Caféarvenses is an application that allows you to access information related to weed plants that frequently appear in coffee-producing areas. The application contains information on the main species of coffee weeds, such as taxonomy, morphological characters and photographs of the species. The application allows the user to select morphological attributes of the species to achieve taxonomic identification of weed plants. Caféarvenses was conceived by the Fraijanes Sub-Station of the Fabio Baudrit Moreno Agricultural Experimental Station of the University of Costa Rica.
