The people in the Plant Systematics lab at San Diego State University conduct research on the evolution of
      land plants. We acquire new data from all sources: morphology, ultrastructure, cytology, embryology,
      palynology, and DNA. Our research goals have three foci:

  1) inferring the phylogenetic relationships of plant groups and using that pattern of evolutionary history
      to study character evolution, biogeography, ecology, and evolutionary process;
  2) investigating the delimitation of plant species and infraspecies, especially in evaluating rare and
      endangered taxa;
  3) discovering and documenting the plant species and community structure of local regions in floristic studies.
