Criptógamas atribuidos a Antonio José Cavanilles (1745-1804), y su entorno, conservadas en el herbario del Real Colegio Alfonso XII (San Lorenzo de El Escorial, Madrid)/Criptogams from Antonio José Cavanilles (1745-1804) and his scene, in the herbaria of the Real Colegio AlfonsoXII (San Lorenzo de El Escorial, Madrid)

In this paper we present the study of a historical collection of 129 cryptogams, most of them identified by Antonio José Cavanilles (1745-1804), four sheets are attributable to Mariano La Gasca (1776-1839) and one of them to Luis Neé (1734-1803). These materials are kept in the Herbarium of the Real Colegio Alfonso XII of San Lorenzo de El Escorial (Madrid); the specimen collected by Luis Neé is dated in 1786; the rest of the collection lacks any information about location nor date; this fact, and the interest of Cavanilles on cryptogams during the first years of the XIX century, suggest the date of the collections between 1786 and 1804.
