Abstract
Pollen morphology of four genera, 22 species of Korean Crassulaceae has been examined with light and scanning electron microscopy. The presence/absence of the aperture margo and granules was useful characters to clarify the generic boundaries, and the shapes of the streate were significant to delineate taxonomic relationships within the genus Sedum. The pollen grains of Korean Crassulaceae were small and medium in size. Hylotelephium viviparum has the smallest pollen grains, and H. viridescens the largest. The pollen grains are tricolporate, circular in polar view and were prolate to prolate-spheroidal in equatorial shape. Korean Crassulaceae species have striate grains. The close pollen morphological relationships among Hylotelephium, Meterostachys and Orostachys species were concordant to the results based on the previous molecular and morphological studies. The results of the clustering analysis using pollen characters support the segregation of Sedum sensu lato which has been proposed by the previous authors. Within the genus Sedum, S. kamtschatium is closely related to S. middendorffianum with granules on the surface of the pollen grains. Sedum polytrichoides, a member of the Sedum, was clustered to the species of the Meterostachys, Hylotelephium and Orostachys, and needs to reexamine the taxonomic status. O. malacophyllus collected at Chungdong-Jin was significantly differ from the same species from Gampo in pollen and morphological characters.
