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.[2] Like all narrow endemics, it is highly vulnerable to habitat destruction.[2][1]

Description

[edit]

The plant is a small, slender, perennial herb with erect, unbranched stems and narrow leaves 15 to 35 millimetres (0.59 to 1.38 in) long. Its flowers are pale greenish-yellow, 18 to 25 millimetres (0.71 to 0.98 in) 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][3]
