Chihuahuan Brickellbush has pale yellow or greenish white floral units clustered in small heads. This species blooms from August to October. Brickellia floribunda Chihuahuan Brickellbush is a native perennial that grows up to 5 or more, one of the tallest Brickellia. The florets are discoid only and the bracts are greenish, often purple tinged and ovate to lanceolate. The fruits are blackish achenes, strigose and topped with a pappus of 30 to 35 barbed-like bristles. Brickellia floribunda Chihuahuan Brickellbush has green leaves, alternating along the stems. The leaves have 3 prominent veins or nerves from the base of the leaf. Plants grow in elevations from 3,000 to 5,500 feet and prefer habitats of rich soils of canyon bottoms, riparian areas, near streams and Pinyon Juniper communities. Species is semi-desert and upper Sonoran desert species. Brickellia floribunda

Comments: With so many species of Brickellia, Chihuahuan Brickellbush can be identified, in part by its clusters of florets, reflective of its species epithet “floribunda” or “many flowers”. According to Kearney and Peebles, Arizona Flora, 1960, the Hopi Indians would rub parts of the plant on their head to cure headaches.

In Southwest Desert Flora also see; California Brickellbush, Brickellia californica, Coulter's Brickellbush, Brickellia coulteri, and Veiny Brickellbush, Brickellia venosa.

Etymology:
The genus Brickellia is named in honor of John Brickell (1748–1809), Irish-born physician and naturalist from Savannah Georgia. The genus was named in honor of John Brickell by American botanist Stephen Elliott in one of his most important works; A Sketch of the Botany of South-Carolina and Georgia. There is little other recorded information about Dr. John Brickell. Confusion is possible as another "John Brickell" (1791-1844), also a naturalist and also from Ireland is the author of a thoroughly plagiarized 1729 publication, The Natural History of North-Carolina.

The species epithet floribunda is translated from the Latin roots "flori" and "bund" meaning "many-flowering" as reference to its clusters of flowers.
