The information we gathered during this experiment is that pollen size does in fact correspond with the size of the flower itself suporting our hypothesis. Gypsophila being the smallest of the flowers we observed had a measurement of 38.3 um in width. Delphiniumn the next flower we observed had a measurement of 45.1um. Alstroemeria the final flower we took notes on had a width of 81.5um. Given this information it would not be safe to say that this is true for all flowers, more experimenting would be needed

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.

Protein-sequence-based phylogeny
According to this phylogeny tree Alstroemeria and Gypsophila are more closely related than Delphinium.
Note: Gyspophila, Alstroemeria, and Delphinium were our general plant groups, but tricorne and repen, are more specific versions, that we did not use in our experiement. These sub catagories were the closest to the specific flowers we actually used available to us on the polygenetic tree maker.
