Myrovernix intricata (Levyns) Koekemoer comb. nov.

Basionym:— Stoebe intricata Levyns (1937: 21) .

Type:— SOUTH AFRICA. Western Cape. Prince Albert, Levyns 5034 (BOL!, holotype).

Taxonomic note:— Levyns (1937) described this species under Stoebe , because of the predominantly single-flowered capitula. All other characters (glandular leaves, shape and colour of disc florets, cypsela morphology and short-spined pollen grains), clearly places it in Myrovernix .

Intricately branched, bushy shrubs, up to ± 1 m tall and about the same in diam., occasionally wider when scrambling over rocks. Main branches up to 15 mm diam.; secondary and tertiary branches often perpendicular to main branches, stems densely or sparsely tomentose with a dense covering of stalked glands rising above the tomentum. Leaves glandular, mostly adpressed, oblong-lanceolate, up to 3 mm long, slightly gibbous near the apex, somewhat cobwebby or almost glabrous; leaf glands very different from those on stems, up to 0.5 mm in diam., widely spaced and wart-like, glands towards the leaf base much smaller, slender and stalked, very much like glands on stems; gland stalks very short, longer towards leaf bases. Capitula homogamous, discoid, 1-flowered (rarely 2-flowered), in small groups of 5–12 capitula, both lateral and terminal. Receptacle small, conical, bare. Involucral bracts in several rows, the outer bracts short, leafy and glandular, woolly or almost glabrous; the inner bracts brown, scarious, acute, equal to or slightly shorter than the florets. Disc florets ± 3 mm long, deep purple; lobes small, erect, triangular, reflexed at maturity. Cypselas smooth, with ± 10 inconspicuous ribs. Pappus setae ± 20, slightly joined at the base, as long as the corolla. Flowering March to May.

Diagnostic features: —Leaf glands wart-like, widely spaced; innermost involucre bract tips acuminate, capitula 1-flowered.

Conservation status: —Least Concern (http://Redlist.sanbi.org).

Distribution and habitat: — Western Cape. Rocky mountain slopes. Elevations 700–1 100 m. Figure 13 .
