Capanemia (Oncidiinae: Orchidaceae) in South Region of Brazil

Abstract

Capanemia includes seven predominantly Brazilian epiphyte orchids, distributed by Uruguay, Paraguay, Northeastern Argentina, part of Bolivia and mainly areas of the South and Southeastern regions of Brazil, in humid forest between 450 to 1.400 m of altitude. A few species reach Uruguay, Paraguay, Northeastern Argentina and part of Bolivia. This work is focused in the species that occur in Southern Brazil and presents relevant synonymies, an artificial key for the identification of the species, descriptions, illustrations, geographic distribution, new record, habitat and additional comments for all the Southern Brazilian species.
