| Description: | Glabrous, leaves opposite, at base connate, crowded, linear, carnose, obtuse, ciliate, capitula terminal, solitary, sessile, involucre oblong, viscid, phyllaries mucronate (from www.kadel.cz website) Shrub to 70 cm tall. Stems much-branched, short, glabrous, grey to black, striate. Leaves opposite, clustered along stems, dark green, surface glabrous or scattered white bristly, linear, boat-shaped or somewhat keeled, to 8 × 1 mm; apex obtuse; base connate; margins white ciliate; aromatic. Capitula solitary, terminal, narrowly cylindrical, 12 – 20 × 5 – 7 mm; apex rounded in bud; base acute. Receptacle honeycombed. Phyllaries multiseriate, ovate to oblong-linear, 3 – 10 mm long, bright yellow, shiny, glabrous; midrib thickened towards apex and forming a small, recurved mucro; apex truncate, slightly emarginate; margins jagged, ciliate. Florets c. 12 – 15; corollas to 10 mm long, sparsely glandular, yellow; lobes lanceolate, subobtuse. Achenes obconical, densely villous, to 4 mm long. Pappus c. 10 mm long, yellow. (from A synopsis of the genus Pteronia (Compositae: Astereae) in Namibia including the resurrection of Pteronia quadrifaria (Kolberg, 2014)) The consistently ciliate leaf margins or keels best distinguish Pteronia mucronata from P. unguiculata, in addition to the fewer and smaller florets, achenes and shorter pappus in the latter. Specimens with sparsely ciliate margins can be mis-identified as P. unguiculata also because the distribution areas overlap. In Namibia P. mucronata is confined to higher altitudes of the south-west and the central highlands.
