| 3. | Plant stem: Vascular bundles | Ring of primary bundles with cambium, differentiated into cortex and stele | Numerous scattered bundles in ground parenchyma, cambium mostly absent, no differentiation between cortical and stelar regions |
| 4. | Flowers | Parts in threes (trimerous) or multiples of three | Fours (tetramerous) or fives (pentamerous) |
