Common name: Native Carrot
Daucus glochidiatus (Labill.) Fisch. et al. 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. Grows on alluvial plains, cracking clays, sandy or stony ground often in Astrebla grassland. NFWP; N.T., S.A., W.A. [may be close to the var. leptacanthus Thell.]|

|3||Habit compact, rosette-like with umbels compact and clustered at the base or internodes of the plant. Spines on secondary ribs of mericarps pubescent or bristly, in 2 or more irregular rows, reduced to short blunt or conical tubercles, often 2 or more fused together, apex blunt with 2 or more rows of 10–20 recurved prickles.Spines on primary ribs in more than 2 rows, hyaline.
