Anthurium perezfarrerae (Araceae: sect. Andiphilum), a new species from Sierra de Juárez, Oaxaca, Mexico

Mexico possesses at least 59 taxa of Anthurium , 49 species and 10 infraspecific taxa, 32 of which are found in the State of Oaxaca, Mexico. During fieldwork conducted in 2019 in Sierra de Juarez, northern Oaxaca, we discovered a previously undescribed species of Anthurium sect. Andiphilum (Schott) Croat. The new species, Anthurium perezfarrerae Diaz Jim. & Croat, is described taxonomically and illustrated. It is morphologically similar to  Anthurium  andicola Liebm. that is distributed in the same area, but this species differs in having a shorter geniculum, fewer primary lateral veins per side, tertiary vein prominolous above, and a shorter spadix.
