Assignment #1:
Build a phylogenetic tree (showing all the steps) based on the morphological characters exhibited
(and listed) below. Indicate the synapomorphies, symplesiomorphies, homoplasy, and
autapomorphies (if any):
MORPHOLOGICAL CHARACTER
1. Flower (color: black or white)
2. Leaf margin (unlobed or lobed)
3. Pollen colpi (monosulcate or tricolpate)
4. Roots (less than 1 mm thick or tuberous)
5. petals (number: 3 or 5)
6. Phyllotaxy (alternate or opposite)
7. Perianth parts (separate or fused)
8. Stems (glabrous or pubescent)

INSTRUCTIONS:
1. Fill out the blank with their Dichotomous key.2. In each numbered series you should read both choices, determine which choice best applies to the Phylum. Note that some Phyla are already given as guides.3. Proceed where the key tells you to go, often skipping other steps (numbers) in between that do not apply.
