Resumen:
The pollen of Cliococca selaginoides (Lam.) C. M. Rogers & Mildner and eight Linum L. Argentinean species was examined using light and scanning electron microscopy. Both genera share pollen grains 3-zonocolpate, isopolar, radiosymmetric, spheroidal and medium to large in size. The sculptural elements of the exine are gemmae or clavae, which allowed the genera to be distinguished and the species studied to be characterized. In Cliococca Bad., the pollen is exclusively gemmate whereas in Linum the pollen is gemmate and clavae (except in L. catharticum L. whose pollen has only gemmae apically microechinate). The statistical analyses of quantitative and qualitative morphological characteristics are performed. A key to identify and distinguish the pollen types and sub-types is also provided. A Generalized Procrustes Analysis (GPA) of joint characterization based on both qualitative and quantitative characters identified four distinct groups.
