Minutes of Pullman Workshop on Angiosperm Phylogeny
May 2-3, 1999
Washington State University
Pullman, WA

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 funding.

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.

  1. coordination within symposia and among symposia
  2. updating of data availability matrices
  3. terminology; examples of words that are often misused or misinterpreted:
  4. Data analysis
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.
