Abstract:
Bernardia fonsecae, endemic to Guerrero, Mexico, is described and illustrated, and habitat data are provided. Bernardia fonsecae is morphologically similar to B. mollis Lundell. They have in common long petioles, similar shape and size of the staminate braet, and a lobulate intrastaminal disc. Bernardia fonsecae differs from B. mollis in its leaf base and leaf-shape, vestiture of the adaxial surface of the leaf, vestiture of the abaxial veins, diameter of the cicatricoso-crateriform glands, position of the staminate inflorescence, and number of stamens, among other characteristics.
