This is a tall species with a large panicle, only likely to be confused with Melica onoei, from which it can be distinguished by its narrower, thinner leaf blades, longer ligules, and spikelets with more florets, in addition to the key characters. It is a species of the W Himalayas. Specimens reported from China have not been seen.

Rhizomatous perennial; culms 50-150(-185) cm high, erect or ascending. Leaf blades linear, 15-35 cm long, 3-5.5 mm wide, flat or convolute when dry, scaberulous; ligule truncate, 1-2 mm long; sheaths, or at least the lower retrorsely scabrid or hispid. Panicle 20-40 cm long-, lax, the branches distant, 6-15 cm long, ascending, spreading or deflexed, bearing spikelets on filiform pedicels 2-6 mm long. Spikelets oblong, 8.5-13 mm long, with 2-3 fertile florets scarcely distinguished from the sterile and separated by internodes 2-2.5 mm long; glumes elliptic or lanceolate, acute, broadly membranous, the lower 3.5-4.5 mm long, the upper 4.8-6.3 mm long, lemma of fertile floret elliptic-oblong, 7-8.5 mm long, acute or subacute with narrowly membranous tip, strongly 7-9-nerved, scaberulous.

Perennial. Culms 90–200 cm tall, 2–3 mm in diam., many-noded. Leaves all cauline, leaf sheaths as long as or longer than internodes, harshly retrorsely scabrid on veins, teeth sometimes elongated into short bristles; leaf blades thin, 15–25 cm × 3–7 mm, abaxial surface scabrid, adaxial surface smooth, glabrous or sparsely hispid; ligule 1–2.3 mm. Panicle open, 15–30 cm; branches 2 or 3 per node, distant, eventually divaricate, usually branched, up to 15 cm, spikelets often clustered on the branchlets. Spikelets narrowly elliptic, 10–14 mm, green, fertile florets 2 or 3, 1 or 2 similar but smaller sterile florets raised on elongate internodes; glumes unequal, clearly shorter than adjacent florets, lower glume narrowly ovate, 2.6–5.2 mm, upper glume lanceolate, 3.8–6.5 mm, both acute; lemmas narrowly lanceolate, lowest 6–9 mm, granular-scaberulous, 5–7-veined, upper margins and apex membranous, apex subacute; palea keels scabrid-ciliolate. Anthers ca. 2 mm. Fl. Jul–Aug.

provided by wikipedia EN
Melica scaberrima, is a species of grass that can be found in Yunnan, China, Nepal,[1] Pakistan and northern part of India (including Kashmir).[2]
Description
The species is perennial and have elongated rhizomes. It culms are erect and are 50–150 centimetres (20–59 in) long. The species leaf-sheaths are tubular and scabrous with one of their length being closed. It eciliate membrane is 1–2 millimetres (0.039–0.079 in) long and have a glabrous surface. They also have flat leaf-blades which are 15–35 centimetres (5.9–13.8 in) long by 3–5.5 millimetres (0.12–0.22 in) wide and have scaberulous surface.[3]
The panicle itself is open and is 20–40 centimetres (7.9–15.7 in) long. The branches are distant and are 6–15 centimetres (2.4–5.9 in) long. The spikelets are oblong, solitary and are made out of 2–3 fertile florets that are 8.5–13 millimetres (0.33–0.51 in) long. Fertile spikelets are pediceled, the pedicels of which are filiform and are 2–6 millimetres (0.079–0.236 in) long. Florets are diminished at the apex.[3]
Its lemma have scabrous surface and acute apex with fertile lemma is being chartaceous, elliptic, keelless, and is 7–8.5 millimetres (0.28–0.33 in) long. Both the lower and upper glumes are elliptic, keelless, membranous, and have acute apexes. Their size is different; Lower glume is 3.5–4.5 millimetres (0.14–0.18 in) long while the upper one is 4.8–6.3 millimetres (0.19–0.25 in) long. Palea is 2-veined. Flowers are fleshy, oblong, truncate, have 2 lodicules, and grow together. They have 3 anthers which have fruits that are caryopsis and have an additional pericarp with linear hilum.[3]
Ecology
It is found on forest edges, slopes, and grass at 2,800–4,000 metres (9,200–13,100 ft) above sea level. It blooms from July to August.[1]
