BARTH, Ortrud Monika  y  YONESHIGUE, Yocie. Catálogo sistemático dos pólens das plantas arbóreas do Brasil meridional: VIII - Leguminosae (Mimosoideae). Mem. Inst. Oswaldo Cruz [online]. 1966, vol.64, pp.79-111. ISSN 0074-0276.

In order to finish the study of pollen grains of arboreal Leguminosae from south brazilian rain forests, this part of our Pollen Catalogue deals with the subfamily Mimosoideae. The grains of all examined species are grouped, from tetrads (like Mimosa taimbensis) to polyads with 32 grains (like Inga lentiscifolia). In relation to the morphology of these polyads, the pollen grains from the present species were distributed in five different groups. However, these groups are not in correspondence with the five Tribus in which these species are distributed, in opposition with our observations in Papilionatae and Caesalpinioideae. We were no able to found clear separations between the pollen grains of the subfamilies studies. The tricolporated type, a little prolate, occurs frequently in the three subfamilies, whereas the Mimosoideae are caracterized by polyads. However this last subfamily may present also isolated grains.
