Information
Soft shrub or perennial herb 0,3—1 (—1,2) m tall with one or more stems from a woody rootstock; stems glandular-villous. Leaves often crowded and larger near the base of the plant, petiolate or the upper ones subsessile; blade broadly ovate to oblong-lanceolate, 40-160 x 15-70 mm, rugose, scabrid, glandular-pubescent, lower surface markedly reticulate, apex acute to rounded, base cordate to obtuse, margin irregularly crenate to eroso-dentate. Inflor­escence of 15 or more verticils, spaced below, denser above; verticils usually 6-flowered. Calyx glandular-hispid to vil­lous, up to 12 mm long. Corolla whitish, pale blue or mauve, 15-25 (—30) mm long; tube 8-12 mm long; upper lip falcate, 7-15 mm long; lower lip often shorter than the upper.
Habitat
Linnaeus records the origin of 5. disermas as "Syria" but the type specimen (LINN 42/26), which agrees with the original description, matches the South African specimens cited above and is unlike anything from south-western Asia (see Hedge, I.e.).
Use
22. Salvia disermas L., Sp. PI. edn 2: 36 (1762); Benth. in DC, Prodr. 12: 291 (1848); Skan in F.C. 5,1: 319 (1910); Hedge in Notes R. bot. Gdn Edinb. 33: 105 (1974). Type: "Syria" (LINN, hole).
Range
Occurs in the north-central to southern districts from south-western Transvaal and northern Cape Province through the western Orange Free State and Karoo to Namaqualand and southwards to Uniondale and Swellendam, with a single record from central S.W. A./Namibia; found on sandy soil in water-courses, on limestone formations and rocky hillsides, tending to spread as a weed along roadsides, on waste places and on overgrazed veld. Map 56.
