• Family
  • Most floral variables correlated positively and significantly across species, except corolla allocation, which was largely determined by family membership and floral symmetry. (pubmedcentralcanada.ca)
  • form
  • Morphological constancy is beneficial to pollination because a constant architecture allows for higher precision (i.e. the quality of being reproducible) in pollen exchange, and stabilizing selection has rendered flower form and shape remarkably constant within species. (pubmedcentralcanada.ca)
