(lilies, grasses, etc.)

FIGURE 9.16. Phylogenetic relationship of some major plant groups. The angiosperms (flowering
plants) are subdivided further into several major groups, with the Monocotyledons and eudicots as
two of the most recognizable members. Ongoing molecular analyses are continuing to refine our
view of plant evolution.
