Minutes of Pullman Workshop on Angiosperm Phylogeny
May 2-3, 1999
Washington State University
The participants of three symposia on angiosperm phylogeny
scheduled for the 1999 International Botanical Congress
gathered for a workshop at Washington State University in
Pullman, WA, on May 2-3, 1999, organized and hosted by Pam and
Doug Soltis. A full-day (9:00 a.m. to 6:00 p.m) public
symposium was held on May 2, in which each participant
presented a preview of his/her talk for IBC. A GPPRCG Business
Meeting, chaired by Brent Mishler, was held on May 3rd.

GPPRCG Business Meeting
The meeting convened at 9:00 a.m. May 3rd, in the Compton Union
Building, Rm. 11, on the Washington State University campus;
Brent Mishler presided.
Brent thanked the speakers for their talks and the Soltises for
organizing the meeting. He then provided a brief history of
the GPPRCG and an overview of GPPRCG funding for participants
in the its 8 symposia at the International Botanical Congress.
An allocation of $1000 per talk, for each of 7 talks in each of
8 symposia, amounts to $56,000; this money will be available to
speakers on a reimbursement basis. In addition, the GPPRCG has
made 23 student travel awards--19 $500 awards and 4 $100 awards
(to cover registration). A small amount of funds have been
retained to support the website.
At the IBC, the GPPRCG will hold a breakfast and business
meeting on Thursday morning, August 5. Topics to be discusssed
are the permanent structure of the group after grant is over,
future funding, etc. The temporary Executive Committee is
composed of Brent Mishler (Chair), Mark Buchheim, Russ Chapman,
Liz Zimmer, Chuck Delwiche, and Pam Soltis.
Discussion continued about shared storage and culture
collections, funding opportunities for these facilities,
funding for collaborations, and government vs. private
Regarding publication of IBC proceedings, there is no plan at
GPPRCG level to publish symposia per se; each group can take
care of it itself; some groups do not want to publish their
proceedings because of recent publications. However, the
GPPRCG is providing a book, shortly after IBC. Editors are
Brent, Jim Doyle, and Rick McCourt. The book will be divided
into two parts: the first part (14 chapters) will contain
trees of the major clades; the second part will address
issues. Only published data will be used and discussed in the
book. All contributions to the IBC (and resulting should
acknowledg the GPPRCG grant.
The group then divided into two groups for discussion of the IBC
symposia: one group corresponded to the symposium organized by P.
Soltis, D. Soltis, and M. Chase; the second consisted of participants
in the two basal angiosperm symposis, organized by L. Zimmer and Y.-L.
Qiu and by P. Endress and E. M. Friis.
- coordination within symposia and among symposia
- revise talks?
- rearrange order? (no problem with IBC)
- how to coordinate across talks?
- some talks might need more phylogenetic context.
- seed plants need better coverage.
- integration of different types of data
- updating of data availability matrices
- Soltises will coordinate molecular data for angiosperms on DAMs;
- Brent will ask Paul Kenrick to take up Peter Crane's role for seed plants.
- terminology; examples of words that are often misused or
- Data analysis
- fewer OTUs vs. fewer characters?
- construction of data sets--fossils and morphology
- missing data--loss of support but not necessarily a change in topology
- loss of expertise in critical analyses of morphology, concern for next generation
- shallow vs. deep levels: how to proceed?
