  1. Utah Flora BOT2100 Lecture 5 Dicots I Including: Ranunculaceae Hydrophyllaceae Boraginaceae

  2. Utah Flora BOT2100 Dicots Flowering plants with a ovary wall (carpels) Corollas and calyx generally distinguishable sometimes one whorl is absent Flower parts in 2, 4 or 5’s Leaves generally with net-veined (branched) 2 cotyledons (1st leaves)

  20. Utah Flora BOT2100 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)
