 Description

Rhizomes short-creeping, bearing scales. Rhizome scales ovate to narrowly ovate, 2.8–7.1 mm long, 0.5–1.0 mm wide, pale brown, concolorous, non-clathrate. Stipes indistinct, winged almost to base, hairy. Stipe hairs sparse, white to pale brown, 0.2–1.7 mm long. Fronds undivided, linear, 31–165 mm long, 3–6 mm wide; apices acute; margins entire; bases attenuate to an indistinct winged stipe; both surfaces pale green; herbaceous; glabrous or bearing sparse pale brown hairs up to 1.3 mm long on abaxial surfaces of margins and midrib. Hairs either setae, or branched hairs with setiform branches. Hydathodes absent. Sori elliptic, elongated along veins, ± parallel to mid-vein or slightly oblique, 2–5 mm long, in 2–44 pairs in mid to upper part of lamina; bearing stout, dark red-brown hairs, up to 0.7 mm long, in and around the soral region. Sporangia 150–210 µm long; spores 21–31 µm diameter.

 Recognition

Notogrammitis rawlingsii is a very distinctive species characterised by its short-creeping rhizome, lack of distinct stipes, linear fronds, and presence of stout, dark red-brown hairs in and around the soral region. It is largely confined to lowland kauri forest in the northern North Island. It is most similar to N. billardierei, but distinguished by the characteristic red-brown hairs in the soral region and upright habit.

 Distribution

North Island: Northland, Auckland.

Altitudinal range: 20–600 m.

Notogrammitis rawlingsii is a rare fern found only in lowland and montane areas of the North Island from Whakaangi (Parris 12819, to be deposited in AK, not mapped) and Puketi Forest to Coromandel Peninsula and Mt Pirongia, and on Great and Little Barrier Islands.

 Habitat

Notogrammitis rawlingsii is confined to kauri or occasionally podocarp or hard beech forest. It usually grows on roots amongst forest mosses, on rotting logs, or sometimes on the ground. It reaches 600 m on Mt Pirongia.

 Biostatus
Indigenous (Endemic)

Notogrammitis rawlingsii was given a conservation status of Naturally Uncommon by de Lange et al. (2018).
