5. Stoebe fusca (Linnaeus) Thunberg (1800: 170) View in CoL . Seriphium fuscum Linnaeus (1753: 928) . Type:—[icon] Eupatorium ericoides capitis bonae spei in Breynius, Exot. Pl. Cent: t. 69, 1678 (lectotype, designated by Koekemoer in Jarvis & Turland (1998: 367)). The plate in Breynius (1678) was selected because it is an acceptable illustration of St. fusca showing individual capitula that can be distinguished in the synflorescence.

= Seriphium fuscum var. oligocephalum Schultz Bipontinus (1844: 694) View in CoL . Type :— SOUTH AFRICA. Tafelberg, 2000 ft., May 1838, Krauss s.n. (P!, lectotype, designated here, with a label in Schultz Bipontinus’ hand).

Taxonomic note: Linnaeus (1767) stated that Seriphium fuscum View in CoL is a synonym of Stoebe ericoides Bergius View in CoL , but in his description he mentioned that the capitula are one-flowered. Stoebe ericoides Bergius View in CoL has two florets and is now a synonym of Disparago ericoides (Bergius) Gaertner. Our View in CoL examination of the types leaves no doubt that Linnaeus made this synonymy erroneously.

Erect, small, much-branched shrubs, up to 0.3 m tall, or larger, densely entangled, up to 0.4 m tall or lowspreading, sparsely branched shrublets. Branches densely or sparsely leafy, often covered with a grey cobwebby indumentum. Leaves very variable, 2–8 mm long; ericoid; basally adpressed, upper part spreading or reflexed; straight, curling or twisting; tips mucronate or obtuse; abaxial surface cobwebby when young. Synflorescences terminal, capitula in loose globose, subglobose or funnel-shaped clusters, occasionally with some subterminal aggregations, mostly clearly distinguishable. Capitula homogamous, discoid, 1-flowered. Receptacle reduced, old receptacles covered in hairs and involucre bases so that individual capitulum stalks are not visible. Involucral bracts 13–16, bright yellow, chaffy or tinged plum-red in upper part; in several rows, outermost short, leafy, green, woolly; inner longer, slightly exceeding the sinuses of the corolla tube, scarious, with a thicker, central area and thinner margins that often tear with age, obtuse or subacute. Florets bisexual, bright pink or occasionally pale pink,

tube 4 mm long; corolla lobes spreading, 1.2 mm long. Stamens 5, apical appendages lanceolate, very often exserted from tube in mature florets; basally tailed. Style bifid, branches shorter than the corolla lobes, base very slightly swollen. Nectaries present. Cypselas indistinctly 5-ribbed, covered with adpressed, shaggy hairs; hairs tapering towards the tips. Pappus setae 15–18, a little shorter than the floret and involucre; dehiscing very tardily; setae fused at the base, with a few spreading barbs; plumose almost from the base; plumes soft, flexible, somewhat tufted at the tips. Flowering March and April, occasionally in February, May and June.

Distribution and habitat: —Western and Northern Cape, west of the meridian 20?. Figure 23 View FIGURE 23 .

Ecology: —Rocky to sandy areas in Table Mountain Sandstone soils, at elevations of 200–1400 m.

Conservation status: —Least Concern.

Notes: —This species is often very similar to Se. spiralis , but the latter has yellow florets with erect corolla lobes, whereas St. fusca has bright pink florets with spreading corolla lobes.
