| 개요 | Annuals dwarf, with fibrous roots. Rhizomes absent. Culms tufted and ribbed, ca. 5?15 cm tall, slightly upwardly scabrous at least at top including inflorescence. Leaves linear, with about half size of culms, 3.0?5.0 cm × 1.0?2.0 mm, distinctly curved or falcate to left or right direction, margins upwardly scabrous, apices acute or short acuminate; ligule absent. Inflorescences simple or subcompound, with about 3?10 spikelets, up to 4 cm long, upwardly scabrous; primary branches 3?5, obliquely erect, scabrous, up to 3 cm long; secondary branches very short; involucral bracts 2?5, much shorter than inflorescence, 0.5?2.0 cm × 0.8?1.0 mm, margins scabrous, apices acuminate. Spikelets solitary, lanceolate, strongly laterally compressed, ca. 6?12-flowered, apices acute, 3.0?7.0 × 1.5?2.0 mm, brown; scales distichously equitant, membranous, lanceolate to ovate, 2.2?3.0 × 1?1.5 mm, minutely scabrous at midnerves and margins, prominently midkeeled, apices mucronate. Stamens 2 or 3; anthers yellow, oblong, ca. 0.5 mm long. Ovaries white; styles 3 angled, basally inflated, glabrous, ca. 2 mm long; stigmas 3. Achenes obovate, dully 3-sided, nearly whitish, truncate at bases, 0.6?0.9 × 0.4?0.6 mm, smooth or verruculose, nearly sessile. Flowering: Aug.?Sep. Habitat: There are about 100 individuals in open and wet areas on mountain’s foot within plant community of Pinus thunbergii and Eurya japonica near the coastal lines. Distribution: N Australia, Bhutan, China (southern provinces including Guangdong and Zhejiang), India, Indonesia, Japan (Ryukyu Islands), Korea (southern island in province Jeollanam-do), Malaysia, Myanmar, Nepal, Papua New Guinea, Thailand, Vietnam (from Kern, 1974; Zhang et al., 2010). |
