Stems brown, prostrate, decumbent or erect, bifariously hairy, rarely more than 30 cm tall. Leaves narrow-lanceolate to ovate to rhomboid, widest between petiole and middle, usually shallowly toothed, acute at apex (sometimes acuminate in ovate-leaved forms), green beneath, (0.5)-1.5-3-(4) × 0.5-1-(2) cm. Inflorescences few- to manyflowered, (5)—10-15—(20) cm long; peduncle slender to stout, usually glabrous, (2)—5—(10) cm, rachis and pedicels uniformly eglandular-hairy, sometimes glandular-hairy as well. Bracts and calyx ciliolate, sometimes glandular or glabrous. Corolla with magenta ring at throat, anterior lobe <2 mm wide. Capsule light to dark brown, (2.5)-3-(3.5) × 3-4 mm.

Stems brown (sometimes drying black), erect, bifariously hairy, 10-30-(45) cm tall. Leaves linear to narrow-lanceolate, widest between petiole and middle, usually shallowly toothed, acuminate at apex, green beneath, (3)-4-7-(10) × 0.3-1-(1.2) cm. Inflorescences many-flowered, (5)—10—15—(20) cm long; peduncle stout, glabrous or with eglandular hairs, 3-7 cm long, rachis and pedicels uniformly eglandular-hairy, very rarely glandular as well. Bracts and calyx ciliolate or rarely glabrous. Corolla with magenta ring at throat, anterior lobe >2 mm wide. Capsule light to dark brown, (2.5)-3-3.5 × 2.5-3 mm.

Leaf hairs sparse or scattered or absent, along midrib above, uniseriate eglandular and glandular with short 1-celled stalk and small vertically divided head. Apex acute or subacute or acuminate. Base cuneate or subcordate or cordate. Margin glabrous, serrate. Marginal teeth or lobes in (1–)2–10(–15) pairs. Petiole 1–4(–6) mm long. Inflorescence racemose, unbranched, (3–)10– 20(–35) cm long at fruiting, with (4–)10–25(–30) flowers. Indumentum of peduncle, rachis, and pedicels absent to very dense. Eglandular hairs of inflorescence erecto-patent or patent or antrorse, white or colourless or rust brown. Peduncle (1.5–)4– 7(–12) cm long, glabrous or eglandular-pubescent or eglandular-puberulent (rarely). Rachis (1.5–)6– 14 cm long, glabrous (rarely) or eglandular-pubescent or glandular-pubescent (in a few localities: Coromandel, Waikato, Tongariro National Park; Puketoi Ra.; Tararua, Rimutaka, Aorangi Ranges (alpine)), hairs in 1 row above each bract or all around rachis. Bracts alternate (spiralled), obtuse (rarely) or subacute or acute or acuminate, eglandular-hairy abaxially (rarely) or glandular ciliate (rarely) or eglandular ciliate or glabrous (rarely), linear or lanceolate or elliptic or ovate or narrowly deltoid. Bract margins entire. Pedicels erecto-patent at anthesis, straight at fruiting or incurved at fruiting, 5–15(–25) mm long, rarely glabrous or eglandular-pubescent or glandular-pubescent (rarely); hairs all around pedicel. Flowers: Calyx 4- lobed, (2–)2.5–3(–4) mm long. Calyx lobes linear or lanceolate or elliptic or ovate or obovate or oblong, acuminate to obtuse. Calyx hairs absent (calyx glabrous) or on margins only or on abaxial surface, eglandular or glandular or mixed eglandular and glandular. Calyx lobe margins entire. Corolla white at anthesis. Nectar guides evident, present on posterior and lateral corolla lobes. Colour ring and nectar guides magenta. Corolla throat yellow. Corolla 8– 12(–15) mm diam. Corolla tube (0.5–)1–1.5 mm long, 1 mm wide, hairy inside, hairs short or hairs papillate. Corolla lobes glabrous. Posterior corolla lobe circular or elliptic (rarely), obtuse or emarginate (sometimes) or divided in two (rarely), (4–)5–6(–7) × (2–)4–6(–6.5) mm. Lateral corolla lobes circular or oblong (broadly), obtuse, longitudinally folded around stamens, (4–)5–6(–8) × (2–)6–7(–7.5) mm.
