| description | An inventory of the angiosperm and fern plant species growing in areas deprived of trees in pastures of Los Tuxtlas mountain range is presented. In order to obtain a complete floristic list, sampling was carried out during both the dry and wet seasons of 1992, in pastures of two localities: Balzapote and La Palma. At each locality, five pastures dominated by native grass species (known locally as grama pastures) and five dominated by the introduced African star grass, Cynodon plectostachyus (known as star pastures), were selected. In each pasture ten 2 x 2 m sampling plots were randomly established within one hectare, recording the cover of every species present within each quadrat, in addition vegetation height was measured. A total of 200 angiosperm and 14 fern species, belonging to 55 families, was recorded. The families with 10 or more species were Asteraceae, Euphorbiaceae, Poaceae and Leguminosae (sensu lato). The species with cover greater than 10% of sampled area were C. plectostachyus, Axonopus spp., Paspalum conjugatum (Poaceae), Hyptis atrorubens (Lamiaceae), and Mimosa pudica (Leguminosae: Mimosaceae). Most species found in pastures were weeds and grasses; however, seedlings of tree and shrub species were also found. |

Se hizo un inventario de especies de plantas fanerógamas y pteridofitas en potreros en áreas desprovistas de árboles, en la zona del volcán San Martín Tuxtla, en Los Tuxtlas, Veracruz. Con el fin de tener la composición florística más completa posible, se realizaron muestreos durante la temporada seca y la de lluvia del año de 1992, en dos localidades: el ejido Balzapote y la colonia agrícola-ganadera La Palma. En cada localidad se seleccionaron cinco potreros dominados por especies de pastos nativas (conocidos como potreros de grama) y cinco en que prevalece la gramínea introducida Cynodon plectostachyus (llamados potreros de estrella). En cada potrero, dentro de una hectárea se ubicaron al azar 10 cuadros fijos de 2 x 2 m en los que se registró a toda planta presente y se estimó su cobertura, además de medir la altura de la vegetación dentro de cada cuadro. El resultado arrojó un total de 200 especies de angiospermas y 14 de pteridofitas, pertenecientes a 55 familias. Las familias con 10 especies o más fueron Asteraceae, Euphorbiaceae, Poaceae y Leguminosae (sensu lato). Las plantas con cobertura mayor de 10% del área muestreada fueron C. plectostachyus, Axonopus spp., Paspalum conjugatum (Poaceae), Hyptis atrorubens (Lamiaceae) y Mimosa pudica (Leguminosae: Mimosaceae). La mayoría de las especies encontradas en potreros fueron malezas y pastos; sin embargo, también se registraron plántulas de árboles y arbustos.
