Description |
Rhizome short-creeping, not branched, with dense white glandular indumentum amongst scale and rhizoid bases; rhizome scales narrowly to linear-lanceolate in outline, with white glandular hairs ± 0.1 mm long on adaxial surface. Stipe ± 1 mm apart in each row, 4.2–5.8 cm long, with simple eglandular hairs 0.2–2.4 mm long and simple glandular hairs ± 0.1 mm long, sometimes with white exudate. Lamina narrowly lanceolate in outline, 5.6–10.4 x 1.2–2 cm, apex rounded, base broadly wedge-shaped, deeply pinnately divided to a distance 0.7–1.3 mm from the midrib; pinnae 13–15 pairs and 2–5 pairs of apical lobes, lowest pairs of pinnae not reduced to auricles, more than 1/2 as long as longest pinnae, longest pinnae narrowly triangular, 0.4–1.4 x 0.3–0.8 cm, apex rounded to pointed; with simple eglandular hairs 0.3–2 mm long on abaxial surface of rhachis and on margin; lateral veins free. Sori with white gland exudate evident when young, throughout lamina, 6 in each row on longest pinnae, in apical 2/3 of pinnae to ± throughout, much nearer to margin than pinna mid-vein. |
