Sterile lamina up to 9-30 × 1.3-2.7 cm, narrowly elliptic to narrowly oblanceolate in outline, apex rounded to pointed, base wedge-shaped to tapering, slightly oblique, thinly set on the upper surface and densely set on the undersurface with pale brown to reddish-brown, translucent, oblong-lanceolate to round, ciliate scales, becoming glabrous with age.
