          Abstract

          Como parte del inventario florístico de áreas afectadas por minería aluvial de oro y diamante en el estado Bolívar se visitaron cinco localidades entre 1992 y 1993. La actividad minera forma huecos, lagunas de lodo y colas. En cada localidad las colas se dividieron en cuatro áreas de acuerdo al sustrato y se colectaron plantas. Las primeras hierbas y sufrútices aparecieron en los bordes de las lagunas, cortes y declives. La localidad Asa-Karón presenta la mayor riqueza, seguida por Supamo-Parapapoy, El Polaco, Bochinche y Guaniamo. cyperus odoratus, c. luzulae, Fuirena umbellata, Pityrogramma calomelanos, trema micrantha y Phytolacca rivinoides son comunes a la mayoría de las localidades. Las familias con más especies son Poaceae, Cyperaceae, Leguminosae, Melastomataceae, Asteraceae, Rubiaceae, Solanaceae, Onagraceae, Bignoniaceae y Clusiaceae.

          Translated abstract

          As part of the floristic inventory of some disturbed areas for gold and diamond’s alluvial mining in Bolívar State five localities were studied during the years 1992 and 1993. Mining activities cause holes, mood ponds and tails. In each locality the tails were divided in four areas according to the substrate and the plants were collected. The first herbs and sufrutescent plants showed at edges of the ponds and holes. Asa-Karón is the richest locality, followed by Supamo-Parapapoy, El Polaco, Bochinche and Guaniamo. cyperus odoratus, c. luzulae, Fuirena umbellata, Pityrogramma calomelanos, Trema micrantha and Phytolacca rivinoides are common species at the majority of the localities. The families with more species are Poaceae, Cyperaceae, Leguminosae, Melastomataceae, Asteraceae, Rubiaceae, Solanaceae, Onagraceae, Bignoniaceae and Clusiaceae.
