The pollination ecology of four species of Castilleja was studied in the Berkeley Park- Yakima Park area of Mt. Rainier National Park, Washington, from 2 July to 13 August 1970. One species, C. cryptantha, was found to be self-pollinating, while the other three, C. miniata, C. oreopola, and C. rupicola, are primarily hummingbird-pollinated. Bumblebees were observed to forage on Castilleja oreopola for nectar, but a cinematographic record showed them to be too small to be effective in pollination of these plants.
