| A revision is presented of a mainly New Guinean group of species of the genus Bulbophyllum (Orchidaceae) that is generally known as section Hymenobractea. Altogether 7 named taxa have been attributed to this section by previous authors; in this revision only two species are distinguished: Bulbophyllum aemulum and Bulbophyllum infundibuliforme. It appears that Hymenobractea cannot be distinguished from Bulbophyllum sect. Intervallatae (including sect. Dialeipanthe and sect. Lepidorhiza), therefore these two species are included in sect. Intervallatae. A key to the sections morphologically similar to Intervallatae, viz. Leopardinae, Sestochilos and Stenochilus, is included and full information on the two species provided. |

| A revision is presented of six sections of the genus Bulbophyllum (Orchidaceae): sect. Adelopetalum (mainly occurring in Australia), sect. Lepanthanthe, sect. Macrouris, sect. Pelma, sect. Peltopus, and sect. Uncifera (all mainly occurring in New Guinea). Together these include 110 species and 9 subspecies. Fortyseven species and 4 subspecies are new; they are either described in this revision or in precursors to this revision. The genus Dactylorhynchus is reduced to Bulbophyllum. Keys to the species, as well as synonymy, descriptions and illustrations of each species are provided. Some aspects of the morphology of the plants are discussed. A cladistic analysis of each revised section is given. A method to select the closest outgroup species from a number... |

| A Chapada Diamantina localiza-se na porção norte da Cadeia do Espinhaço, tendo como vegetação típica os campos rupestres, mas ocorrendo também em matas de galeria, cerrado e caatinga, possuindo elevado grau de endemismo. O gênero Bulbophyllum Thouars é um dos maiores da família Orchidaceae com aproximadamente 1.200 espécies. No Brasil são reconhecidas cerca de 58 espécies, mas apenas cinco têm sido documentadas para o Estado da Bahia. Neste trabalho foi realizado o levantamento das espécies de Bulbophyllum da Chapada Diamantina, através de coletas e coleções de herbário. Foram encontradas 12 espécies e um híbrido natural na Chapada Diamantina, sendo oito citações novas para o estado. Bulbophyllum epiphytum Barb. Rodr., B. laciniatum (Barb. Rodr.) Cogn. e... |

| During the taxonomic revision of the Neotropical Bulbophyllum (Orchidaceae) species, a new species was discovered from Bom Sucesso, Minas Gerais State, described and illustrated here as B. hatschbachianum E. C. Smidt & Borba. This species belongs to the Neotropical section Xiphizusa (Rchb. f.) Cogn. and posses a lip epichile completely different from the related species. It is closely to B. plumosum (Barb. Rodr.) Cogn. due to its vegetative morphology, but has different flower size, color and lip epichile. In B. plumosum the epichile is thin, longer and wider than the hipochile. In B. hatschbachianum the epichile is fleshy, shortest than the hipochile, thin, and sharply narrower than the hipochile. The flowers of this new species is similar to the... |

| Hybridization between B. involutum and B. weddellii (Orchidaceae) has been first observed in the Serra do Cipó, Minas Gerais State, Brazil, the hybrid being described as B. ×cipoense Borba & Semir. In this study, allozime electrophoresis was used to test the hypothesis of occurrence of hybridization between these two species, as suggested by morphological characters, in the Chapada Diamantina, Bahia State, Brazil. The lack of a diagnostic locus does not allow definite confirmation of the natural hybridization, although this hypotheses is reinforced by the absence of exclusive alleles in the putative hybrid individuals. The existence of several different genotypes points out to either population derived from multiple hybridization events or the... |
