This species is mainly distributed from Japan to Yunnan, but a few gatherings are known from the W Himalayas. The combination of broad leaf blades, short ligule, narrow, green spikelets and smooth palea keels distinguishes it from other Chinese
Melica species with a large, open panicle.
Melica onoei var. pilosula Papp (Acad. Romana, Mem. Sect. Sti., ser. 3, 12: 242. 1937) was described as having a simple, contracted panicle, smooth leaf sheaths, a long pilose adaxial leaf surface, and a pointed, ca. 5 mm ligule. The panicle and ligule definitely exclude it from M. onoei. It is based on a specimen from Beijing that has not been seen.

Melica onoei is very similar to Melica scaberrima, differing mainly by the smaller dimensions of the parts of the spikelet, the frequently narrower panicle and the broader leaves.

Rhizomatous perennial; culms 75-110 cm high, erect or ascending. Leaf-blades ± linear, 20-35 cm long, 3.5-11 mm wide, broadest in the middle, flat or convulute when dry, scaberulous and sometimes also loosely hispid; ligule truncate, 0.5-1 mm long; sheaths smooth and glabrous or thinly retrorsely hispid.

Melica onoei
provided by wikipedia EN
Melica onoei is a species of grass found in China, Japan, Korea,[1] Pakistan[2][3] and Taiwan.[4]
Description
The species is perennial and have elongated rhizomes. It culms are 75–110 centimetres (30–43 in) long. The species leaf-sheaths are tubular and smooth with one of their length being closed. It eciliate membrane is 0.5–1 millimetre (0.020–0.039 in) long and is truncate. They also have flat leaf-blades which are 20–35 millimetres (0.79–1.38 in) long by 3.5–11 millimetres (0.14–0.43 in) wide and have scaberulous and hispid surface. Both the leaf-sheaths and leaf-blades have glabrous surface.[5]
The panicle itself is open and is 30–35 centimetres (12–14 in) long with the main branches being distant from each other and are 7–12 centimetres (2.8–4.7 in) long. The spikelets themselves are solitary and oblong and are made out of 2 fertile florets that are 6.5–8 millimetres (0.26–0.31 in) long. Fertile spikelets are pediceled and have rhachilla stems that are 2 millimetres (0.079 in) long. Florets are diminished at the apex.[5]
Its lemma have scaberulous surface and emarginated apex with fertile lemma being chartaceous elliptic, keelless, and 4.5–5.5 millimetres (0.18–0.22 in) long. Both the lower and upper glumes are elliptic, keelless, membranous, and have acute apexes. Their size is different; Lower glume is 2.5–3.3 millimetres (0.098–0.130 in) long while the upper one is 4–5 millimetres (0.16–0.20 in) long. Palea is 2-veined. Flowers are fleshy, oblong, truncate, have 2 lodicules, and grow together.[5] They have 3 anthers which are 0.8–1.5 millimetres (0.031–0.059 in)[1] long with fruits that are caryopsis and have an additional pericarp with linear hilum.[5]
Ecology
It is found on hillsides, gullies, and roadsides on elevation of 400–2,500 metres (1,300–8,200 ft). It blooms from May to October.[1]
