The PC met in plenary most of the day to introduce the remainder of the PC18 documents. In the morning, the PC heard reports on regional activities, the PC/AC transport working group and trade in Agavaceae. For the rest of the day, the PC heard and discussed working group reports. They adopted a variety of recommendations, including on: not using source code 'R' for plant species; maintaining Decisions 14.133 and 14.134 related to Orchid annotations; and prolonging the work of the Bigleaf Mahogany Working Group, widening its mandate to include cedar and rosewood. PC Chair Clemente adjourned the plenary session just after 5:00 pm, allowing for the Working Group on cedar to continue its discussions.
