PALINOLOGÍA DE LOS GÉNEROS DE CACTACEAE MAIHUENIA (MAIHUENIOIDEAE) Y PERESKIA (PERESKIOIDEAE) DE ARGENTINA GRACIELA A. CUADRADO SILVINA S. GARRALLA Biología Pollen taxonomy morphology Pollen grains of five species from two genera of the subfamilies Maihuenioideae and Pereskioideae (Cactaceae) are described with the optical and scanning microscopes. Maihuenia (F.A.C.Weber) K.Schum.: M. patagonica (Phil.) Britton & Rose and M. poeppigii (Otto ex Pfeiff.) F.A.C. Weber ex K. Schum. (Maihuenioideae) and Pereskia Mill.: P. aculeata Mill., P. nemorosa Rojas Acosta and P. sacharosa Griseb. (Pereskioideae). The studied pollen grains of genera Maihuenia are prolate or spheroidal, medium or large sized, and Pereskia are all spheroidal and large sized. The apertures show variation in number: three to fourteen, colpate, with different pattern distribution and length of the colpus: Maihuenia has tricolpate grains and Pereskia 6-14 pantocolpate, some of them form syncolpos. The sculpture does not show marked differences between the species, which is microechinate and nanoechinate with perforations surrounded by a thickening. A key to determine the species of each genus is presented. 2009 artículo científico 0524-0476 https://www.redalyc.org/articulo.oa?id=685773810001 es http://www.redalyc.org/revista.oa?id=6857 Bonplandia application/pdf Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) Bonplandia (Argentina) Num.1 Vol.18
