ACKNOWLEDGEMENTS
Pollen tube staining methods were adapted for C. quamash by Jenny Van Wyk in communication with Susan Kephart. Deanna Deterding, Annie Zell, Kathleen Page, and Skyler Bennis assisted with field and lab work. We are grateful to Randy and Eric Oliver who helped supplement sites with honey bees as well as landowners who allowed us to place hives on their land. We would like to acknowledge that research took place on indigenous lands of the Washoe people (Wašišiw), and we are grateful for their stewardship. Early manuscript drafts benefited from feedback from Rachel Vannette, Louie Yang, Charlie Nicholson, Clara Stuligross, and Jake Francis. Research support was provided by a U.S. Department of Defense Graduate Fellowship, Davis Botanical Society Grants, and a UC Davis Vansell Scholarship awarded to M.L.P. Additional support was provided by National Science Foundation grant DEB1556885 awarded to N.M.W. and the UC Davis H. Laidlaw Endowment.
