Polypodium chrysotrichum C. Christensen, Contr. U.S. Natl. Herb. 26: 320. 1931; Crypsinus chrysotrichus (C. Christensen) Tagawa; Phymatodes chrysotricha (C. Christensen) Ching; Phymatopsis chrysotricha (C. Christensen) Ching; Phymatopteris chrysotricha (C. Christensen) Pichi Sermolli.

Rhizome with whitish bloom, sparsely scaly; scales brown, ovate at peltate base, margin entire, apex acuminate. Fronds ± monomorphic (fertile fronds slightly narrower and more oblong). Stipe straw-colored, 5-10 cm, glabrous; lamina simple, ovate to oblong, 5-10 × 3-6 cm, base rounded to shallowly cordate, margin entire, wide, flat, translucent, apex caudate. Veins all distinct on both surfaces. Lamina leathery, both surfaces glabrous, abaxial surface pale green, adaxial surface green and shiny. Sori orbicular, medial.

Epiphytic on tree trunks; 2200-2900 m. Yunnan [Myanmar].

Hovenkamp believes that the broad, translucent margin described for Selliguea chrysotricha suggests that it might prove to be better placed within Arthromeris.
