Taxonomic notes on Pogonieae (Orchidaceae): Cleistesiopsis, a new genus segregated from Cleistes, and description of two new South American species, Cleistes batistana and C. elongata

  • Emerson R. Pansarin
  • Fábio de Barros


A new genus, Cleistesiopsis, was segregated from Cleistes based on morphological and molecular characteristics, and two new species of Cleistes: C. batistana and C. elongata, both occurring in the Brazilian Central Plateau (Central-Western Brazil), are described and illustrated. Furthermore, a key to genera currently recognised within Pogonieae is presented.

Key words

Um novo gênero, Cleistesiopsis, é segregado de Cleistes com base em caracteres morfológicos e moleculares, e duas novas espécies de Cleistes: C. batistana e C. elongata, que ocorrem no Planalto Central, no Centro-Oeste do Brasil, são descritas e ilustradas. Além disso, uma chave para os gêneros que atualmente compõem a tribo Pogonieae é apresentada.
