- In contrast, pollinator observations demonstrated that hawk moths visited flowers with larger corollas, and that the probability of producing a fruit for natural pollination plants increased with corolla diameter.
- From each plant one randomly chosen, fresh flower was dissected under a binocular microscope to separate the corolla, androecium and gynoecium.
- The internal length of the flower corolla was measured from base to opening.
