Descripción
Rhizomes short-creeping to ascending, stout, caudices 2–3 cm diam.; fronds 60–100 cm long; stipes stramineous to tan, ca. 1⁄5–2⁄5 the frond length, to 15–45 cm X 4–6 mm, along their whole length with rather dense hair-like scales, scales reddish brown, 4–10 X 0.2–0.3 mm, entire, saccate basally; blades dark green, pinnate-pinnatifid, broadly ovate, 40–60 X 23–35 cm; rachises abaxially with spreading hair-like scales like those of stipes, but shorter and less numerous; pinnae to ca. 15 pairs, sessile or proximal ones stalked to 3 mm, 12–20 X 2–4 cm, incised 1⁄3–2⁄3 their width, proximal pinna segments somewhat reduced; segments entire, 6–7 mm wide, rounded to acute at tips, margins ciliate with jointed hairs 0.1–0.2 mm long; veins simple, 7–12 pairs per segment, proximal 1 or usually 2(–3) pairs from adjacent segments running to sinuses; indument on costae abaxially of reddish brown, spreading, hair-like scales 2–3 mm long, also with a few glands less than 0.1 mm long; laminae between veins glabrous on both sides, or with scattered appressed, yellowish glands 0.1 mm abaxially; sori medial, exindusiate.

Discusión taxonómica
This is similar to C. microchlaena, but differs in the longer, broader, less incised pinnae, stipes more densely scaly along their whole length, rachises and costae abaxially with rather dense reddish brown, stiff, hair-like scales, broader segments 6–7 mm wide, basalmost 1–2(–3) pairs of veins from adjacent segments running to the sinus, and exindusiate sori.A
