| description | Background and Aims: Floristic studies of ferns and lycopods in the tropical forests of Mexico are scarce. The objectives of the present study were to know the richness of both groups in the tropical subdeciduous forest (BTS) of the state of Hidalgo, and compare their composition and richness at the species level with that of other regions of the country with the same type of vegetation.Methods: Collection of plant specimens was carried out in 26 localities of six municipalities with BTS of Hidalgo state. The taxonomic determination was realized up to species level. The taxonomic similarity between municipalities was estimated with cluster analysis (Sørensen and UPGMA index), and species richness among regions with an index of taxonomic diversity.Key results: In the BTS of Hidalgo, 12 families, 32 genera, 66 species and a fern hybrid were identified, as well as one family, one genera, and six species of lycopods. The families with the largest number of genera were Pteridaceae (9) and Polypodiaceae (6). The genera with the highest species richness were Anemia and Selaginella, with six species each. The widely distributed species were Adiantum tenerum and Tectaria heracleifolia (constancy of 85%). Six species were registered for the first time in the state. The floristic similarity between municipalities was high, except Huehuetla, located in the southern end of the study area. The BTS of Hidalgo occupies the third place in species per unit area (6.58/ha), within the tropical forests of the country.Conclusions: The species richness of the BTS of Hidalgo is high with respect to other regions with the same type of vegetation in Mexico, which is relevant to implement management and conservation plans, considering the high degree of deterioration of this ecosystem by human activities. |

Antecedentes y Objetivos: Los estudios florísticos enfocados en helechos y licopodios en los bosques tropicales de México son escasos. Los objetivos de la presente investigación fueron conocer la riqueza de ambos grupos en el bosque tropical subcaducifolio (BTS) del estado de Hidalgo y comparar su composición y riqueza a nivel de especie con la de otras regiones del país con el mismo tipo de vegetación.Métodos: La recolección de ejemplares se realizó en 26 localidades de seis municipios con BTS en la Huasteca Hidalguense. La determinación taxonómica fue hasta nivel de especie. La semejanza taxonómica entre municipios se estimó con análisis de agrupamiento (índice de Sørensen y UPGMA), y la riqueza de especies entre regiones con un índice de diversidad taxonómica.Resultados clave: En el BTS de Hidalgo se identificaron 12 familias, 32 géneros, 66 especies y un híbrido de helechos, así como una familia, un género y seis especies de licopodios. Las familias con mayor número de géneros fueron Pteridaceae (9) y Polypodiaceae (6). Los géneros con mayor riqueza de especies fueron Anemia y Selaginella, con seis especies cada uno. Las especies de amplia distribución fueron Adiantum tenerum y Tectaria heracleifolia (constancia de 85%). Se registraron seis especies por primera vez en la entidad. La semejanza florística entre municipios fue alta, excepto Huehuetla, situado en el extremo sur del área de estudio. El BTS de Hidalgo ocupa el tercer lugar en riqueza de especies por unidad de area (6.58/ha), dentro de los bosques tropicales del país.Conclusiones: La riqueza de especies del BTS de Hidalgo es alta con respecto a la de otras regiones con el mismo tipo de vegetación en México, relevante para implementar planes de manejo y conservación, considerando el elevado grado de deterioro de este ecosistema por las actividades humanas.
