| description | This paper presents a checklist of the vascular plant species found in the upper watershed of the Savegre River (2 000-3 491 m above sea level), San Gerardo de Dota, Los Santos Forest Reserve, Cordillera de Talamanca, Costa Rica. Alpine páramo vegetation, subalpine dwarf forests, upper and lower montane cloud forests, as well as man-induced montane vegetation types such as pasturelands, fernbrakes, shrublands, secondary forests and tree plantations, were sampled. A total of 626 species in 121 families have been identified. 123 species of pteridophytes, 1 of conifers, 385 of dicots and 117 of monocots were recorded. The most diverse families are Asteraceae (57 species), Orchidaceae (51), Rubiaceae (26), Elaphoglossaceae (23), Polypodiaceae (23) and Poaceae (19), while the most species-rich genera are Elaphoglossum (23 species), Polypodium (14), Epidendrum (12), Peperomia (12), Asplenium (9), Blechnum (9) and Ocotea (9). Herbaceous plants (including ferns and allies) comprise 56.2% (352 species), whereas trees, shrubs and climbers make up 22.4% (140 species), 15.3% (96) and 6.1% (38) of the flora, respectively. Of the total number of species, 19.5% (122 spp.) are epiphytes. Four species (recently described Asteraceae and Lauraceae, as well as an Asteraceae and a Cyperaceae as yet undescribed) are new to science. The upper and lower montane mature forests and the upper montane secondary forests are the most species-rich plant communities, containing 264, 267 and 227 vascular plant species, respectively. The richness of the last is the consequence of the presence of numerous herbaceous species originally found in páramo vegetation and subalpine dwarf forest, which migrated downslope after forest conversion in the upper montane mature forest zone. The great diversity of lower montane mature forests is due to the presence of species mainly distributed at altitudes below 2 000 m above sea level reaching their uppermost limit precisely in this vegetation type. |

Este artículo presenta la lista de las especies de plantas vasculares encontradas en la cuenca superior del Río Savegre (2 000-3 491 m s.n.m.), San Gerardo de Dota, Reserva Forestal Los Santos, Cordillera de Talamanca, Costa Rica. Se muestreó la vegetación alpina del páramo, los bosques enanos subalpinos, los bosques maduros montano-altos y montano-bajos, como también las comunidades vegetales bajo influencia del hombre: los potreros, los helechales, los matorrales, los bosques secundarios y las plantaciones. Se identificó un total de 626 especies en 121 familias; de ellas 123 pertenecen a las pteridófitas, 1 a coníferas, 385 a dicotiledóneas y 117 a monocotiledóneas. Las familias más diversas son Asteraceae (57 especies), Orchidaceae (51), Rubiaceae (26), Elaphoglossaceae (23), Polypodiaceae (23) y Poaceae (19), mientras que los géneros más ricos en especies son Elaphoglossum (23 especies), Polypodium (14), Epidendrum (12), Peperomia (12), Asplenium (9), Blechnum (9) y Ocotea (9). Las hierbas (incluyendo helechos y otras pteridófitas herbáceas) comprenden 56.2% del total encontrado (352 especies), mientras que los árboles, los arbustos y los trepadores contribuyen con 22.4% (140 especies), 15.3% (96) y 6.1% (38), respectivamente. Del total, 19.5% (122 especies) corresponde a epífitas. Cuatro especies (una asterácea y una laurácea recién descritas, así como una asterácea y una ciperácea inéditas) son nuevas para la ciencia. Los bosques maduros montano-altos y bajos, y los bosques secundarios montano-altos son las comunidades vegetales más ricas, con 264, 267 y 227 especies de plantas vasculares, respectivamente. La diversidad de los últimos se debe a la presencia de numerosos componentes herbáceos de la vegetación del páramo y del bosque enano subalpino, especies que pueden migrar hacia elevaciones menores después de la tala del bosque maduro montano-alto. La gran diversidad de los bosques maduros montano-bajos está relacionada con la existencia de elementos de la flora vascular que tienen su óptimo a altitudes menores de 2 000 m y que alcanzan el límite superior de su distribución precisamente en este tipo de vegetación.
