16. The taxonomic value of leaf anatomy for species Byrsonima: a difficult genus of Malpighiaceae Juss.
ABSTRACT We studied the leaf anatomy of 15 species of Byrsonima and a single species of Diacidia as an outgroup to test the relevance of leaf anatomical characters to the complicated taxonomy of this genus. We present complete anatomical descriptions for petioles and leaf blades, together with an anatomical matrix, dendrogram and an identification key for th

21. A revision and morphological analysis of the Uruguayan species of Stevia (Compositae, Eupatorieae)
Abstract A revision and a morphological analysis of the Uruguayan species of Stevia (Compositae, Eupatorieae) were performed. Leaf, inflorescence, pubescence and pappus traits were identified as key to separate species. Stevia entreriensis, S. entreriensis var. minor, and Dissothrix hassleriana were considered synonyms of S. hirsuta, and S. ophryodonta and S
