Descriptions
Rhizome stout, ascending, clad in dark to pale brown linear-lanceolate, attenuate paleae up to 1 cm. long; stipites crowded, densely paleate at base. Stipes stiff, erect, pale green except towards darker base; ± paleate, becoming nude with age, 3-15 cm. long. Rhachis stout, sparingly paleate, with up to 12 alt. lateral pinnae and larger terminal pinna. Lamina irregularly ovate-oblong, 3-20 × 1·5-5 cm., subcoriac., greyish green, ± paleate below. Pinnae stalked, about ovate-oblong to broad-oblong, 15-35 × 2-15 mm., crenulate; lower pinnae often lobed towards base, or with a single pinnule up to 1 cm. long; veins obscure to distinct, simple or forked from near base. Terminal pinna up to 4 cm. × 15 mm., ovate, obtuse. Sori us. cop., oblong, 3-4 mm. long, sts confluent and covering most of surface; indusium firm, pale.
Asplenium lyallii (Hook.f.) T.Moore
Rhizome stout, ascending, bearing brown subulate to narrowly triangular scales up to 25 × 2 mm. Stipes 3-20 cm long, pale brown at base and on underside, green elsewhere, covered with scales similar to but smaller than those of the rhizome (Fig. 4F-L). Laminae lanceolate to elliptic, 4—40 × 2—20 cm, dark shiny green to dull grey-green, pinnate to bipinnate. Raches normally green, occasionally brown on the underside, often grooved, scaly. Pinnae 2-16 pairs, ovate to narrowly oblong, obtuse to acuminate, serrate to ± entire, stalked, 1-10 × 0.5-5 cm, often covered on both surfaces with tiny scales. Lowermost pinnae normally at least partially lobed or divided at the base, sometimes completely pinnate; pinnules stalked, lanceolate to elliptic, obtuse, serrate to entire, up to 3 × 1.5 cm. Sori up to 10 mm long, not reaching lamina edge. Spores (36)40-54(60) mcm long, (23)27-35(40) mcm wide (13 populations), perispore prominently winged and ridged (Fig. 29K-L).
