Analysis of Phylogenetic Trees

Our phylogenetic trees did not agree. We based our pollen tree off of the shape, Delphinium and Alstroemeria looked similar to a football, Gypsophila did not, and based on the pollen type, Delphinium and Alstroemeria were both plates. Gypsophila was not. The surface textures of our pollens were not comparable. The only evidence that Gypsophila and Alstroemeria were more closely related was the number of apertures each of them had. Alstroemeria and Gypsophila each had one and Delphinium had three. Perhaps when it comes to looking at the evolution of plants the number of apertures is a better display of relation.
This was shocking because the Gypsophila and Alstroemeria were the most different in size as well.  The protein sequence is most likely more accurate considering our group was basing our relationships strictly on the appearance of the pollen. Our pollen grains were so diverse, there was not much else to base it on, so the protein sequence is a more reliable estimation of our plants evolution.
