Synonyms: Daucus glochidiatus form B APNI*

Description: Erect or ascending annual herb 8–60 cm high, hispid, often branched from base.
Leaves 2-pinnate, 2–5 cm long, with ovate segments, lobes narrow-linear, hispid on primary and secondary veins and leaf edge; petiole of basal leaves about as long as lamina, slender and with a narrow sheathing base.
Umbels irregular, almost sessile or with 2–5 unequal rays; umbellules 1–6-flowered, white or pink to crimson, c. 1.5 mm diam.; involucral bracts one to a few, linear to narrow-lanceolate, often with membranous margins and/or hispid, pinnatifid; involucel bracteoles narrow, entire.
Fruit ovoid, usually 3–5 mm long, primary ribs with a row of short bristles that spread alternately on each side of the rib, the secondary ribs with hooked bristles.
Distribution and occurrence: Grows in wide variety of habitats; widespread in temperate and arid areas. All divisions; all States, New Zealand.
NSW subdivisions: NC, CC, SC, NT, CT, ST, NWS, CWS, SWS, NWP, SWP, NFWP, SFWP
Other Australian states: Qld Vic. Tas. N.T. S.A. W.A.
A number of forms have been recognized; further study is required to decide the status of these.

|1||Petals persistent on mature fruits, purplish or deep crimson; western slopes and plains.||2|
|Petals not persistent on mature fruit, pink, white or purplish; coast, tablelands, slopes and plains.||3|
|2||Spines on secondary ribs of mericarps glabrous, 6–9 per row, swollen and fused at the base, very long and attenuate distally, purple or at least darker at the apex with a ring of 4–6 recurved prickles, subcircular in cross section and appearing hollow. Spines on primary ribs hyaline, in 2 rows. Fruits 3.5–4.5 mm long. Inflorescence broadly spreading; peduncles short. Open branching habit. Grows in mallee and woodland, on sandy soils on stony or rocky hills. CWS SWS NWP SWP; Vic., S.A., W.A. [appears close to var. pachycanthus Thell.]||form D|
|Spines on secondary ribs of mericarps glabrous, 14–20 per row, very long and narrow, mostly free at base or sometimes 2 or 3 spines fused for half their length or more, tubular to laterally flattened in cross-section, apex purplish, acute, topped by 1 or more rows of 4–15 recurved prickles. Primary spines hyaline, in 2 rows of varying density. Fruit 4–4.5 mm long. Inflorescence shortly pedunculate to sessile. Open branching habit.
