Revision taxonomica y tipificacion de las plantas jurasicas colectadas y estudiadas por wieland (1914) en la region de el Consuelo, Oaxaca / Таксономический пересмотр и типизация юрских растений, Виланд (1914 г.) в регионе Эль-Консуэло, штат Оахака

This publication consists of tite revision of an abundant and well preserved flora. Thís flora was collected in the region known as El Consuelo, Iocated in the Mixteca Alta, State of Oaxaca, Mexico, and studíed by Wieland in 1914. The purpose of this revision was múltiple. From the observation of the material and the Illustrations of the monograph (Wieland, 1914-1916), it is evident that Wieland applied a stríct monotypic criterion. It was necessary, taking as basis a critical analysis of the material, to define which are the vallel species and the names that would be assigned as synonims. At the same time, the lypical specimens of well identified species were selected, Another objetive of the study was tite up dating of tite taxonomy, using the pertinent modero studies and to establish with certainty tite flora's age, For the last of these goals, the stratigraphic studies of recent years in this región wece considered as well as recently made plant collections, Wieland's S3 species were reduced to 26, which are described and i1Iustrated, using the original ilIustrations of Wieland (1914-1916). The flora eonsísts of several genera of ferns (Piazopteris, Phlebopteris, Goniuosorus, Cladophlebis and Coniopteris), cycadophytes (Zamites, Otozamites, Ptllophvllum; Pterophvllum, Anomozamites, Taeniopteris, Cycaáolepis, Wüliamsonia and Perezlaria) , coniferophytes (Noeggerathiopsis, Pelourdla) and tite new genus Mexiglossa of uncertain taxonomic posltion <...>
