The plant is known as Adiantum capillus-veneris, also called fingerleaf maidenhair fern in "Flora of China." The plant grows 20-40 cm tall. The rhizome is short and creeping, about 3 mm thick, with scales at the tip; the scales are narrow and linear, about 2 mm long, dark brown, shiny, entire, with slightly twisted tips. Leaves are numerous and clustered; sterile and fertile leaves are equal in length. The petiole is slender, 15-30 cm long, about 1 mm thick, straw-colored, brown at the base, slightly shiny, smooth or occasionally rough. The blade is finger-like, usually with 5–7 pinnae, sometimes 3, occasionally with a nearly trifurcated basal pair or apical pinna bifurcated 2–3 times, all arising from the top of the petiole. The central pinna is longer, narrowly linear, 8–10 (15) cm long, (2) 3–4 (8) mm wide, gradually tapering to a point, wedge-shaped at the base, not decurrent. Lateral pinnae are similar but slightly falcate, sessile or only the terminal pinna has a short stalk. Fertile pinnae are nearly entire, with fine serrations only at the apex; sterile pinnae have fine sharp teeth along the margin. The midrib is straw-colored, smooth, deeply grooved above, raised below; lateral veins are distinct, sparse, straight, parallel, slightly oblique, simple or occasionally forked from the lower part. When dry, the leaf texture is firm and herbaceous, gray-green, smooth on both sides. The sori are linear, extending along the margin, absent only at the apex; the indusia are linear, gray-white, membranous, nearly entire.
