GOMEZ-NOGUEZ, Felipe; PEREZ-GARCIA, Blanca; MENDOZA-RUIZ, Aniceto  e  OROZCO-SEGOVIA, Alma. Palynological flora of ferns and lycophytes of Río Malila, Hidalgo, Mexico. Bot. sci [online]. 2013, vol.91, n.2, pp.135-154. ISSN 2007-4476.

Morphological characteristics of the spores of 36 species of ferns and three of lycophytes from Rio Malila, municipality of Molango de Escamilla, Hidalgo, Mexico, grouped into 27 genera and 14 families are provided. The spores of Ctenitis equestris, Elaphoglossum obscurum, Polystichum turrialbae, and Pecluma sursumcurrens are described for the first time. Palynological descriptions were based on observations of fresh material with light microscopy and/or scanning electron microscopy, images are included for each species. As a result dichotomous key for the identification of all species studied was elaborated. The palynologic knowledge of the ferns may contribute to resolve taxonomic problems in the group, to the opportune diagnose of risk populations and to facilitate aerobiological studies of the pteridophytes, like the airborne spore identification, the dispersal of spores in different weather and environmental conditions, and its possible health risk for other organisms.
