Description
Summary:The presence of Anadenanthera colubrina var. colubrina for the Argentinean flora is confirmed. This variety is distinguished by three morphological characters: structure of the inflorescence, fruit characteristics and venation type of the folioles, being the latter very useful when studying vegetative material. The variety colubrina inhabits the same areas as var. cebil. A distribution map, illustrations and a key to identify the varieties are presented, and lectotypes are designated for Piptadenia macrocarpa and Niopa. Se confirma la presencia de Anadenanthera colubrina var. colubrina para la flora argentina. Esta variedad se distingue por tres caracteres morfológicos: la estructura de la inflorescencia, características del fruto y tipo de venación de los foliolos, siendo éste último muy eficaz cuando se estudia material estéril. La var. colubrina cohabita con la var. cebil. Se presenta una clave para identificar las variedades, ilustraciones y mapa de distribución y se designan lectotipos para Piptadenia macrocarpa y Niopa.
