Brownplume Wirelettuce at the edge of a wash |
General: Brownplume Wirelettuce (Stephanomeria pauciflora) is an upright subshrub (doesn't really produce woody tissue) with many upright and interlocking stems arising from the base. The stems are green, and the leaves are small and inconspicuous. During spring, many white, "5-petaled" flowers are produced all over the plant.
Brownplume Wirelettuce is a common component of desert scrub
communities on flats, washes, and bajadas in the Lower Sonoran (Creosote-Bursage
Flats) and Upper Sonoran (Mojave
Desert Scrub) life zones. At higher elevations, it is less common.
Around Las Vegas, look for Brownplume Wirelettuce at Red Rock Canyon, Lake Mead National Recreation Area, Mojave National Preserve, and on the Desert National Wildlife Range.
Family: Sunflower (Asteraceae).
Other Names: skeletonweed, wirelettuce, wire-lettuce. |
Stems, reduced leaves, and a flower |
Plant Form: Many upright, interlocking branches from the base.
Height: To about 2 feet.
Stems: Upright, many stems from base. Stems smooth or dense hairy (tomentose).
Leaves: Small and inconspicuous on upper stems, often appear reduced to scales on the upper branches. Lower down, older leaves are long, narrow, with one to several points along the edges.
Flowers: Blooms in the spring and early summer, and then again in the fall if conditions permit. Inflorescence: flowers arise along upper stems. Flower is actually a sunflower type flowerhead, but without the disk in the center (i.e., ray flowers only). Usually 5 ray flowers; ray lavender-pink with square, notched tips. Phyllaries long. |

Seeds: Elongate, brownish, with feathery plumes that carry the seeds on the wind.
Habitat: Desert scrub.
Elevation: To about 8,000 feet.
Distribution: Southwestern U.S. from California to Wyoming, to Texas, and south into Mexico.
Comments: After the growing season, the plant dies back, but retains its general shape. Sometimes the base breaks off, and the plant blows in the wind like a tumbleweed.
