Description

Isocoma menziesii is a subshrub forming a matted bush reaching heights of 1–2 m (39–79 in). The erect branching stems may be hairless to woolly, are generally glandular, and vary in color from gray-green to reddish brown.[3]

The leaves are oval-shaped to somewhat rectangular, gray-green and sometimes hairy and glandular, and 1–5 cm (0.39–1.97 in) long with stumpy teeth along the edges.[3]

The abundant inflorescences are clusters of thick flower heads. Each head is a capsule with layers of thick, pointed, greenish phyllaries. The head is filled with large, protruding, cylindrical yellow disc florets with long stigmas.[3]
