Grammitis nanodes (A.Peter) Ching

Rhizome short-creeping, sometimes branched, sometimes reproducing vegetatively by stolons ( Faden 69/846); rhizome scales lanceolate to narrowly lanceolate in outline, pale to medium red-brown or medium yellow-brown, glabrous. Fronds simple, very closely spaced; stipes 0.1–1 mm apart in each row. Stipe 1–16 mm long, with translucent to pale red-brown simple hairs ± 0.1 mm long. Lamina narrowly oblanceolate to linear-oblanceolate in outline, 1.4–6.5 x 0.2–0.5 cm, apex bluntly pointed to roundedd, base long-attenuate; hairless or with translucent to pale red-brown hairs on both surfaces of lamina and mid-vein and on margin; lateral veins 1-forked, each branch ending marked by a round to elongate hydathode on upper surface of lamina, free. Sori in apical 1/4 to 2/3 of lamina, 1–19 in each row.

From F.T.E.A., Paris (2005): "The descriptions and illustrations of G. nanodes in Schelpe (1970), Jacobsen (1983) and Burrows (1990) are referable to G. cryptophlebia". The name G. nanodes (Peter) Ching is put as a synonym under G. pygmaea (Kuhn) Copel.
