Schematic representation of the suggested origin and evolution of present day Hymenopappus species (Turner, 1956). various taxa, as determined from degrees of specialization, are in- dicated, the factor of time for the assumed branching is not indicated. The diagram indicates that D. torulosa is morphologically the most speciahzed, or advanced, and that D. chrysantha is the most primitive. In terms of position, as determined from the morphology of the characters selected, D. torulosa
