“…The flora we inventoried seems to be markedly similar to other Atlantic Forest floras elsewhere, as all recorded species indeed occur throughout this domain (sensu Ab'Saber 2000), including two regarded as endemic, Capanemia micromera (Orchidaceae) and Passiflora jilekii (Passifloraceae) (Cervi 1997, Stehmann et al 2009, Buzatto & Machado 2011. The richest families in our study site (Asteraceae, Fabaceae, Myrtaceae, Cyperaceae, Malvaceae, Orchidaceae, Rubiaceae and Solanaceae) also show high number of species in other Atlantic Forest sites (Romagnolo & Souza 2000, Rodrigues & Nave 2004, Stehmann et al 2009).…”

The flora of the Atlantic Rainforest of Mato Grosso do Sul, southwestern Brazil, has not been inventoried in spite of being the westernmost inland region of this domain. We present an inventory of the riparian flora of inland Atlantic Forest in Mato Grosso do Sul. We describe the species distribution along three habitats with contrasting flood conditions: non-flooded, seasonally flooded, and swampy forests. The inventory consisted of sampling every reproductive individual, during 12 months on 1.12 ha of plots inside a 24 ha study area. We recorded 1967 individuals of 253 species and 72 families. The most representative families in number of species were Asteraceae (27), Fabaceae (19), Myrtaceae (17), Cyperaceae (12), Rubiaceae, Solanaceae and Orchidaceae (10 each). The most abundant reproductive species were Guarea macrophylla (169 individuals), Miconia chamissois (85) and Conyza bonariensis (80). Eleven species of six families were recorded for the first time in Mato Grosso do Sul, two of them endemic to the Atlantic Forest -Passiflora jilekii and Capanema micromera. We found 119 species exclusively in non-flooded habitat, 19 in seasonally flooded habitat, and 31 in swampy forest. Guarea macrophylla was the most frequent species in swampy forest, and Gochnatia polymorpha in non-flooded. The riparian forest flora at the study site resembles the Atlantic Forest and includes wide distribution riparian species; the variation of flood conditions among habitats favors its richness. Our records add new occurrences for Mato Grosso do Sul and new distribution ranges for some plant species, what arises concern upon the local biodiversity conservation. Keywords: flood gradient, plant distribution, plant richness, riparian forest, semideciduous forest.

ResumoEste trabalho apresenta um estudo florístico das Orchidaceae de Morro do Chapéu, município pertencente à Chapada Diamantina e localizado no estado da Bahia, Brasil. Cinquenta e três espécies distribuídas em 29 gêneros foram reconhecidas no presente trabalho. Dentre os gêneros mais diversos no município destacam-se Epidendrum (cinco espécies), Gomesa (cinco), Encyclia (quatro), e Habenaria (quatro). Morro do Chapéu apresentou 25 espécies exclusivas quando comparado com outros levantamentos regionais da Chapada Diamantina, contribuindo com quatro novos registros para esta área (Galeandra beyrichii, Gomesa barbata, Habenaria josephensis e Prescottia oligantha). Quinze espécies listadas neste levantamento não ocorrem nas outras áreas do leste brasileiro comparadas, estando distribuídas apenas ao longo da Cadeia do Espinhaço. Diferenças no tipo vegetacional, extensão territorial, grau de antropização e amostragem parecem interferir na similaridade florística dessas áreas. São apresentados chave de identificação, descrições, ilustrações e comentários sobre as espécies. Palavras-chave: Chapada Diamantina, florística, orquídea, taxonomia. AbstractThis work presents a floristic survey of Orchidaceae in Morro do Chapéu, municipality situated in the Chapada Diamantina, Bahia, Brazil. Fifty three species in twenty nine genera are hereby recognized. Epidendrum (five species), Gomesa (five), Encyclia (four), and Habenaria (four) were registered as the most diverse genera in the region. Morro do Chapéu had twenty five exclusive species compared with other regional surveys in the Chapada Diamantina, contributing with four new records for this area (Galeandra beyrichii, Gomesa barbata, Habenaria josephensis and Prescottia oligantha). Fifteen species listed do not occur in other compared areas of Eastern Brazil, being only distributed over the Cadeia do Espinhaço. Differences among vegetation types, territorial ranges, anthropical degrees and samples, seem to interfere with the floristic similarity of these areas. An identification key, descriptions, commentaries and illustrations of species are provided.

“…occurs from Bolivia to Paraguay and northeastern Argentina, and is the only species never to have been collected in Brazil. In Brazil, the genus occurs in the southern and south-eastern regions, from Rio Grande do Sul (Pabst, 1972;Pabst and Dungs, 1977;Buzatto et al, 2010 to Bahia State (Buzatto and Machado, 2011).…”

A comparative survey of floral characters in Capanemia Barb. Rodr. (Orchidaceae: Oncidiinae)

With the sole exception of Capanemia therezae, all species shared a distinctive set of floral characters. Flowers were mostly white or yellowish-white and fragrant, and column wings were positioned parallel to the labellum, concealing the stigmatic cavity. Pollinaria had proportionally long tegular stipes and clavate to reniform pollinia, whereas the labellum possessed a conspicuous indument of trichomes, but was devoid of nectar or any other secretion that might function as a food-reward. Capanemia therezae, however, was exceptional in having greenish, unscented flowers with short, rounded and divergent column wings and an exposed stigmatic cavity. Its pollinaria had proportionally short tegular stipes and round pollinia, whereas the labellum lacked trichomes. Droplets of nectar were evident on the adaxial surface of the labellum, adjacent to the callus. Floral features did not support the currently accepted sectional division of Capanemia. If ongoing phylogenetic studies demonstrate that both sections are indeed monophyletic, then these taxa should be distinguished solely on the basis of foliar features.
