Anatomia da madeira de duas Araliáceas da Floresta Estacional de Misiones, Argentina

Abstract

The wood anatomy of Didymopanax morototonii (Aubl.) Dcne. & Planch. and Pentapanax warmingianus (March.) Harms. are studied in their general and microscopic features. Both species share the most important anatomical features, described in the literature for the Araliaceae family. Didymopanax morototonii presents vestured and mostly scalariform pits and scalariform perforation plates in vessel members. Pentapanax warmingianus, on the other hand, does not have vestured pits and shows round or polygonal pits and mostly simple perforation plates in vessel members.
