Encyclopedia
Brickellia nevinii is a species of flowering plant in the daisy family
known by the common name Nevin's brickellbush. It is native to California
and Nevada
, where it is an uncommon resident of desert and mountain scrub plant communities.
This is an erect shrub reaching heights between 3 and 5 meters. The dense, tangling branches and foliage are coated in gray woolly fibers. The small leaves are oval to heart-shaped, toothed along the edges, and generally under two centimeters long.
The shrub flowers in clusters of flower heads
each about 1.5 centimeters long. The head is cylindrical to conical and wrapped in layers of gray woolly phyllaries
whose tips curl out from the flower head. The head contains around 23 dull white to reddish-tinted yellow disc florets that stick out from the tip. The fruit is a hairy achene
about 4 millimeters long with a pappus
of bristles.
