Description
Angie Zuleidi Mayorquin and co-authors chase the scent schedule of a twilight passionflower in 2026. Passiflora pohlii opens at dawn, smells strongly of citrus, and relies on crepuscular Ptiloglossa bees. The team located its scent glands, timed its emissions, and read its perfume chemistry across the morning.
Outer crown filaments house the osmophores, the scent-making tissue, and emissions peaked exactly at dawn before collapsing by 90 percent later in anthesis while flowers still looked fresh. Microscopy showed scent-cell organelles breaking down in step with the fade. Monoterpenes ruled the bouquet, led by geraniol and its kin, a package tuned tightly to one bee's size, senses, and flight hour.
