2. Daucus pusillus Michx. (small wild carrot)

Pl. 206 g, h; Map 855

Stems 10–60(–80) cm long. Leaf blades 3–14 cm long, the ultimate segments 1–6 mm long, 0.5–1.0 mm wide. Involucre with the bracts 3–40 mm long, spreading to loosely ascending at flowering, spreading to loosely reflexed at fruiting. Rays 0.4–4.0 cm long, spreading to loosely ascending at flowering, curving upward only slightly (or not at all) at fruiting, the umbels thus remaining more or less flat-topped as the fruits develop. Involucel with the bractlets (or their lobes) linear to more commonly narrowly elliptic-lanceolate, lacking papery white margins, occasionally with very narrow, white margins toward the base, spreading to reflexed at fruiting. Flowers sessile (the central flower in each umbellet) or the stalks 1–9 mm long. Fruits 3–5 mm long, the mericarps with the flattened bristles of the winged secondary ribs minutely barbed or hooked at the tip (usually easily visible at 10× magnification). 2n=22. April–June.

Scattered in the southwestern quarter of the state; sporadic north of the Missouri River (southern and western U.S. north to South Carolina, Kansas, and Washington; Canada, Mexico).
