Pollen morphology of two species of cultivated Bauhinia in the Northwest of Argentina (Leguminosae: Caesalpinoideae
García, María Elena; Reyes, Nora Julieta F. 2011. “Pollen morphology of two species of cultivated Bauhinia in the Northwest of Argentina (Leguminosae: Caesalpinoideae)”. Lilloa 48 (1). In order to contribute to the knowledge of the pollen Morphology and to incorporate this material to the Pollen Atlas of the Northwest Argentine, a detailed study of MO and MEB in acetolized and natural pollen of two species of cultivated Bauhinia in the province of Tucumán is presented. We need to clarify that the mentioned Atlas contains descriptions of acetolized and natural pollen to facilitate their identification in the aeropalynologic samples. The studied species are: Bauhinia forficata Link ssp. pruinosa (Vogel) For tunato & Wunderlin and B. variegata L. In the first case, grains are 125 x 139 µm very large, oblateesferoidal, 4-6 zonocolpate, relatively short and wide colpi. Reticulate-semitectate exine of 3- 3,4 µm thick with supratectal gemmated processes. On the other hand, pollen of B. variegata presents a completely different morphology. The acetolized grains are 44 x 61 µm large, prolate to prolate-esferoidal while in the natural state they are oblate spheroidal to suboblated. In relation to the openings, they are trizonocolporated, ora lolongated of 7-10 x 2-3 µm contracted at the level of equator in the acetolized grains, while in the natural state they are prominent and slightly lolongated. They have a semitectate-striated exine of 2-2,5 µm thick.

García, María Elena; Reyes, Nora Julieta F. 2011. “Morfología polínica de dos especies de Bauhinia cultivadas en el Noroeste Argentino (Leguminosae: Caesalpinoideae)”. Lilloa 48 (1). Con el objeto de contribuir al conocimiento de la morfología polínica y de incorporar este material al Atlas Polínico del Noroeste Argentino, se presenta un detallado estudio a nivel de MO y MEB, del polen acetolizado y en estado natural de 2 especies de Bauhinia cultivadas en la provincia de Tucumán. Cabe destacar que el mencionado Atlas contiene descripciones de polen acetolizado y natural para facilitar la identificación de los mismos en las muestras aeropalinológicas. Las especies estudiadas son: Bauhinia forficata Link ssp. pruinosa (Vogel) For tunato & Wunderlin y B. variegata L. En el caso de la primera se trata de granos de tamaño muy grande, de 125 x 139 µm, oblato-esferoidales, 4-6-zonocolpados, colpos relativamente cor tos y anchos. Exina de 3-3,4 µm de espesor, reticulada, semitectada con procesos supratectales gemados. Por su parte, el polen de B. variegata presenta una morfología totalmente diferente. Los granos acetolizados son de tamaño grande de 44 x 61 µm, prolatos a prolato- esferoidales mientras que al estado natural son oblato- esferoidales a suboblatos. En relación a las aberturas, son trizonocolporados, ora lolongados de 7-10 x 2-3 µm contraídos a nivel del ecuador en los granos acetolizados, mientras que al estado natural son prominentes y levemente lolongados. Exina de 2-2,5 µm de espesor, semitectadaestriada.
