Type: South Africa: [KwaZulu-Natal], hills near Blinkwater, 21 Apr. 1890, Wood 4315 (K, holo. – image!; BM – image!, BOL – image, E – image!, NH – image!, PRE – image, iso.).
Multi-stemmed shrub 0.45–1.0 m, resprouting from a woody caudex, stems simple or densely branched from near base, branches 2–4 mm diam., densely grey woolly. Leaves, sub-erect to spreading, narrowly oblong to elliptic, 15–25 × 2–5 mm, simple to trifid or rarely 4- lobed, lobes lanceolate, 3–6 mm long, base auriculate, margins revolute, grey woolly sometimes glabrescent, coriaceous; axillary shoots absent. Capitula in dense compound corymbs 15–60 mm across, branches 15–40 mm long, inflorescence bracts linear to lanceolate, 5–10 × 1–3 mm. Involucre subglobose, 5–8 × 10–15 mm, densely whitish woolly; outer bracts ovate, 2–3 × 1–2 mm, attenuate, with dark markings apically, margins minutely serrulate. Receptacle paleate. Florets 30 to 75. Pappus of ribs extended apically into horns 0.2–0.3 mm long. Cypselas obovoid, 1–2 × 0.3–1.0 mm, prominently 8- to 10-ribbed, glabrous or sometimes with sessile glands between ribs.
