Basionym: Lunathyrium emeiense Z. R. Wang, Fl. Reipubl. Popularis Sin. 3(2): 510. 1999.

Fronds caespitose; fertile fronds ca. 90 cm; stipe ca. 20 cm, ca. 4 mm in diam., subglabrous; lamina pinnate-pinnatipartite, narrowly oblong-lanceolate, ca. 58 × 18 cm, base gradually narrowed, apex acuminate; pinnae ca. 20 pairs, middle pinnae alternate, ascending, linear-lanceolate, ca. 10.5 × 1.8-2 cm, base broader and subtruncate, subequilateral, pinnatipartite, apex long acuminate; lower 5 or 6 pairs of pinnae gradually shortened toward base; basal pinnae spreading, lanceolate, ca. 2 × 1 cm, acroscopic base broader, ca. 5 cm apart from second basal pinnae, upper pinnae gradually closer; pinna segments ca. 15 pairs, ascending, separated by narrow space, oblong, adnate to narrow wing, apex and distal margin serrulate, apex obtuse-rounded. Veins visible on both surfaces, pinnate in segments, 6 or 7 pairs, simple, occasionally forked, oblique. Lamina herbaceous when dried, greenish brown, rachis, costae, and veins abaxially occasionally with short multicellular hairs or subglabrate. Sori oblong to shortly linear, 1-2 mm, medial, 2-4 pairs per segment; indusia similar to sori, brown, slightly erose at margin. Spores bilateral, perispore surface with dense baculate or thin long rugate processes.

● Shrub groves on mountain slopes, damp areas; 2000-2100 m. Sichuan (Emei Shan).

Deparia emeiensis is very similar to D. wilsonii; however, the segments are prominently toothed at the margin, and the spore surface has dense baculate or thin long rugate processes.
