Brickellia nevinii appears to be an incarnate form of B. microphylla. The variability in indument often makes distinguishing these species problematic. Brickellia nevinii is sometimes reported to intergrade with B. californica.

Brickellia nevinii ( 英語 )

由wikipedia EN提供

Brickellia nevinii is a species of flowering plant in the family Asteraceae known by the common name Nevin's brickellbush. It is native to southern California and Nevada, where it is an uncommon resident of desert and mountain scrub plant communities.[2][3]

Brickellia nevinii 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.[4]

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.[4]

The species is named for Rev. Joseph Cook Nevin[5]
