verrucate to tuberculate. All the species analyzed have the Vittaria-type pattern of germination. In regard...

| description | Morphology of the sexual phase of seven epiphytic taxa of Polypodium that grow in Mexico was observed and described. The spores of all species studied are monolete, ellipsoid to reniform, and verrucate to tuberculate. All the species analyzed have the Vittaria-type pattern of germination. In regard to the prothallial development, the Drynaria-type was observed in Polypodium furfuraceum, P. plebeium, P. polypodioidesvar. aciculare, P. polypodioides var. polypodioides, whereas P. rhodopleuron. P. fraternum and P. lepidotrichum displayed the Aspidium-type pattern. Unisexual and/or bisexual gametophytes were observed in some species. Polypodium fraternum, P. furfuraceum, P. lepidotrichum, P. plebeium, P. polypodioides var. aciculare and P. polypodioides var. polypodioides developed archegonial gametophytes while P. rhodopleuron, P. plebeium and P. polypodioides var. polypodioides formed antheridial gametophytes. A trend to the vegetative propagation of the gametophytes was observed in P. lepidotrichum and P. rhodopleuron. |

Se analiza y describe la morfología de la fase sexual de siete taxa epífitos de Polypodium que crecen en México. Las esporas son monoletes, elipsoidales a reniformes, con el perisporio verrucado a tuberculado. El patrón de germinación corresponde al tipo Vittaria para todas las especies; en cuanto al desarrollo protálico, se observó el tipo-Drynaria en Polypodium furfuraceum, P. plebeium, P. polypodioides var. aciculare, P. polypodioides var. polypodioides y P. rhodopleuron y el tipo Aspidium en P. fraternum y P. lepidotrichum. Con respecto a los gametangios, en algunas especies se formaron gametofitos unisexuales y/o bisexuales. Las especies que desarrollaron protalos con arquegonios fueron P. fraternum, P. furfuraceum, P. lepidotrichum, P. plebeium, P. polypodioides var. aciculare y P. polypodioides var. polypodioides. Los anteridios se originaron en P. rhodopleuron, P. plebeium y P. polypodioides var. polypodioides. Se observaron yemas para la propagación vegetativa en los gametofitos de P. lepidotrichum y P. rhodopleuron.
