A Taxonomic Revision of Vriesea corcovadensis Group (Bromeliaceae: Tillandsioideae) with Description of Two New Species

The Vriesea corcovadensis (section Vriesea) group consists of 11 species occurring exclusively in the Brazilian Atlantic Forest. This group is defined by the presence of polystichous and distichous flowers, utriculiform rosettes, presence of stolons, and linear-triangular leaf blades with a maximum width of 1.5 cm. We present a taxonomic revision based on observation of herbarium material and living specimens. We provide the geographical distribution, etymology, phenology, and morphological illustrations of the species, in addition to new and detailed taxonomic descriptions and a key for their identification. We describe V microrachis and V. rubens and a neotype for V. rectifolia is designated. The circumscription of V triangularis remains doubtful until additional material is available for study.
