    Compositae, G. V. Pope. Flora Zambesiaca 6:1. 1992

    Habit
    An erect annual greyish-araneose herb, 8–60 cm. tall from a woody taproot.
    Stem
    Stems short, few to many-branched from near the base, sometimes apparently acaulous with rosulate basal leaves; branches ascending, simple or branching above, leafy, stout, striate-sulcate, araneose to glabrescent, pithy.
    Leaves
    Leaves spathulate to narrowly oblanceolate in outline, expanded in the apical one half to one third and ± gently tapering into a linear petiole-like base, coarsely remotely serrate or sinuate-dentate to lyrate-pinnatilobed with 2–5 lobes on each side, obtuse at the apex, semi-amplexicaul to subauriculate at the base, thinly araneose; the expanded part strongly 3(5)-nerved from near the base; basal leaves of rosulate plants crowded, mostly 10–20 x 2–4 cm., ± spathulate; upper leaves more remote, mostly up to c. 9 cm. long, oblanceolate.
    Capitulum
    Capitula many, solitary and terminal on the main and secondary branches.
    Involucre
    Involucres 12–15 mm. long and 12–20 mm. in diam., broadly cupuliform; the outer 2–3 series ofphyllaries 2–4 mm. long, produced at the apex into a ± abruptly narrowed oblong-oblanceolate appendage 2–4 mm. long, often recurved, araneose outside; inner phyllaries up to c. 13 x 6 mm., oblong usually widening towards the apex, margins scarious-hyaline to broadly so about the apex, araneose-lanate and glandular on the back except for the margins and apex.
    Receptacle
    Receptacle membranous-alveolate with the walls produced into setae to c. 4 mm. long.
    Ray
    Ray-florets; rays white or pinkish inside and blue or purplish outside, 10–30 x 1.5–4 mm., strap-shaped, 3-denticulate at the apex; achenes c. 3 mm. long, ± turbinate, truncate at the apex, at first 3-ribbed, the ribs accrescent as the achene matures becoming wing-like with the lateral wings folding around to nearly meet the central wing and so form 2 open longitudinal chambers on one face of the achene, lateral wings pale dentate-lobed on the vertical margins; pubescent-lanate on the sides with a copious tuft of straight hairs arising from the achene base and exceeding the achene in length; pappus c. 2-seriate, of delicate overlapping narrowly oblong-oblanceolate hyaline scales to c. 4 mm. long, the outer series much smaller.
    Florets
    Disk-florets very numerous; corollas blue or purplish, funnel-shaped, c. 5 mm. long; the outer 4–5 series of florets hermaphrodite producing achenes similar to those of the ray-florets; the central series ? functionally male with rudimentary ovaries. Ray-florets; rays white or pinkish inside and blue or purplish outside, 10–30 x 1.5–4 mm., strap-shaped, 3-denticulate at the apex; achenes c. 3 mm. long, ± turbinate, truncate at the apex, at first 3-ribbed, the ribs accrescent as the achene matures becoming wing-like with the lateral wings folding around to nearly meet the central wing and so form 2 open longitudinal chambers on one face of the achene, lateral wings pale dentate-lobed on the vertical margins; pubescent-lanate on the sides with a copious tuft of straight hairs arising from the achene base and exceeding the achene in length; pappus c. 2-seriate, of delicate overlapping narrowly oblong-oblanceolate hyaline scales to c. 4 mm. long, the outer series much smaller.
    Disc
    Disk-florets very numerous; corollas blue or purplish, funnel-shaped, c. 5 mm. long; the outer 4–5 series of florets hermaphrodite producing achenes similar to those of the ray-florets; the central series ? functionally male with rudimentary ovaries.
