Section Gireoudia - page 1

This program must have several, more than 10, of the species mentioned, to be effective. The more plants and the greater the variety, the better. The benefit to the program attendees will be in seeing the wide variation in plant structure that is represented by this one section. Plants should be passed around the room so that everyone has a chance to handle each plant and note its characteristics.
