Dissection of Floral Pollination Syndromes in Petunia

I skimmed a scientific paper from genetic.org called "Dissection of Floral Pollination Syndromes in Petunia". It discusses animal.mediated pollination and how it is important for the reproductive ways of many plants that have flowers. Many of these pollination systems display complex traits and are convergent, meaning the evolved separately but display many of the same structural features. This paper focuses on the genus Petunia and describes the complez syndromes for P. axillaris, the nocturnal hawkmoth, and P. integrifolia, dirunal bees. Differences in petal color, corolla shape, reproductive organ morphology, amount of nectar, and scent were studied.
