Castilleja collegiorum explained
Castilleja collegiorum is a species of Castilleja known by the common name collegial paintbrush.
It is endemic to a single meadow complex in Oregon, where it grows in open mixed-species meadow sites.[1] Like all narrow endemics, it is highly vulnerable to habitat destruction.
Description
The plant is a small, slender, perennial herb with erect, unbranched stems and narrow leaves 15to long. Its flowers are pale greenish-yellow, 18to long, and each is subtended by a reddish bract. Other than the flowers, there is little visible difference between the inflorescence and the sterile parts of the stem below it; the bracts and foliage leaves are only weakly differentiated.[2]
