Flora of the cangas of Serra dos Carajás, Pará, Brazil: Siparunaceae

We present the taxonomic treatment of Siparunaceae for the canga formations of Serra dos Carajás (Pará, Brazil). Only one species was recorded, Siparuna ficoides, taxon ocurring in Venezuela and northern Brazil. This record represents the first of this species for the state of Pará; and probably is the third known individual of the species, being the first material examined different from those described in the original work. A description, comments and illustration of the species are presented.

First record of the genus Tropidia Lindl. (Orchidaceae) for Brazil

The genus Tropidia is composed of ca. 20-30 species distributed in southern Asia, South Pacific islands and northern Australia, and a single species occurring in America, from United States to Ecuador. The first record of the genus Tropidia for Brazil is presented here. It consists of Tropidia polystachya, a species found in the Cerrado biome, Midwestern Brazil. Description, illustration, photos, and distribution map of the species are provided. Additionally, the leaf anatomy of the species was studied and it is very similar to the leaves of other species of Tropidieae described so far. DNA sequences of T. polystachya are presented (plastid matK and rbcL and nuclear ITS) in order to assist future phylogenetic studies with the genus.

Orchidaceae no município de Caldas Novas, Goiás, Brasil

Resumo O presente estudo teve como objetivo inventariar as especies de Orchidaceae ocorrentes no municipio de Caldas Novas.

Os generos que apresentaram maior numero de especies foram Epidendrum e Habenaria (seis especies cada), seguidos por Cleistes (tres), e Cyrtopodium (duas). Cinco especies listadas sao novas ocorrencias para Goias, mostrando a necessidade de inventarios floristicos no estado. Orchidaceae of Caldas Novas, state of Goias, Brazil Abstract The aim of this study was to inventory the species of Orchidaceae occurring in Caldas Novas. We conducted monthly collections during 2008 (except from September to November). Parallel to the fieldwork, surveys were done in the herbaria CEN, IBGE, UB and UFG. We present an identification key, morphological descriptions, comments and illustrations of the species. We recorded 15 genera and 28 species of Orchidaceae in the area. The genera with more species were Epidendrum and Habenaria (six species each), followed by Cleistes (three), and Cyrtopodium (two). Five species are new records for the state of Goias, showing that floristic inventories in the state are still needed.
