The pollen morphology of six species of Keiskea and three representative taxa of Collinsonia was studied in detail using LM, SEM, and TEM. In both genera, pollen grains are monad, hexa-colpate, and mostly medium in size [P = 28.0 to 37.0 ㎛, E = 24.3 to 30.7 ㎛ (Keiskea); P = 30.0 to 45.0 ㎛, E = 26.0 to 39.0 ㎛ (Collinsonia)]. Polar outlines are of circular or ellipsoid form. Shapes range from primarily oblate-spheroidal to prolate-spheroidal to subprolate, and rarely prolate in the equatorial view.
