Autores/as

A new natural hybrid of Catasetum is illustrated with photographic plates and described here based on collections made in the Trombetas River basin, in the municipality of Oriximiná, state of Pará (Brazilian Amazon). It is compared with the parental species (C. galeritum and C. macrocarpum), with which it shares characteristics that are clearly intermediate between these two taxa. Data relating to the habitat, ecology and geographic distribution of the hybrid described here are also presented. This finding reinforces the Amazon region as a center of diversification for Catasetum.

Se describe e ilustra con láminas fotográficas un nuevo híbrido natural de Catasetum, a partir de colecciones realizadas en la cuenca del Río Trombetas, en el municipio de Oriximiná, estado de Pará (Amazonía brasileña). Se compara con las especies parentales (C. galeritum y C. macrocarpum), con las que comparte características claramente intermedias entre estos dos taxones. También se presentan datos relativos al hábitat, ecología y distribución geográfica del híbrido descrito aquí. Este descubrimiento refuerza a la Amazonía como centro de diversificación para Catasetum.
