Two new species of Anthurium section Xialophyllium (Araceae) from Panama

摘要

Two new species of Anthurium section Xialophyllium from Panama are described here. Both species have close affinities with Anthurium microspadix, A. davidsoniae and A. myosuroides. Anthurium monteazulense sp. nov., known only from Chiriqui Province, is characterized by its epiphytic habit, internodes somewhat longer than broad, loosely intact cataphylls, leaf blades subcordate, bullate, ovate with two pairs of basal veins and short-stipitate green to greenish yellow cylindroid spadix. The other species, Anthurium batistae sp. nov., known only from Veraguas Province, is characterized by its terrestrial habit, elongate internodes, deciduous cataphylls, leaf blades rounded at base, ovate with one pair of basal veins and prominently stipitate purplish red cylindroid spadix.
