Acourtia wrightii, Brownfoot

Brownfoot has pink, purple, lavender or white showy, fragrant clustered flower heads. Plants bloom from June to November or later. Acourtia wrightii Brownfoot has 8 to 12 florets per head in contrast with A. thurberi which has 3 to 6 florets per head. Note in photo the linear to lanceolate bracts or phyllaries in 2 to 3 series. Acourtia wrightii Brownfoot grows erect and has multiple stems. The 1 to 5 inch leaves turn brown at the base of “foot” and thus the common name “Brownfoot”. Leaves are green, alternate and sessile with variable shapes ranging from oblong-lanceolate to elliptic-oblong. Acourtia wrightii Brownfoot is a perennial species that grows up to 2 feet or more tall. Plants prefer elevations from 1,200 to 5,000 feet or higher. They are found in both upper and lower deserts, foothills, rocky hillsides, canyons in gravel, caliche or sandy loamy soils. Acourtia wrightii

North America & US County Distribution Map for Acourtia wrightii.

Genus Information: In North America there are 5 species and 5 accepted taxa overall for Acourtia. World wide, The Plant List includes 84 accepted species names and includes a further 30 of infraspecific rank for the genus.

In the Southwestern United States: Arizona, New Mexico and Texas each have 3 species of Acourtia, California, Nevada and Utah each have 1 species. All data is approximate and subject to taxonomic changes.

Comments: The common name, Brownfoot is because of the brown color of leaves and dense hairs at the foot of the plant. Although native in both the Sonoran and Chihuahuan deserts, Brownfoot is a more eastern distributed Chihuahuan Desert species.

The very similar looking Thurber Desert Holly, Acourtia thurberi, differs from Brownfoot with having only 3 to 6 flowers per head, while Brownfoot has 8 or more. A third Acourtia species native to Arizona, the smallest of the three, Dwarf Desertpeony, Acourtia nana, grows to 6 or 10 inches high.

Etymology:
The genus Acourtia was named in the 18th century in honor of amateur botanist Mary Elizabeth Catherine Gibbes A'Court (1792-1878).

The specific epithet, wrightii is named to honor Charles Wright (October 29, 1811 – August 11, 1885), an American (Connecticut) and world-wide botanist working primarily in Texas, Cuba and Connecticut.
