O gênero Bulbophyllum Thouars (Orchidaceae, Epidendroideae) no Parque Nacional da Chapada dos Veadeiros, Goiás, Brasil

Abstract

Bulbophyllum is one of the largest genera of Angiosperms with 2.200 species worldwide. In Brazil, there occur 60 species of which ten are recorded in the state of Goiás. The lack of taxonomic studies including Bulbophyllum in the Cerrado Phytogeographical Domain (CPD) led us to study the genus in the Chapada dos Veadeiros National Park, one of the most preserved areas of the Brazilian CPD. Six species were recorded: B. adiamantinum, B. ciluliae, B. epiphytum, B. exaltatum, B. plumosum, and B. rupicolum. Bulbophyllum adiamantinum is a new record for Goiás. The species are described, illustrated in their diagnostic characters and allow their recognition. Comments on their distribution, ecological preferences, morphological affinities, and phenology are provided. Additionally, a dichotomous key is also presented.
