5. Inulanthera montana (Wood & Evans) View in CoL KällersjÖ in Nord. J. Bot. 5 (6): 539 (1986).
Athanasia montana Wood & Evans in Na t. Colon. Herb. Annual Rep. 10. (1900); Wood in J.Bot.171 (1901); Hilliard, Compositae in Natal: 338 (1977).
Type: South Africa, [KwaZulu-Natal], Drakensberg, source of Bushman's River, Jun. 1896, Evans 662 (NH, lecto. – image!, designated here; BOL!, K – image!, PRE – image! isolecto.).
Multi-stemmed shrub 0.30–1.0 m, resprouting from a woody caudex, stems simple or densely branched from near base, branches 2–6 mm diam., cobwebbed. Leaves sub-erect to spreading, lanceolate to obovate, 10–25 × 4–10 mm, base cuneate, margins sharply serrate, revolute, glabrous, coriaceous; axillary shoots developed in upper leaves. Capitula in dense compound corymbs 30–40 mm across, branches 5–20 mm long, inflorescence bracts linear to lanceolate, 2–10 × 3–5 mm. Involucre subglobose, 3–5 × 3–7 mm, glabrescent or glabrous; outer bracts ovate to elliptic, 2–3 × 1–2 mm, obtuse, margins serrulate. Receptacle paleate. Florets 40 to 50. Pappus formed by ribs extended apically into horns 0.1–0.3 mm long. Cypselas obovoid, 1.5–2.0 × 0.5–1.0 mm, prominently 8- to10-ribbed, scabrid. Fig. 10 View Fig .
Diagnostic characters
Inulanthera montana can be confused with I. leucoclada because of its serrated leaves, but is distinguished by the low branching habit and conspicuous axillary shoots ( Fig. 10A View Fig ) and the smaller capitula 3–7 mm long containing 40 to 50 florets (vs. 7–10 mm long containing 60 to 70 florets).
Distribution, ecology and phenology
Inulanthera montana is known mainly from central KwaZulu-Natal, where it occurs on rocky slopes in grassland at altitudes above 1700 m, with a single isolated early record from the Winterberg in Eastern Cape. Flowering is from May to July. ( Fig. 9 View Fig ).
