Petiole 0.5–3(–4) mm long, hairy along margins and often hairy above and below. Inflorescences with (20–)30–130(–190) flowers, lateral, racemose and unbranched, (2–)6– 15(–20) cm long, longer than (mostly) or about equal to subtending leaves, flowers opening in acropetal sequence or synchronously within inflorescence, usually with all flowers (including those near the apex) developing to maturity or rarely with a number of unopened flowers toward the apex; peduncle (0.3–)1–2.8 cm long, eglandular pubescent; rachis (1.7–)4–12(–17.5) cm long, eglandular-pubescent; bracts alternate, acute or subacute, ciliate with both glandular and eglandular hairs and sometimes eglandular-hairy outside and/or inside, narrowly deltoid or lanceolate; pedicels much longer than (usually) or equal to or shorter than bracts, eglandular-pubescent, erecto-patent or patent to slightly recurved at anthesis, erecto-patent or ascending or recurved at fruiting. Flowers on individual plants either hermaphrodite or female (the commonness of male sterility is not known, only a few possibly male-sterile specimens are known). Calyx (1.7–)2.3–4 mm long, 4-lobed, equally divided; lobes all similar, deltoid (sometimes narrowly) or lanceolate, acute or acuminate or subacute, with mixed glandular and eglandular cilia and sometimes hairy outside and/or hairy inside, margins narrowly membranous and sometimes tinged pink. Corolla lobes mauve at anthesis (at least faintly) and white after pollination, corolla tube always white; tube hairy inside and often hairy outside (especially near apex, toward clefts between lobes), (1.9–)2.5–5.5 mm long, 1.3–1.7(–1.9) mm wide, narrowly funnelform to shortly cylindric and contracted at base, c. equalling or longer than calyx; tube of female flowers 2–2.5 mm long; lobes longer than or equalling or shorter than corolla tube (the latter condition only true of the anterior lobe), usually hairy inside or at least with a few hairs toward base on inner surface and sometimes hairy outside; posterior lobe lanceolate or elliptic, subacute (mostly) or obtuse, suberect to patent, with margin and apex flat; lateral lobes lanceolate or elliptic, subacute or obtuse, suberect, with margin and apex flat; anterior lobe lanceolate, subacute to obtuse, suberect, with margin and apex flat. Stamen filaments white, diverging after anthesis, 4.5–6 mm long; anthers subacute to conspicuously apiculate, mauve or purple, 1.1–1.5 mm long; sterile anthers 0.8–1 mm long (when dry). Nectarial disc glabrous. Ovary ovoid, eglandular hairy or glabrous (may vary on one plant), 0.9–1.1 mm long; ovules c. 6– 11 per locule, marginal in one layer on a flattened placenta; style 3.5–7(–10.5) mm long, c. 0.15– 0.175 mm thick, with uni- and multi-cellular hairs or glabrous (can vary on one plant), white or mauve; stigma no wider than style, yellow or green or mauve or red at anthesis, c. 0.15–0.175 mm wide. Capsules latiseptate, obtuse or subacute, dark brown, 2.5–4(–5) mm long, 2–3.4 mm wide, with eglandular, unicellular hairs and with eglandular, multicellular hairs or glabrous, septicidal split extending to base, loculicidal split extending 1⁄4 – 1⁄2 way to base.

Shrub to 2 m tall, usually erect. Branchlets uniformly hairy, with hairs varying from relatively short to very long and woolly. Leaf bud sinus small, rounded to square or oblong, often filled with hairs. Leaves lanceolate, oblong, elliptic or linear, subcoriaceous to coriaceous, (15–)30–70(– 87) mm long, (3.5–)7–14(–18) mm wide; upper surface dark to yellow-green; underside of lamina usually covered with long eglandular hairs, rarely glabrous; underside of midrib hairy, with many hairs usually > 0.2 mm long; margins pubescent. Inflorescences (2–)6–13(–20) cm long. Outer surface of calyx lobes hairy. Corolla lobes at least faintly mauve when young, fading to white after anthesis, covered outside with eglandular hairs; corolla tubes (1.9–)2.4–3.9 mm long. Ovaries usually hairy (on any one plant at least some ovaries hairy), and usually with eglandular hairs scattered over entire surface.

Shrub with habit varying from low and spreading (e.g., c. 30 cm tall, 1 m wide) to erect (to c. 1.5 m tall), depending on situation. Branchlets uniformly and minutely puberulent, or glabrous. Leaf bud sinus small and rounded. Leaves lanceolate, narrowly elliptic, or linear-lanceolate, subcoriaceous to coriaceous, (25–)40–65 mm long, 7–15(–19) mm wide; upper surface dark to yellowgreen; underside of lamina glabrous; underside of midrib glabrous or hairy, hairs when present being < 0.2 mm long; margins pubescent to puberulent (at least toward base). Inflorescences 5.5–10 cm long. Outer surface of calyx lobes usually glabrous, but sometimes hairy. Corolla lobes at least faintly mauve when young, fading to white after anthesis, glabrous outside (but only a few flowering specimens available for examination); corolla tubes 2.7–3.9 mm long. Ovaries glabrous or sparsely hairy (especially along septal grooves).

Inflorescences 5.5–14.5 mm long. Outer surface of calyx lobes glabrous or hairy (always glabrous on plants from the Mokohinau Islands). Corolla lobes faint mauve to vivid purple-mauve when young, usually fading to white after anthesis, outer surface either glabrous (but with margins often ± ciliate near base) or hairy (always glabrous on plants from the Mokohinau Islands); corolla tube (2.5–)3–5.5 mm long. Ovaries usually sparsely hairy (especially along septal grooves), sometimes glabrous.
