THE COMMON HOUR

DIALOGUE 25: Be prepared to discuss the Flowering Plants, particularly the Asteropsida (the tricolpate edudicots).  This time we will concentrate on all of the Asteropsida families that are indicated in bold type in the Basal Tricolpates, and the Core Eudicots, which include the Caryophyllids, the Rosids, and the Asterids.  Please bring all appropriate data sheets. In addition, read the following in anticipation of the dialogue:

• Origin Chapter 12
• Holt. Islands and their Lessons in Biodiversity
• All of the guide sheets that you will use with the Dicot Activity.  You will use these sheets to make sense of the plants that you will see on Friday.

Concepts and Terms for Dialogue 25 (The Flowering Plants, Eudicots): Please access the appropriate concepts and terms for the taxa covered today through the front page of the kingdom Viridiplantae.  Any of these terms could be used in the next game.
