Matteuccia intermedia C. Christensen, Bot. Gaz. 56: 337. 1913; Onoclea intermedia (C. Christensen) M. Kato, T. Suzuki & Nakato.
Rhizome short and robust, erect, dark brown, apical part densely covered with dark brown scales; scales broadly lanceolate, ca. 1.5 cm × 4 mm, membranous, entire, apex acuminate. Fronds tufted. Stipe of sterile frond brown, 20-30 × ca. 0.5 cm, base dark brown, firm, bearing prominent pneumatophores, with sparse lanceolate scales; sterile lamina bipinnatifid, elliptic, 40-60 × 15-25 cm, slightly narrowed downward, papery, glabrous, with brown linear-lanceolate scales on rachis; pinnae 20-25 pairs, alternate, oblique, close, midveins ca. 1.5 cm apart, basal 2 or 3 pairs of pinnae shortened, slightly reflexed; middle pinnae largest, linear or oblong-lanceolate, 13-15 × 1.5-2 cm, base truncate, sessile, margin pinnatifid, apex acuminate; lobes 20-30 pairs, close, oblong, entire, apex rounded or truncate with points; veins obvious, pinnate, veinlets simple or sometimes furcate, reaching lamina margin. Stipe of fertile frond 20-25 × 0.5-0.8 cm; fertile lamina shorter than sterile lamina, pinnate, elliptic, 30-45 × 8-15 cm; pinnae close, dark purple, linear, 3.5-5.5 × 0.2-0.3 cm.
