| One hundred and eighty species belonging to 41 families inhabiting the Salado River Basin of the province of Buenos Aires (Argentina) were previously reported to be toxic for cattle. The purpose of this study was to provide a tool to distinguish the taxa when the plant material is desintegrated. In this way, an approach to the identification of these taxa through leaf epidermal features (anticlinal epidermal cell wall patterns, cuticular ornamentation, stomata, and hair types) is performed. A key to the 180 species as well as illustrations of diagnostic characters are given. |

| The leaf anatomical diversity of the genera Baccaurea Lour. (43 species), Distichirhops Haegens (3 species) and Nothobaccaurea Haegens (2 species) (Euphorbiaceae) is described. Two species of Aporosa and three species of Maesobotrya were examined for comparison. The following characters are important for the delimitation of species: hair types, the position of the glandular areas on the leaf margin, the hairiness and size of the glandular areas, the number of epidermal layers, the presence of (mucilage) idioblasts in the epidermis, the presence of palisade parenchyma above the vascular bundles, and the birefringence of the spongy parenchyma cell walls. However, leaf anatomy did not yield characters for distinction between the five genera studied. Phenetic... |

| ABSTRACT In this study, glandular and aglandular hairs were examined and compared numerically in the vegatative and reproductive organs of Salvia viridis, Salvia verticillata subsp. amasiaca, Salvia virgata, Phlomis pungens var. pungen, Phlomis pungens var. hispida, Stachys cretica subsp. anatolica, Stachys cretica subsp. smyrnaea, Teucrium scordium subsp. scordioides. It has been observed that all taxa which are collected Western and Northern Anatolia have glandular hairs and aglandular hairs of various shapes, size and modes of secretion. The hairs variations in eight Lamiaceae taxa were been investigated by means of numerical methods (Analysis of variance and Pearson correlation). It was also found that the results from numerical analysis of the hairs... |
