网页Pollen grains of Symplocos tinctoria (L.F.) L'Her. were examined by scanning and transmission electron microscopy. It was revealed that this species has a thin tectum, distinct columella layer, and developed rugulate supratectal ornamentation. The surface is densely covered by minute papillae.
Pollen morphology of JapaneseSymplocos (Symplocaceae)
网页In the present study the pollen morphology of all 23 species from Japan is investigated. All species but S. confusa (subgenus Eusymplocos or Symplocos) are assigned to subgenus Hopea sensu Brand; therefore, for more critical comparison between species groups, I follow Brand's subgeneric classification in the following descriptions and discussions.
