Implications of fossil conifers for the phylogenetic relationships of living families

  title={Implications of fossil conifers for the phylogenetic relationships of living families},
  author={Charles N. Miller},
  journal={The Botanical Review},
Fossils have played a central role in our understanding of the evolution of conifers. Interpretation of the seed cone as a compound strobilus and the homologies of the ovuliferous scales of modern conifers with the axillary dwarf shoot of Pennsylvanian forms are based on fossils. Similarly, early evolutionary trends involving the reduction, fusion, and planation of the fertile and sterile elements of the axillary dwarf shoot, leading to structures characteristic of modern families, are… CONTINUE READING
