La familia Agavaceae en el Estado de Querétaro, México
A floristic study including the taxonomic identity and distribution of Agavaceae was done for Querétaro, México. In Mexico, the family Agavaceae is very important for its etnobotan ical, evolutionary, floristics and taxonomic relevance. Even that Querétaro has a high environmental diversity, the knowledge of the family was limited with previous reports of 15 species. By intensive collections, six genera and 31 species were found. Out of them, two genera (Beschorneria and Prochnyanthes) and 16 species are new reports for Querétaro. Besides, two species of Agave are new for science, and the natural distribution of Agave alboma1ginata is known for the first time. Comparing the number of species of Agavaceae per unit of area from each State in México, we conclude that Querétaro is the third more diverse state.
