Yellow Poplar Tree

Caption

The evolution and diversification of the more than 300,000 living species of flowering plants may have been "jump started" much earlier than previously calculated, according to a new study led by Penn State University scientist Claude dePamphilis. The study provides a wealth of new genetic data and is expected to change the way biologists view the family trees of plants in general and flowering plants in particular. This image shows the leaves and a flower of the yellow poplar tree (Liriodendron tulipifera), a basal angiosperm included in the study led by Penn State scientist Claude dePamphilis. This plant was included in the Ancestral Angiosperm Genome Project.
