Foliar and stem anatomical functional traits occurrence in 35 xero-halophytic species. The varied vegetation of the salt marshes develops specific strategies to address factors that limit growth. To inquire about these adaptive mechanisms, leaf and caulinar anatomy was studied in 35 species inhabiting the Salitral de la Vidriera (Prov. Buenos Aires), using traditional histological techniques. A few species have thick cuticle while much of them have thickened walls of epidermal cells. Most leaves are amphistomatic, presenting some species protected stomata. Only three species have salt glands. There is a scarce development of sclerenchymatic tissue at leaf level, while the stems have a great proportion of sclerenchyma and collenchyma. Overall both organs have aqueous tissue. The most commonly type of leaf anatomy is isolateral mesophyll, the dorsiventral, Kranz and central structure are less frequent. Stems of three species have endodermis. Several species develop an early secondary growth, and in some is observed an atypical secondary growth by the differentiation of master cambium. In this work, which is the first morphoanatomical study in southwest salt marshes of Buenos Aires, it was found that the occurrence of functional anatomical characters is more diverse in leaves than in stems. La variada vegetación de los salitrales desarrolla estrategias específicas para enfrentar factores limitantes del crecimiento. Para indagar acerca de estos mecanismos adaptativos se estudió la anatomía foliar y caulinar de 35 especies que habitan el Salitral de la Vidriera (Provincia Buenos Aires), utilizando técnicas histológicas tradicionales. Algunas pocas especies presentan cutícula gruesa mientras que en gran parte de las mismas las células epidérmicas tienen paredes engrosadas. La mayoría de las hojas son anfiestomáticas, presentando algunas estomas protegidos. Sólo tres especies poseen glándulas de sal. El tejido esclerenquimático es escaso a nivel foliar, mientras que en los tallos tanto el esclerénquima como el colénquima alcanzan gran desarrollo. En general ambos órganos poseen tejido acuífero. En la anatomía foliar el tipo de mesofilo más frecuente es el isolateral mientras que el dorsiventral, la estructura Kranz y el céntrico resultan menos frecuentes. Tallos de tres especies presentan endodermis. En varias de las especies se observa crecimiento secundario temprano, así como también el desarrollo de un crecimiento secundario atípico por diferenciación del máster cámbium. En este trabajo, que constituye el primer estudio morfoanatómico en salitrales del sudoeste bonaerense, se comprobó que la ocurrencia de caracteres anatómicos funcionales es más diversa en hojas que en tallos.
