Notogrammitis gunnii (Parris) Parris

Rhizomes long-creeping, bearing scales. Rhizome scales ovate, 1.0–4.3 mm long, 0.5–1.2 mm wide, pale brown, concolorous, non-clathrate. Stipes distinct, or indistinct and winged almost to base, glabrous or hairy. Stipe hairs sparse, white to pale red-brown, 0.3–1.4 mm long. Fronds undivided, narrowly elliptic to narrowly obovate, 8–70 mm long or very rarely to 95 mm long, 2.5–7 mm wide, or very rarely to 8 mm wide; apices acute to obtuse; margins entire; bases attenuate to a distinct stipe or to a winged stipe; both surfaces pale green; herbaceous to coriaceous; bearing very sparse, pale brown hairs up to 1.0 mm long on the margin, costa or lamina surface. Hairs either setae, or branched hairs with setiform branches. Hydathodes absent. Sori globose to elliptic, elongated along veins, 1.5–4 mm long, in 1–7 pairs in mid to upper part of lamina, bearing white or pale brown hairs up to 1.5 mm long. Sporangia 220–320 µm long; spores 35–58 µm diameter.

Notogrammitis gunnii is a poorly known species but is characterised by long-creeping rhizomes, narrowly elliptic to narrowly obovate fronds, hairs on the stipe, and short, white or pale brown hairs in the sori. It is found in the alpine or subalpine zone, and distinguished from N. givenii by the presence of short hairs in the sori. It is less easily distinguished from N. patagonica but generally has a smaller frond (up to 95 mm long, cf. up to 160 mm long) and shorter, white or pale brown stipe and soral hairs.

Notogrammitis gunnii favours granite, marble, greywacke and schist outcrops, growing in soil amongst rocks and boulders, in rock crevices, and on cliff faces in subalpine and alpine habitats, often in tussock grassland.
