| description | The greatest floristic diversity of the temperate forests is found in the herbaceous and shrubby component of the undergrowth, in which the flora acquires great ecological and functional importance. Essential processes of the nutrient cycle and the successional trajectory, depend directly on the vegetation of the understory. This study determined the composition and structure of the herbaceous and shrub species in dense forests of Pinus hartwegii (Lindl) and Abies religiosa (Kunth Schltdl and et Cham.) of the Nevado de Toluca and quantified the abundance of tree regeneration in 10 quadrants continuous of 10 m × 10 m. In the species smaller than 50 cm the coverage and abundance was estimated based on the Braun-Blanquet scale and, in the species greater than 50 cm, the relative value in coverage, frequency and density were obtained, besides their value of importance. According to our results, the understory of the forests of Abies religiosa is greater in diversity and is composed of 33 species, 25 genera and 14 families, where Asteraceae is the dominant family. The understory of Pinus hartwegii is composed by 18 species, 16 genera and 10 families, with dominance in coverage and abundance of the family Poaceae. In both, plant communities’ regeneration is greater in seedlings and less in small and large saplings. |

Essential processes of the nutrient cycle and the successional trajectory, depend directly on the vegetation of the understory. This study determined the composition and structure of the herbaceous and shrub species in dense forests of Pinus hartwegii (Lindl) and Abies religiosa (Kunth Schltdl and et Cham.) of the Nevado de Toluca and quantified the abundance of tree regeneration in 10 quadrants continuous of 10 m × 10 m.

La mayor diversidad florística de los bosques templados se encuentra en el componente herbáceo y arbustivo del sotobosque, en estos, la flora adquiere gran importancia ecológica y funcional. Los procesos esenciales del ciclo de nutrientes y la trayectoria sucesional, dependen directamente de la vegetación del sotobosque. Por ello, es necesario realizar la caracterización florística de estas comunidades y conocer su diversidad. En este estudio se determinó la composición y estructura de las especies herbáceas y arbustivas en bosques densos de Pinus hartwegii (Lindl) y Abies religiosa (Kunth Schltdl. et Cham.) del Nevado de Toluca y se cuantificó la abundancia de regeneración arbórea en 10 cuadrantes continuos de 10 m × 10 m. En las especies menores a 50 cm de altura se estimó la cobertura y abundancia con base en la escala Braun-Blanquet. En las especies mayores a 50 cm se obtuvo el valor relativo en cobertura, frecuencia y densidad, además del valor de importancia. De acuerdo con los resultados obtenidos, la flora del sotobosque de Abies religiosa posee una mayor riqueza y está compuesta por 33 especies, 25 géneros y 14 familias, donde Asteraceae es la familia dominante. El sotobosque de Pinus hartwegii registró un total de 18 especies, 16 géneros y 10 familias, con dominancia en cobertura y abundancia de la familia Poaceae. En ambas comunidades vegetales la abundancia de la regeneración es mayor en plántulas y menor en brinzales y latizales.
