| 개요 | Plants perennial, 31.5-45.9 cm long, with long and short rhizomes. Culms trigonous, longer than leaves, 21.5-34.1 cm long, smooth; remnants of old leaves fibrous. Leaves at base brown, scalelike; distal leaf sheaths glabrous, 5.3-8.8 cm long; distal leaf blades glabrous, 4.3-8.6 cm long, 1.3-3.2 mm wide. Bracts 2-5, shorter than inflorescence; proximal bract sheaths 7.4-17.3 mm long; proximal bract blades 4.6-8.1 cm long, 1.6- 2.3 mm wide. Inflorescences racemose, with 3-6 spikes, 7.4- 16.3 cm long. Terminal spike staminate, 0.8-1.8 cm long, 1.0- 1.9 mm wide, with peduncles 1.9-6.4 mm long; scales green, white at margin, narrowly obovate, 3.1-4.2 mm long, 0.7- 1.1 mm wide, awned. Lateral spikes 2-5, pistillate, shorter than bracts, lowest ones 1.5-2.1 cm long, 2.6-3.9 mm wide, with penduncles 0.6-5.6 mm long; scales green, white at margin, ovate, 2.3-3.8 mm long, 0.5-0.9 mm wide, awned. Perigynia fusiform, 2.5-3.0 mm long, 0.8-1.1 mm wide, glabrous, veined at adaxial and abaxial surfaces, beak 0.4- 0.7 mm, mouth slightly bidendate. Achenes ellipsoidal, excavated at faces, 1.4-1.8 mm long, 0.7-0.9 mm wide; style base annulate. (Figs. 1, 2). Korean name: Ju-reum-cheong-sa-cho (주름청사초). Distribution: China, Japan and Korea.
