- Title
Study of pollen brush in selected species ofAstragalusL. subgenusPogonophaceBunge (Leguminosae).

- Abstract
The styles of four species withinAstragalussubgenusPogonophace(Leguminosae) were investigated under the scanning electron microscope (SEM):A. hoantchyFranch.,A. complanatusBunge,A. flavovirensK. T. Fu andA. dolichochaeteDiels. The first species has a penicillate stigma, while the others possess a pollen brush. The two types of styles are not homologous. The results support the exclusion of sect.Sesbanellafrom subg.Pogonophaceand the treatment of the other three sections of the subgenus as a distinct genus (Phyllolobium) in subtribe Coluteinae (tribe Galegeae), which is consistent with previous morphological and molecular studies.
