Riqueza de las familias Agavaceae y Nolinaceae en México

Abstract

Se muestra la distribución de las familias Agavaceae y Nolinaceae en América y México. Para México se determinó la presencia de 402 taxa, 342 de ellos pertenecen a los géneros Agave, Beschorneria, Furcraea, Hesperaloii, Manfreda, Polianthes, Prochnyanthes y Yucca de la familia Agavaceae, en tanto que 60 corresponden a los géneros Beaucarnea, Calibanus, Dasylirion y Nolina de la familia Nolinaceae. Se presenta también la lista actualizada de las especies de ambas familias, ordenadas alfabéticamente. Para cada taxon se señala su distribución por estado y por provincia florística. Los estados más ricos son: Oaxaca con 63 taxa, Durango con 52, Puebla con 50, San Luis Potosí y Sonora con 47 y Chihuahua con 45. En cuanto a las provincias florísticas con un número mayor de taxa están: las Serranías Meridionales, Sierra Madre Occidental y Altiplanicie. Para México, hasta el momento, se han realizado cinco floras regionales y cuatro listados florísticos, en los que se aborda el estudio de las Agavaceae y Nolinaceae a diferentes niveles. Los géneros Agave, Beaucarnea, Beschorneria, Ma11freda y Prochnyanthes han sido objeto de tratamientos taxonómicos; otros como Dasylirion, Furcraea y Polianthes se encuentran en diferentes etapas de desarrollo, en tanto que Calibanus, Hesperaloii, Nolina, Yucca y varios grupos de Agave, requieren una revisión actualizada. Se mencionan datos sobre la representación de los taxa a nivel de los dos principales herbarios de México (ENCB y MEXU), los cuales en conjunto suman 220 especies, avaladas por 3,593 ejemplares, con un promedio de 16.3 por taxon. Sin embargo, es necesario impulsar las colectas de herbario y de jardines botánicos, para no sólo respaldar los trabajos florísticos y taxonómicos, sino para apoyar investigaciones ecológicas, etnobotánicas, conservacionistas, etc. Estas acciones nos permitirán tener un conocimiento más profundo de la biología de las Agavaceae y Nolinaceae.
