| Resumo: |
Pollen morphology of eight species of Cyclanthera and three species of Sicyos was studied using light and scanning electron microscopy. Pollen grains of Cyclanthera have a mean polar diameter of 51.40 µm, and an equatorial mean diameter of 49.10 µm, a prolate spheroidal shape (P/E = 1.11), 4-7 zonocolporate, with circular endoapertures, and punctitegilate exine. Pollen grains of Sicyos have a mean polar diameter of 50.60 µm and a mean equatorial diameter of 61.30 µm, an oblate spheroidal shape (P/E = 0.88), 8-12 colpate, supra and microreticulate echinate exine. Differences among the genera and species are discussed.
