General Information

Herbs 10-30 cm tall, annual, rosulate. Stems 1 or few, ascending to erect, simple or apically sparsely branched, glabrous, leafless or with few triangular-ovate bracts. Rosette leaves obovate to oblanceolate, 3-5 × 0.5-1.5 cm, subglabrous to hispidulous, base narrowed, margin sinuate-dentate, apex rounded to subacute. Synflorescence single-headed or weakly corymbiform with few to several capitula. Capitulum with usually 20-40 florets; peduncle long. Involucre cylindric to narrowly campanulate, 7-10 × 3-4 mm at anthesis, 1.3-1.5 mm in fruit. Phyllaries ± glabrous; outer phyllaries lanceolate; inner phyllaries linear-lanceolate. Florets yellow, slightly longer than involucre. Achene brown, dimorphic; outer achenes cylindric, 3-4 mm, ribbed, muricate, truncate; inner achenes with fusiform body, 3-4 mm, ribbed, muricate, beak capillaceous and as long as or longer than body. Pappus 7-8 mm, inner bristles plumose, outer bristles scabrid and shorter. Fl and fr. Mar-Apr. 2n = 10.

    Annuals, 10–50 cm. taproots slender, vertical; caudices small, ± herbaceous. Stems (1–30), sparingly branched at midstem or distally (lateral branches often short, minutely bracteate or naked), glabrous. Leaves usually all basal; blades oblanceolate to oblong, 20–110 × 5–30 mm, margins nearly entire to dentate or pinnatifid, faces usually glabrous or glabrate, sometimes hirsute on veins. Heads borne singly or 2–3 in loose, cymiform arrays (terminating branches, not showy) . Involucres narrowly campanulate, 8–16 × (3–)5–20 mm. Phyllaries 18–20, lanceolate, 3–18 mm, unequal, margins scarious, faces glabrous (apices brownish or reddish, sometimes ciliate). Florets 20–40; corollas white to yellowish, 5–8 mm,. equaling phyllaries at flowering. Cypselae dimorphic, outer cylindric, stout, truncate, inner fusiform, slender, beaked; bodies dark brown, 10-nerved, 8–10 mm, beaks 3–4 mm; pappi of tawny bristles in 2 series, outer barbellate, shorter than plumose inner, longest 9–10 mm. 2n = 8, 10, 12.

    "Taprooted annual or winter-annual, essentially glabrous; stem 1–4 dm, simple or sparingly branched, naked or only sparsely and minutely bracteate; basal lvs oblanceolate, toothed or pinnatifid, 2.5–15 × 0.7–3.5 cm; heads several or solitary, terminating the branches, not very showy, opening only in full sun, the ligules ca equaling the invol and only ca twice as long as wide; invol mostly 8–10 mm at anthesis, up to 17 mm in fr, its bracts imbricate; body of the achenes mostly 4–5 mm, multinerved, the nerves muricate upward; outermost achenes usually beakless, the others with a well developed slender beak; shorter outer pappus bristles commonly merely barbellate; 2n=8, 10, 12. Disturbed and waste places, especially in sandy soil; European weed, intr. in se. U.S., n. to s. Ill."

    Diagnostic Description

    Apparently not nearly so common in South Africa as H. radicata, which it closely resembles superficially, but is distinguished by its annual, not perennial, habit, in having the leaves usually glabrous, rarely somewhat hairy, the corollas about equalling the involucre, not exceeding it, and the outer achenes truncate, not beaked, all 3-4 mm long.

    Morphology

    Achenes dimorphic: those of outer florets obconic, 2.7–3.2 mm long, truncate; those of inner florets fusiform, 6.5–9.5 mm long, the distal part attenuate and beaked; both types ribbed with antrorse spinules; pappus of plumose setae 7.5–11 mm long.
