Nephrodium brownii Desvaux, Mém. Soc. Linn. Paris 6: 252. 1827; Aspidium floccigerum Blume; Davallia multiflora Roxburgh; Nephrolepis floccigera (Blume) T. Moore; N. multiflora (Roxburgh) F. M. Jarrett ex C. V. Morton.

Rhizome erect, short, producing long, dark brown stolons; scales lanceolate to ovate-lanceolate, appressed, with rufous center and brown, densely fimbriate margin. Fronds dark green when dry, bearing scattered, linear scales along veins abaxially, with sparse, curved hairs and stellate scales adaxially; stipe grayish brown, 15-45 cm × 2-3 mm, grooved adaxially, with appressed, brown, lanceolate scales; lamina broadly lanceolate or elliptic-lanceolate, 30-70(-100) × 9-15 cm, pinnate; pinnae numerous (20-50 pairs), approximate, basal ones gradually shorter and more widely spaced, upper ones never so close as to touch each other, subsessile; middle pinnae lanceolate or linear-lanceolate, 4-8 × 1-1.3 cm, base unequal, triangularly auriculate on acroscopic side, margin obviously crenate, apex acuminate; rachis densely covered with brown, fibrous scales on upper side. Sori ca. 2 mm apart, submarginal, orbicular; indusia rufous, orbicular-reniform.

Forests; 200-1200 m. Fujian, Guangdong, Guangxi, Hainan, Taiwan, Yunnan [Cambodia, India, Indonesia, Japan (including Ryukyu Islands), Laos, Malaysia, Myanmar, Philippines, Singapore, Sri Lanka, Thailand, Vietnam; SW Asia, Australia, North and South America (introduced), Pacific islands].

This material was treated as Nephrolepis hirsutula (G. Forster) C. Presl in FRPS (6(1): 149. 1999). However, one of us (Hovenkamp) has examined the type and maintains that N. hirsutula is a Malay/Pacific species and does not occur in China.
