Plants 15–50 cm. Stems erect to spreading, green when young, becoming tan, branched proximally, often with scattered, crinkled hairs and short- stipitate-glandular hairs. Leaves mostly erect or ascending; blades oblanceolate to narrowly spatulate, 20–40 × 2–3(–5) mm, midnerves evident, apices acute to acuminate, faces short-stipitate-glandular, sometimes gland-dotted (sessile), resinous; axillary fascicles of 1–7 reduced leaves often proximally present, distally absent. Heads usually in paniculiform or cymiform arrays, sometimes borne singly. Peduncles 1–15 mm (bracts 0–3, usually resembling phyllaries). Involucres narrowly campanulate, 12–15 × 4.5–5.5 mm. Phyllaries 18–24 in (3–)4 series, tan, ovate or lanceolate to elliptic, 4–11 × 0.6–1.2 mm, subequal, mostly chartaceous, midnerves raised, evident, apices acute to cuspidate, herbaceous-tipped, abaxial faces resinous. Ray florets 0. Disc florets 10–16; corollas 9.1–11.5 mm.

Ericameria compacta is a branching shrub up to 50 cm (20 inches) tall. Leaves are oblanceolate to narrowly spatulate, up to 4 cm (1.6 inches) long. One plant can form many small, yellow flower heads, each with as many as 16 disc florets but no ray florets.
