Abstract
Wood anatomy of 27 species from Sapindales growing in Barinas state
(Venezuela) are described. Species studied belong to the following
families: Anacardiaceae, Burseraceae, Hippocastanaceae, Meliaceae,
Rutaceae, Sapindaceae, Simaroubaceae and Staphyleaceae. A notable
homogeneity was found, especially between Anacardiaceae-
Burseraceae and Meliaceae-Sapindaceae. The most important features
are the presence of mineral inclusions (crystals and/or silica)
and septate fibers. Marginal parenchyma is found in some species
of Hippocastanaceae, Meliaceae, Rutaceae, Simaroubaceae and, ocasionally,
Sapindaceae. The only species studied from Staphyleaceae
shows a big difference with the other families studied and the only
species studied of the Hippocastanaceae family have intermediate
features between Meliaceae and Sapindaceae. The segregation of
Staphyleaceae from the order Sapindales is supported by wood anatomy
traits. A dichotomous key for identification is included.
