Characteristics

Dwarf woody shrublet or suffrutex up to 1 m tall, virgately branched or with long ± simple stems when regenerating after fire, stoutest stem seen c. 5 mm in diam., pubescent all round, hairs generally c. 0.1 mm long, retrorse, rarely mixed with longer curved or curled hairs up to 0.3-1 mm long, these sparse to plentiful, closely leafy. Leaves opposite, quickly alternate, fascicled, largest primary leaves 8-25 x 1.2-3(-4.5) mm, axillary leaves similar, linear-oblong to elliptic, apex subacute and bluntly apiculate to sharply acute and sharply apiculate, base gradually contracted, subpetiolate, margins entire, slightly thickened, often revolute when dry, midrib weakly raised below, channelled above, glandular-punctate, hairs c. 0.1 mm long often present on or near margins and sometimes along midline on lower surface, rarely varying degrees of development of hairs c. 0.2 mm long on margins and both surfaces, these always associated with long hairs on stem. Inflorescence a compact corymbose panicle, sometimes compounded, composed of many few-flowered crowded spikes becoming lax in fruit, lowermost peduncles c. 15-40 mm long, nude or with a few leaves. Bract adnate to part of calyx tube, lowermost 2.8-4(-6) x 1.1-1.5(-1.7) mm, lanceolate, subacute to very acute, concave, hairs 0.1-0.15(-0.2) mm long on margins, occasionally on lower part of keel as well. Pedicel wanting. Calyx 1.6-2(-3.2) mm long, very deeply 3-lobed, anticolateral lobes ± broadly triangular (from roughly as long as broad to twice as long as broad), hairs up to 0.1 mm long on margins and outside mainly on posticous side (or rarely hairs c. 0.15 mm long and more plentiful), minutely glandular as well, inside very minute globular glands. Corolla tube 4-6 mm long, funnel-shaped, limb 5-6 mm across lateral lobes, posticous lobes 1.4-2.2 x 1.1-1.7 mm, anticous lobe 2.2-3.2 x 1-1.7 mm, all lobes oblong-elliptic, white or shades of violet-blue. Stamens: posticous filaments 1.5-2.8 mm long, anthers shortly to well exerted; anticous filaments 2-3.8 mm long, anthers far exerted. Stigma and style c. 5-7.5 mm long, style puberulous. Ovary c. 0.8 x 0.4 mm. Cocci 1.8-2.'7 x 0.8-1.1 mm, dark red-brown, rugulose. Flowers can possibly be found in any month but the main season may be August to January.
