Overview of Final Exam 2 hour time period
100 pts (1 hour) of questions based on new
material - detailed IDing of new
families/genera - new terminology (grasses
etc.) - new concepts (e.g., domestication) 50
pts (1/2 hour) of questions based on all
materials - important concepts and
terminology (see handouts, go over
lectures) - comparisons/IDing across all plants
to know

Two new groups since Exam 2
Asterids (19 genera, 9 major families)

• Major Families
• Boraginaceae (2)
• Solanaceae (1)
• Scrophulariaceae (3)
• Lamiaceae (1)
• Apiaceae (1)
• Asteraceae (3)
• Caprifoliaceae (Linnaea)

• Other Genera
• Dodecatheon (Primulaceae)
• Campanula (Campanulaceae)
• Cornus (Cornaceae)
• Philadelphus (Hydrangeaceae)
• Phlox
• (Polemoniaceae)

4
Two new groups since Exam 2
Monocots (8 genera, 6 major families)

• Major Monocot Families
• Liliaceae (2)
• Iridaceae (1)
• Orchidaceae (1)
• Poaceae (2)
• Cyperaceae (1)
• Juncaceae (1)

5
Strategy

• Know the features of major taxon groups
• Organize plants-to-know by functional categories
• Within a category, further subdivide into
  families
• Within families with multiple genera, know how to
  distinguish genera
• gt use the family tables to study!!!
