PHYLOGENY OF GREEN PLANTS
Organizers: Buchheim, M. and Kenrick, P. Speakers: Chapman, R., Zechman, R., Buchheim, M., McCourt, R., Lewis, L., Kenrick, P., Rothwell, G.
The last of these summarized the first seven to some extent. In addition, the GPPRCG facilitated a Keynote Symposium that placed the green plants into the context of the rest of the tree of life, where Mishler gave an overview talk on green plants, drawing from the 8 symposia above.

PHYLOGENY OF LIFE
Organizers: Volker A. R. Huss and Brent Mishler
Speakers: Sogin, M., Hommersand, M., O'Kelly, C., Taylor, J., Mishler, B.

Finally, there were the following four symposia which are not part of the green plant effort directly, but which were facilitated by the GPPRCG to a greater or lesser extent and fed into the other summary talks in the PHYLOGENY OF LIFE symposium:

BROWN ALGAL PHYLOGENY: MORPHOLOGICAL AND MOLECULAR INSIGHTS:
