Isocoma acradenia is a North American species of flowering plant in the family Asteraceae known by the common name alkali goldenbush.
It is native to the Southwestern United States ( California, Nevada, Utah, Arizona) and northwestern Mexico ( Sonora, Baja California). It grows in arid, sandy areas, particularly mineral-rich areas such as alkali flats and gypsum soils. [2] [3] [4] [5] [6]
Isocoma acradenia is a bushy subshrub reaching maximum heights of slightly over 1 m (39 in). It produces erect, branching stems which are a shiny pale yellowish white, aging to a yellow-gray. [7]
Along the tough, hard-surfaced stems are linear or oval-shaped glandular leaves 1–6 cm (0.39–2.36 in) long, sometimes with stumpy teeth along the edges. They are gray-green and age to pale gray or tan. [7]
The inflorescences along the top parts of the stem branches are clusters of four or five flower heads. [8] Each head is a capsule encased in bumpy, glandular greenish phyllaries bearing many golden yellow disc florets at its mouth. Each disc floret is somewhat cylindrical and protruding. [7]
The fruit is an achene a few millimeters long, with a yellowish pappus adding another few millimeters. [7]
