New Zealand material, comprising one known collection, has the following characteristics. Rhizomes erect, bearing orange-brown hairs. Fronds c. 380 mm long, hemidimorphic. Stipes c. 210 mm long, bearing orange-brown hairs. Sterile portion of each lamina pinnate, ovate, c. 170 mm long, c. 130 mm wide. Primary pinnae in 2–5 pairs below a similar apical pinna, ovate, apices acuminate, the longest c. 80 mm long, 20 mm wide. Rachises bearing orange-brown hairs. Venation reticulate. Basal pair of pinnae fertile, held erect on stalks c. 100 mm long, arising very close to basal pair of sterile pinnae; apical portion skeletonised, 3–4 pinnate, c. 70 mm long, c. 15 mm wide, bearing sporangia in two rows either side of each costa.


North Island: Northland
