Multistemmed, densely leafy shrub, 0.2–2.0 m high. Stems much-branched; branches erect, grey-pubescent; fascicles never present in leaf axils. Leaves alternate, spreading, 6.0– 40.0 × 0.8–2.0 mm, linear to oblong, acute to mucronate, entire to trifid, involute, narrowed into petiole-like base, without secondary basal lobes, glabrous on both surfaces, leathery; basal swelling present, continuous with stem ribs; lobes 2–3, 0.5–10.0 × 0.5–1.0 mm, linear to oblong, acute to mucronate. Capitula disciform, heterogamous, terminal, many-headed ± 30, simple to compound corymbs, pedunculate; peduncles 4.0–35.0 mm long, glabrous to white tomentose. Involucre 4.0–8.0 × 3.5–8.0 mm, hemispherical, cyathiform to urceolate, sometimes tapering at the base; involucral bracts 4- or 6-seriate, with the peduncular bracts usually being the first two series, tightly arranged, margins and apices scarious, membranous apices of all bracts 0.3–1.2 mm long, glabrous to tomentose especially along the edges, brown margins absent, median resin canals present; outer bracts lanceolate, 2.0–3.0 mm long, acute; middle bracts deltoid to lanceolate, 2.2–4.2 mm long, acute; inner bracts deltoid to lanceolate, 2.2–4.3 mm long, acute to rounded; second inner bracts deltoid to lanceolate, 3.8– 4.6 mm long, acuminate to rounded. Receptacle convex; paleae in marginal series, oblong to linear, 3.2–3.7 mm long, acute to attenuating, scarious. Filiform florets ± 20; corolla 2.3–3.0 mm long, with glandular trichomes, zygomorphic; adaxial lobes 2, 0.7–1.0 mm long, triangular, spreading, abaxial lamina 0.3– 0.6 mm long, linear, 3-dentate. Disc florets ±100, without resin canals; corolla 2.2–3.0 mm long, with only glandular trichomes, yellow; tube 1.0–2.0 mm long; limb narrowly campanulate, 0.8–1.3 mm long (excluding lobes); lobes erect to spreading,

0.4–0.6 mm long, triangular. Anthers ± 3.0 mm long (including apical appendage); apical appendage rounded to oblong. Style 2.5–3.1 mm long (excluding branches); branches 0.4–0.7 mm long. Cypselas 2.1–2.2 × 0.5 mm, obovate, 10- to12-ribbed, apical rim thickened to membranous, entire to dentate, glandular trichomes present, sparse, scattered, not mucilaginous when soaked, discontinuous resin canals in ribs absent. Figure 15 View FIG .

Diagnostic Characters — Phymaspermum athanasioides was previously considered to be a part of a complex with P. bolusii and P. montanum , distinguished by apparent differences in their involucral bracts. However, upon further study, these characters were found to be highly variable and no clearly recognisable characters could be found to distinguish between them. As a result only a single variable species, P. athanasioides , is recognised here. It is readily distinguished from all other species in the genus by the marginal filiform florets and from the other species with corymbosely arranged capitula by the absence of fascicles in the leaf axils and by the mostly entire leaves, which rarely become 2- or 3-fid.

Distribution and Ecology — Phymaspermum athanasioides is widely distributed from around Harrismith in KwaZulu Natal to Musina in Limpopo and extending into Swaziland and further north into Zimbabwe ( Fig. 15G View FIG ). It grows in mixed bushveld and grassland, especially on quartzite or sandstone, at an altitude of 1,000 m to 1,750 m. Flowering time is throughout the year but especially in August, hence its vernacular name August Gold.
