His guidance and knowledge on Mexican cycads were invaluable to the later creation of the Mexican National Cycad Collection of the Francisco Javier Clavijero Botanic Garden of INECOL, Xalapa, Veracruz.</p></div> 	https://treatment.plazi.org/id/2E5EF5096358FFD2B7BFFF58FD8FFA61	Public Domain	No known copyright restrictions apply.
