Ecological anatomy of Bacopa species (Gratioleae-Plantaginaceae): aquatic macrophytes of the Iberá Macrosystem

Most Bacopa species (Gratioleae-Plantaginaceae) are macrophyte plants with a series of morphological, anatomical, and eco-physiological adaptations in their vegetative organs. We studied the vegetative anatomy of five Bacopa species present in the Iberá Macrosystem, and one species of Paraguay wetla...

Aerenchyma taxonomy trichomes vegetative anatomy Aerénquima anatomía vegetativa taxonomía tricomas Most Bacopa species (Gratioleae-Plantaginaceae) are macrophyte plants with a series of morphological, anatomical, and eco-physiological adaptations in their vegetative organs. We studied the vegetative anatomy of five Bacopa species present in the Iberá Macrosystem, and one species of Paraguay wetland. To study leaf and cauline anatomy, paradermal and transverse sections were made with freehand and rotating microtome from previously fixed material. The anatomical studies showed differences between the Bacopa species analyzed concerning the leaf: types of trichomes; types, distribution, and the density of stomata; and mesophyll type. In terms of the stem, two patterns of cortical aerenchyma were characterized, which are related to the environments inhabited by the species and their adaptations. As a conclusion, a dichotomous key was elaborated with vegetative anatomical characters of the Bacopa species that grow in wetlands. La gran mayoría de las especies de Bacopa (Gratioleae-Plantaginaceae) son plantas macrófitas que presentan una serie de adaptaciones morfológicas, anatómicas y ecofisiológicas en sus órganos vegetativos. Se estudió la anatomía vegetativa de cinco especies de Bacopa presentes en el Iberá y una de humedales del Paraguay. Para el estudio de la anatomía foliar y caulinar se realizaron cortes paradermales y transversales a mano alzada y con micrótomo rotativo a partir de material previamente fijado. Se encontraron diferencias entre las 6 especies de Bacopa analizadas, en la hoja relacionadas a: tipos de tricomas; tipos, distribución y densidad de estomas; y en el tipo de mesofilo. Para el tallo, se caracterizaron dos patrones de aerénquima cortical que se relacionan con los ambientes que habitan las especies y sus adaptaciones al mismo. A modo de conclusión se elaboró una clave dicotómica con caracteres anatómicos vegetativos de las especies de Bacopa que crecen en los humedales.
