Pasaccardoa jeffreyi Wild [family COMPOSITAE], in Kirkia 8: 168; 193 (1972).— Lisowski, Aster. Fl. Afr. Centr. [in Fragm. Flor. Geobot.36, Suppl. 1]: 538 (1991). Type from Angola.
Information
An erect suffrutex, or one or more stems decumbent, from a woody rootstock. Stems annual, single or 2–4, 25–85 cm. tall, becoming woody below, branching above or sometimes throughout its length, leafy, angular-striate, thinly-lanate becoming puberulous; branches ascending. Leaves subsessile, mostly 3–10(13) x 0.5–3 cm., oblanceolate, obtuse to rounded at the apex and narrowly cuneate below, margins serrulate with minute callose teeth, upper surface thinly araneose-lanate soon roughly puberulous, lower surface greyish araneose-lanate, both surfaces densely gland-dotted. Capitula many, solitary and terminal on leafy short ascending branches, capitula subtended and usually exceeded by 1-several small leaf-like bracts. Involucre mostly 16–22(25) x 18–30 mm., spreading to c. 40 mm. wide, broadly campanulate to obconic. Phyllaries numerous; the outer straight or ± squarrose, from c. 5 mm. long, pungent-subulate, aristate, araneose-lanate; the inner straight, up to c. 23 mm. long, linear-lanceolate, tapering to a sharply acute sometimes aristate apex, tomentellous-puberulous, margins sharply minutely toothed. Receptacle deeply alveolate with pits to c. 2 mm. deep, paleae absent. Ray-florets neuter; corollas deep-red, up to c. 18 mm. long including the ray, deeply cleft; ray erect, c. 17 x 3.5–6 mm. long, oblanceolate, 3-fid, sparsely glandular outside; ovary rudimentary 5–7 mm. long, slightly swollen in lower part; pappus of many chartaceous narrowly lanceolate scales 0.5–3 mm. long. Disk-florets deep-red, tubular in the lower 2–3 mm. and abruptly dilated into a deeply lobed cylindric to conic limb 5–7 mm. long; lobes to c. 6 mm. long, linear, recurved at apex, glandular outside; anther-tube red-purple, the conical dp exserted. Achenes 5–6 mm. long, subcylindric, 10-ribbed with numerous long stiff white hairs ± appressed in the grooves, those near the achene base shorter, more robust and spreading; pappus several-seriate of numerous spreading, narrowly lanceolate, chartaceous scales 0.5–3 mm. long.
Habitat
Miombo woodland and wooded grassland, on hillsides or on Kalahari Sand.
Distribution
Zambia N Mwinilunga Distr., Lisombo R. tributary, 14.vi.1963, Loveridge 984 (K; SRGH).
Distribution (external)
Angola
Zaire
Notes
Pasaccardoa jeffreyi subsp. kasaiensis Lisowski, recorded for Angola and Zaire, is recognised by its distinctive capitula with strongly recurved phyllaries.
