The pollen grains of Paris L. , TrUlium L., Medeola L. and Scoliopus Torr. in Trilliaceae , and of Lilium L. and Hemerocallis L. in Liliaceae were examined by LM and SEM. The result shows that Paris, Medeola and Scoliopus have pollen characterized by monoanacolpate aperture and foveolate or reticu-late (or compound reticulate) exine sculpture . The genus TrUlium, however, has inaperturate pollen and various exine sculptures including granulate, verrucate, gemmate, starred and spinulate types, but absent of reticulate type. The pollen of Scollops is peculiar in exine sculpture by having compound reticulum supported by many thick ridges. The genera Lilium L. and Hemerocallis L. have pollen of monoanacolpate aperture and very complicated reticulate sculpture, which is similar to that of Paris, Medeola and ScoHopus. There is no obvious difference in exine stratification of pollen grains among 4 genera of Trilliaceae except the genus TrUlium which has a discontinuous foot layer, but the others have continuous and thick foot layer. There is little difference between Trilliaceae and Liliaceae in exine stratification.
