Abstract

-(Synopsis of the holoepiphyte and hemiepiphyte Orchidaceae of Floresta Nacional de Caxiuanã, Pará State, Brazil). This study reports the floristic survey of holoepiphyte and hemiepiphyte Orchidaceae in Caxiuanã National Forest, located between municipalities of Melgaço and Portel, near the Marajó area, Pará State, Brazil. Four random excursions for collecting fertile material were taken between April 2009 and November 2010. The family is represented by 33 species and 24 genera in Floresta Nacional de Caxiuanã. The most representative genera were Epidendrum, Scaphyglottis, Catasetum, Encyclia, and Polystachya; other genera were represented by only one species each.

Oncidiinae (Orchidaceae) on the great curve of the Xingu River, Pará state, Brazil

Although a detailed inventory of the Orchidaceae in the Great Curve of Xingu River region has never been accomplished, Ilkiu-Borges and Cardoso (1996) recorded 40 species of Orchidaceae in the called Xingu microregion, a much wider region which encompasses at least part of this study area.…”

“…Os estudos florístico-taxonômicos com Orchidaceae no Brasil foram em sua maioria realizados na Floresta Atlântica, devido a notável riqueza que a família apresenta para este Bioma (Koch et al 2014). Aproximadamente 8% do total de espécies de plantas vasculares que são citadas para o Domínio Atlântico pertencem à Orchidaceae (Stehmann et al 2009;Koch et al 2014).…”
