Pollination Of Basalt Daisy (Erigeron Basalticus: Asteraceae), Diedra Petrina
All Master's Theses
Erigeron basalticus (basalt daisy) is a rare plant occupying a very restricted range of approximately 52 km2 in only two counties (Kittitas and Yakima) in central Washington State. Growing out of the cracks and crevices of basalt columns, the population of E. basalticus is fragmented and confined to its unique niche. The entire population consists of approximately 8,000 individuals.
This study focused on the pollination system of E. basalticus, specifically self-pollination and a determination of the most frequent insect visitors. Erigeron basalticus was determined to be primarily self-incompatible, therefore, pollinators will be important for successful pollination to occur.
