Flora Category

Vascular - Native


Drosera circinervia Colenso, D. stylosa Colenso, Drosera peltata subsp. auriculata ( Planch. ) B.J.Conn


Indigenous. North and South Islands to about south Canterbury, northern Otago and south Westland/ Present in Australia


Coastal to montane, on recently exposed and naturally open ground, clay pans, in low scrub, on lava. Often abundant following fire.


Tuberous herb. Plants usually olive-green in exposed locations, rarely richly maroon; tuber ovoid to globose, up to 10 × 8 mm; surface white to red, often in a papery sheath; vertical stolon 20–80 mm long. Stem erect, usually simple, sometimes shortly branched, 90–600 mm long, glabrous. Leaves often in a flat basal rosette and cauline; basal leaves 4–19, the lamina ovate, elliptic, orbicular or reniform, 1.8–3.5 × 2–6 mm wide on a linear petiole 5.0–17.0 × 1.2 mm wide; 9–36 cauline leaves alternate, the lamina crescentic, 1.5–5.5 × 2.0–5.5 mm, with acute angles, on petiole 3–23 mm long. Inflorescence a 1-sided raceme 2–14-flowered; peduncle usually 6–50 mm long, but up to 80 mm; pedicels 1–14 mm long. Sepals 2.0–6.0 × 0.9–2.6 mm, ovate, elliptic and rarely obovate, glabrous with an entire to irregularly serrulate margin. Petals 3.0–10.0 × 1.5–5 mm, white or pink, obovate, cuneate, apex emarginate, sometimes obtuse and rarely truncate. Styles 3, 0.6–1.4 mm long, divided into a total of c.15–30 cylindrical segments. Seeds 0.8–1.6 mm long, cylindrical with a shallowly reticulated surface.

Similar Taxa

Drosera auriculata could only be confused only with D. hookeri, with which it often grows in Northland and from which it differs by the glabrous rather than hairy sepals and cylindrical rather than ovoid to arachniform (i.e. peanut-shaped) shallowly reticulated seeds (rather than deeply pitted seeds) which are > 1 mm long, rather than 0.5-8.0 mm long. Sometimes the seeds of Drosera hookeri can be cylindrical, and so a little like those of D. auriculata, but in these cases they can be distinguished from D. auriculata by their smaller size and deeply pitted testa.
