Resumen
n this paper of the catalogue of south brazilian arboreal pollen grains, the autor deals with the Papilionatae. The Mimosoideae and Caesalpinioideae are yet in preparation, so that a discussion of the three subfamilies (or families) is not possible. In relation with the systematical subdivision of the Papilionatae, we found a large correspondence with the morphology of the present pollen grains. The group of Phaseoleae contains the genera Mucuna, Erythrina and Dioclea; the grains of the studied species are very different one from another; the first of the genera possesses very volumous grains, with three colpori and a reticulated superficies; the second has three-porated pollen grains with a large reticulated superficies, and the third, Dioclea, is yet different; it possesses oblated grains, each three-colporated, with a thick sexine and a psilated superficies. So, we can say, that Phaseoleae is a erypalynous group. Dalbergieae, with the genera: Andira, Dalbergia, Lonchocarpus, Machaerium, Platymiscium and Pterocarpus (and Dahlstedtia, the only exception), has very uniform pollen grains, and may be considered stenopalynous. It is not possible to include the genus Dahlstedtia into this group. A little exception is represented by Pterocarpus violaceus, because of the reticulated sexine of its grains, while the others, also three-colporated, possess a tectate-reticulated sexine. The genera Myrocarpus and Ormosia, from Sophoreae, are very more similar to the Dalbergieae as to any other genus of the Phaseoleae.
