dense cluster of pollen tubes in Nothoscordum
paused at the entrance to the ovary
In the American midwest, prairie onion (Allium stellatum) blooms from late summer to early autumn while the closely related, false garlic (Nothoscordum bivalve) flowers in early spring. We compared the pollination and breeding systems of two extensive populations of both species within the same limestone glade at the Shaw Nature Reserve, Missouri (2018 and 2019).
This required recording their respective flowering periods, individual floral life-spans, and pollinator attractants.
