Article: Sections of some Carboniferous dispersed spores
N. F. Hughes, Mary E. Dettmann and G. Playford
Sections of microspores, some cingulate, one zonate and one saccate, are discussed and illustrated. It is shown that sections aid the elucidation of wall structures; thus diagnoses can be mere precisely written and this may eventually remove some classificatory difficulties. A sectioning technique is described.
