LEE, SANGTAE*, MEEKYOUNG KANG, and CHUNGHEE LEE. Department of Biological Sciences, Sungkyunkwan University, Suwon 440-746, Korea. - A palynotaxonomic study of the genus Filipendula Adans. (Rosaceae).
Pollen from 19 taxa of the genus Filipendula Adans., were
examined using light and scanning electron microscopy. The pollen
morphology supported Shimizu's system (1961) in which the genus was
classified into 3 subgenera and 4 sections. Subgen. Hypogyna is
well distinguished from the other two subgenera by lacking a thick
margined, protruded, vestibulate pore and an acutely tipped colpus
with prominent costae colpi, and subgen. Filipendula by having
large grain and pore size, and a longitudinally elliptic vestibulum.
Within subgen. Ulmaria, sect. Ulmaria is distinguished
from the other sections by having a scabrate-microechinate surface,
sect. Albicoma by having a gradually thickened colpus margin,
sect. Sessilia by having a relatively short colpus and sect.
Schalameya by lacking all these characters.
