Narrowleaf Goldenaster

Chrysopsis linearifolia is disjunct between the central and western panhandle and the central peninsula.

Biennials (rarely perennials), 30–100(–200) cm; taprooted (rarely perennating by production of basal rosettes). Stems erect (often reddish purple), usually simple, glabrous. Leaves: basal blades oblanceolate to linear, 15–70 × 1–7 mm, faces glabrous or densely woolly; proximal cauline often becoming black and twisted; cauline blades linear or linear-lanceolate to oblong, flat, slightly undulate, or twisted, bases tapering to rounded, margins entire, eciliate, occasionally undulate, apices acute, faces glabrous. Heads (4–)20–100 in subumbelliform to compact, paniculiform or loosely open corymbiform arrays. Peduncles 2–8 cm, glabrous; bracteoles 1–3, linear, glabrous. Involucres campanulate, 6–10(–12) mm. Phyllaries in 4–5 series, erect, linear-lanceolate, unequal, 0.6–1.1 mm wide, apices, acute-appressed, acuminate to long-acuminate, faces glabrous, bases of outer sparsely stipitate-glandular. Ray florets 10–30; laminae 9–12 mm. Disc florets 35–60; corollas 5–6 mm, lobes 0.5–1 mm. Cypselae (stramineous) 2–2.5 mm, 2–6-ridged (ridges golden yellow to red-brown, translucent, clavate), weakly ribbed, faces sparsely strigose to sometimes only proximally so; pappi in 3 series, outer of linear to narrowly triangular scales 0.5–1 mm, inner of 20–35 bristles 4–6 mm, inner moderately clavate. 2n = 10.

Chrysopsis linearifolia, the narrowleaf goldenaster, is a North American species of flowering plant in the family Asteraceae. It has been found only in Florida.

Chrysopsis linearifolia is a biennial herb up to 200 cm (80 inches) tall. Stems are generally unbranched and hairless. Each plant can produce as many as 100 yellow flower heads, each head with both ray florets and disc florets. The species grows in sandy and grassy locations.
