HERNANDEZ-MENDOZA, Ana María; ARREGUIN-SANCHEZ, María de la Luz; GARCIA-JIMENEZ, Jesús  and  HERRERA-MONSIVAIS, María Concepción. Taxonomic composition and ecological data of the lycophytes and monilophytes from Sierra de Tamaulipas, Tamaulipas, Mexico. Polibotánica [online]. 2015, n.40, pp.29-44. ISSN 1405-2768.

In the present study are recorded a total of 18 families, 38 genera, 91 species and eight varieties of lycophytes and monilophytes. The family Pteridaceae is the most representative with (13) genera and (36) species, being the genus Cheilanthes the best represented, also recorded for first time 23 taxa for the state of Tamaulipas. We collected Schaffneria nigripes Fée, a species that had not been seen more than 30 years ago in Tamaulipas. I was found as the only species endemic to Tamaulipas Notholaena brevistipes Mickel. The examples mentioned in this paper as Anemia sp., Elaphoglossum sp. and Selaginella hansenii Hieron. vel. aff., Cheilanthes eatonii Baker vel. aff. y Ch. lozanoi (Maxon) R.M. Tryon & A.F. Tryon could be considered new species. This work includes the distribution of species by vegetation types, micro-habitats and some ecological data. We identified five vegetation types and three plant associations in the study area.

Keywords : habitat; distribution; vegetation types; altitudinal distributions.
