It has been recognized at the species and variety level and has also been placed in synonymy under D. oligosperma Hook. Then Dorn (1978) described D. juniperina and contrasted it to D. pectinipila and D. oligosperma. To clarify the status of these three taxa, the evaluation included field and herbarium observations and scanning electron microscope studies.
