Perennial herb or woody herb, 0.3–1 m high, sometimes scrambling to 2 m, erect or sprawling, much branched; stems often decumbent and rooting at the base, glandular, thinly white- or grey-lanate, often winged with thin or broad wings. Leaves smelling of curry, linear to lanceolate or oblanceolate, 0.5–6 cm long, 0.2–1.5 cm wide, base narrowed or broad and clasping, usually decurrent into stem wings, apex acute or mucronate, glandular and scabrid-pubescent to scabrid-lanate above and glabrescent, grey-white lanate beneath. Capitula 3–5 mm long, heterogamous, many in dense rounded clusters united in their turn in terminal cymes; receptacle alveolate, fimbrillate; phyllaries closely imbricate and appressed, (narrowly) obovoid, 3–4 mm long, proximal part pale brown, distal part expanded and yellow, apex rounded or obtuse, the outermost lanate at the very base, all others glabrous, the innermost often with a glandular patch halfway. Outer florets absent (or up to 3, see note), narrowly cylindrical, 2.2 mm long; inner florets (3–)4–6, tube narrowly infundibuliform or cylindrical, (1.6–)2.2–2.4 mm long, lobes 0.3–0.4 mm long and glandular, anthers 1.1–1.4 mm long, style 2–2.5 mm long. Achenes ellipsoid, 0.5–0.7 mm long, minutely hairy; pappus white, (1.3–)2–3 mm long, coherent at base. Fig. 87/1–7.

Notes
Closely resembles H. stenopterum. H. engleri is brought into synonymy here; it looks slightly different as groups of capitula are enveloped by brown, concave bracts.Hilliard in F.S.A.: 75 (1983) states in South Africa outer florets are (1–)2–4 in number; in our area they are usually absent, except in a few Tanzanian specimens such as Graham 870, Haarer 1005 and Grimshaw 9484 (illustrated) which have 2–3 ª florets; most of the rare marginal florets with narrowly cylindrical, almost filiform tubes have five lobes and anthers. Inner florets are said to be (2–)5–11 in number; in our area this is 4–8. ADDENDUM/ERRATUM (published in Compositae - Part 3, 2005): Mwangoka collected Helichrysum odoratissimum in T 6.
