Abstract
Calathea hammelii and C. gloriana are described as new. They are known only from the La Selva Biological Station, Heredia Province, in the Atlantic lowlands of Costa Rica. Both species belong to Calathea section Breviscapus Benth. Calathea hammelii is most similar in flower color and morphology to C. nitidifolia from the Pacific lowlands of Costa Rica and to C. cuneata from Costa Rica and Panamá. Two morphs of C. hammelii are recognizable, differing in the sheen of the upper leaf surface. Calathea gloriana is most closely related to C. elegans from Panamá and Colombia.
