It is known by several common names, including black-banded rabbitbrush, Mojave rabbitbrush, [5] and punctate rabbitbrush. [6] [7] The stems often have black, gummy bands. [7]

Description

Ericameria paniculata is a branching shrub reaching up to 2 meters (80 inches) tall. The spreading or erect stems are glandular and resinous and are often banded or splotched with black from a smut fungus Puccinia splendens . [8] The glandular leaves are filiform (thread-shaped or narrowly oblanceolate) up to 3.5 centimeters (1.4 inches) in length. [6]

The inflorescence is an array of small, yellow flower heads, each of which contains 5 to 8 disc florets but no ray florets. The fruit is up to a centimeter (0.4 inches) long including its long pappus. They are wind-dispersed. [9] [6] [10]

It flowers from June to December. [7]

Range and habitat

Ericameria paniculata is native to the deserts of Arizona, Nevada, southern California, southwestern Utah. It is particularly common in the Mojave Desert. [9] [11] [12]

It is found in a great variety of habitats, including disturbed areas such as roadsides. It tolerates poor soils. Its companions may include Larrea tridentata (creosote), Yucca brevifolia (Joshua tree), Baccharis , Hymenoclea salsola (white burrobush), Atriplex polycarpa (desert saltbush), and Acacia greggii (catclaw acacia).
