Assignment

  • Draw and label species provided in lab
  • Make sure to label those morphological features that helped
  • you identify the sample (the characters in the key)
  • Identify & label all samples to family and genus
  • For Practice: use A Utah Flora to identify & label all samples to
  • species (other than any we determined in class together)
