Stellung der palaeozoischen Sporengattungen im natuerlichen System

, : Stellung der palaeozoischen Sporengattungen im natuerlichen System. Palaeontologische Zeitschrift 28(3-4): 103-138

Arranges dispersed Paleozoic spores in the natural system of plant classification, on the basis of a comparison with spores found in fructifications of Paleozoic plants. In the light of the gaps and the number of uncertain forms revealed by the comparison, the importance of retaining the form-classification system for dispersed spores is discussed, as well as some problems of plant evolution raised by the study.
