Comptonia columbiana
Comptonia columbiana is an extinct fossil species of sweet fern known only from Eocene fossil leaves in British Columbia and the northwestern United States. It cannot be grown; the care fields below are left empty because no living plant exists to cultivate.
Comptonia columbiana is an extinct species of sweet fern in the flowering plant family Myricaceae. The species is known from fossil leaves found in the early Eocene deposits of central to southern British Columbia, Canada, plus northern Washington state, United States, and, tentatively, the late Eocene of Southern Idaho and Earliest Oligocene of Oregon, United States.
Comptonia columbiana was likely an understory plant during the Early Eocene Climatic Optimum and one of the floral components of a number of the Eocene Okanagan Highlands floras. The original specimens are from sites in the Allenby and Tranquille Formations, while subsequent fossil finds have spread the species to other locations in those formations, such as the Falkland flora and McAbee Fossil Beds of the Tranquille Formation and the Thomas Ranch site in the Allenby Formation. Work in other Okanagan Highlands localities has also increased the distribution of C. columbiana, with specimens reported from the Quilchena flora and the Klondike Mountain Formation of Washington state. Tuffs of the Klondike Mountain Formation had been dated to 49.42 ± 0.54 million years ago, the youngest of the Okanagan Highlands sites, though a revised oldest age of 51.2 ± 0.1 million years ago was given based on isotopic data published in 2021.
