Characteristics

Dwarf woody shrublet 120-350 mm tall, stems tufted from a woody taproot, erect, virgately branched, puberulous, hairs up to c. 0.1 mm long sometimes confined to margins of decurrent leaf bases, very minute globular glands as well most easily seen on young parts and peduncles, closely leafy. Leaves opposite, soon alternate upwards, fascicled or not, largest leaves 6-11 x 1.1-1.7 mm, linear-lanceolate, acute or subacute, base broad, decurrent, margins entire, thickened (often appearing revolute), texture moderately thick, venation invisible, glandular-punctate, otherwise glabrous. Inflorescence composed of racemes c. 6-8 x 6-7 mm, very congested, scarcely elongating in fruit, subsolitary, loosely panicled or more tightly corymbosely panicled (only stunted or immature specimens seen). Bract adnate to pedicel and at least half calyx tube, lowermost 3-4 x 1.4-2.3 mm, ovate, obtuse, deeply concave, hairs up to 0.15-0.25 mm long on margins, very minute glandular hairs all over both faces. Pedicels 0.2-0.5 mm long. Calyx 2-2.2 mm long, obliquely 3-lobed, anticolateral lobes roughly as broad as long, concave, much larger than posticous lobe, hairs up to 0.2-0.25 mm long on margins, very minute glandular hairs all over outside. Corolla tube 2 mm long, broadly funnel-shaped, limb 4.2-4.8 mm across lateral lobes, posticous lobes 1.2-2 x 1 mm, anticous lobe 2.2-2.3 x 1.2-1.3 mm, all lobes oblong-elliptic, shades of violet-blue. Stamens: posticous filaments 1.5-1.8 mm long, anthers well exerted, anticous filaments 2.1-2.5 mm long, anthers far exerted. Stigma and style c. 3-3.8 mm long, style glabrous or nearly so. Ovary c. 0.7 x 0.4 mm. Cocci c. 1.8-2 x 1-1.1 mm, red-brown, slightly rugulose. Of the specimens seen, one was just coming into flower in mid September, another was in first flower in November, the third being well on into fruit in early January.
