The plant is called Adiantum capillus-veneris, also known as Adiantum raddianum in "Flora of China". The plant grows to a height of 20-40 centimeters. Its rhizome is short and creeping, about 3 millimeters thick, with scales at the tip. The scales are linear, about 2 millimeters long, black-brown, shiny, entire, and slightly twisted at the upper part. The plant has numerous leaves, clustered together, with sterile and fertile leaves of equal length. The leaf stalk is slender, 15-30 centimeters long, about 1 millimeter thick, straw-colored, brown at the base, slightly shiny, smooth, or occasionally rough. The leaf blade is finger-shaped, usually consisting of 5-7 pinnules, sometimes 3 pinnules, occasionally with a pair of nearly trifurcate or apical pinnules at the base, all arising from the tip of the leaf stalk. The central pinnule is longer, linear, 8-10 (15) centimeters long, (2) 3-4 (8) millimeters wide, gradually tapering at the tip, wedge-shaped at the base, without downward extension. The lateral pinnules are similar in shape but slightly sickle-shaped, all sessile or with short stalks only on the apical pinnules. Fertile pinnules are nearly entire, with fine serrations only at the top, while sterile pinnules have fine sharp serrations along the edges. The main vein is straw-colored, smooth, deeply grooved on the upper surface, and raised on the lower surface. The lateral veins are distinct, sparse, nearly straight, parallel, slightly oblique, single or occasionally bifurcated from the lower part. When dried, the leaves become tough and grassy, gray-green, and smooth on both sides. Sporangia are linear, extending along the leaf margin, present only at the top of the pinnules; the sporangial cover is linear, gray-white, membranous, with nearly entire margins. The growth environment is...
