Turkish Hawksbeard

Crepis nicaeënsis is distinguished by the annual or biennial habit, shallow root system, hispid stems, and glabrate phyllaries enclosing outer cypselae. It is similar in habit to C. biennis, which differs in its larger heads and 13–20-ribbed cypselae; it is considered closely related to C. capillaris (E. B. Babcock 1947).

Annuals or biennials, 25–110 cm (taproots shallow). Stems usually 1, erect, branched from middles or distally, densely hispidulous proximally. Leaves basal and cauline. petiolate (petioles winged, bases clasping); blades oblance-olate, runcinate, 16–19 × 2–4 cm, margins pinnately lobed, dentate, or finely denticulate, apices obtuse, faces finely hispidulous (hairs yellowish. Heads 2–15, in corymbiform arrays. Calyculi of 7–9, linear, glabrous or glabrate bractlets 3–6 mm. Involucres campanulate, 8–10 × 4–6 mm. Phyllaries 10–15, lanceolate (strongly tapered), 7–8 mm (bases strongly keeled, partly enclosing marginal cypselae, margins scarious), apices obtuse (ciliate), abaxial faces glabrous or glabrate, adaxial glabrous. Florets 50–60; corollas yellow (sometimes reddish distally), 10–11 mm. Cypselae golden brown, fusiform, 2.5–4 mm, ribs 10 (broad); pappi bright white, 4–5 mm. 2n = 8.

Crepis nicaeensis is a European species of flowering plant in the family Asteraceae with the common names French hawk's-beard and Turkish hawksbeard. It is widespread across much of Europe, as well as being sparingly naturalized in scattered locations in the United States and Canada.

Crepis nicaeensis is an annual or biennial herb up to 110 cm (44 inches) tall. One plant can produce as many as 15 flower heads, each with as many as 60 yellow ray florets but no disc florets.
