Conservation status of New Zealand indigenous vascular plants, 2012
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2012 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2009 and replaces all previous NZTCS lists for vascular plants. Authors: Peter J. de Lange, Jeremy R. Rolfe, Paul D.

Distribution

Endemic. New Zealand: South Island (north–west Nelson)

Habitat

Dracophyllum pubescens is a species of montane to subalpine areas where it grows in subalpine shrubland, on exposed cliff faces and bluffs, or in herbfield, fellfield or grassland.

Features

Multi–stemmed shrub 0.5–0.8 m tall. Branches decumbent to prostrate. Bark on old branches grey to dark grey, deeply fissured, young stems reddish brown. Leaves juvenile and adult, glaucous. Juvenile leaves spirally arranged along branches, spreading; lamina sheath 10–13 × 6–8 mm; shoulders rounded with margin ciliate in upper half; lamina 60–80 × 5–7 mm, linear–triangular to lanceolate, surfaces pubescent; margins serrulate with 60–70 obscured teeth per 10 mm. Adult leaves crowded at tips of branches, spreading, glaucous; lamina sheath 3.3–7.0 × 3.5–6.0 mm, striate, shoulders rounded to truncate and margins membranous, ciliate; lamina 14–65 × 2–6 mm, linear–triangular to lanceolate, adaxial surface densely pubescent to tomentose; abaxial surface sparsely pubescent; prominently striated; margins ciliate with 80–100 obscure teeth per 10 mm. Inflorescence a terminal spike on lateral branchlets; shorter than leaves, erect, lax, 15–17 mm long, oblong; inflorescence bract over-topping flowers, 7.4–21.8 × 1.6–2.5 mm, glaucous, ovate–lanceolate at base, pubescent, margin ciliate. Flowers 3–5, sessile; flower bract shorter than or equaling flower length, 9.5–13.0 × 1.0–2.5 mm, ovate–lanceolate, adaxial surface pubescent; abaxial surface with sparse scabrid hairs; margin ciliate. Sepals 5.0–5.5 × 1.3–2.0 mm, ovate–lanceolate to ovate, shorter than corolla tube, surfaces glabrous on the top half, pubescent on adaxial surface; margin ciliate. Corolla white; corolla tube 5.0–6.0 × 1.6–2.0 mm, cylindrical; corolla lobes spreading horizontally to reflexed, 1.5–2.0 × 1.5–2.0 mm long, triangular,shorter than corolla tube, apices inflexed, acute; adaxial surface papillate. Stamens inserted on corolla tube in the upper third, filament 0.5–0.8 mm long; anthers included, 0.8–1.0 mm, rectangular, light yellow. Ovary oblong, 1.4–1.5 mm long and wide, glabrous, apex truncate; nectary scales separate, 0.8–1.0 × 0.7–1.0 mm, rectangular, apices irregularly toothed; style included, glabrous, 1.5–2.0 mm long; stigma capitate. Fruit 1.5–2.0 × 1.5–2.0 mm, light brown, obovoid; apex truncate, glabrous. Seeds 0.7–1.0 mm long, brown, filiform, testa weakly and finely reticulate.

Similar Taxa

Dracophyllum pubescens is recognised by the grey, broadly fissured bark, dimorphic foliage (i.e. with distinct juvenile and adult foliage); by the glaucous, broad, pubescent leaves and by the few–flowered 1–4 racemes. The sepals of D. pubescens are 5.0–5.5 mm long, abaxially pubescent, while the corolla tube is 5–6 mm long. Of the other Dracophyllum species it is most similar to D. kirkii from which it differs by the distinctively pubescent leaves, and 3–5-flowered racemes (the flowers of D. kirkii are by contrast always solitary).

Flowering
