Some forms of Nephrolepis biserrata closely resemble N . multiflora in pinna shape and indument but lack the distinctively transparent-margined (i.e., bicolored) and persistent petiole scales of the latter species. Nephrolepis multiflora also has more appressed and darker-colored stem scales.

Rhizome short, erect, with long stolons, not producing tubers.
Fronds tufted, suberect to arching, up to 4 m long.
Stipe up to 75 cm long, light brown, shiny, with narrowly lanceolate, light brown scales at the base, glabrous with age.
Lamina up to 3.25 × 0.5 m, narrowly elliptic to linear oblong-lanceolate in outline, pinnate, lower pinnae slightly reduced.

provided by wikipedia EN
Nephrolepis biserrata (giant swordfern, 长叶肾蕨) is a tropical fern, endemic to Florida, Mexico, the West Indies, Central America, South America, Africa, and southeast Asia.
Its stipes are grayish brown and 10–50 cm × about 4 mm in size, with brownish-green, papery lamina that are 14–30 cm wide × 0.7–2 m in length, but has occasionally attained a length of twenty-seven feet (eight meters).[1] This is the largest of all the sword ferns and it often is labeled, Macho Fern, at nurseries.[2] after its aggressive growth nature when compared to ferns such as the Boston Sword Fern, Nephrolepis exaltata that is planted more commonly.
