Description

Rhizomatous perennial; culms 20-60 cm high, slender, erect or ascending. Leaf-blades linear-lanceolate, 4-20 cm long, 2-6 mm wide, flat, puberulous above; ligule truncate, 0.2-03 mm long; sheaths scaberulous, the lower purplish.

Description

Perennial, with slender creeping rhizomes. Culms scattered, 25–970 cm tall, 1–2 mm in diam. Leaf sheaths keeled, very narrowly winged, wing margin and sometimes veins scabrid, glabrous or sparsely pubescent at junction with blade, lower sheaths purplish; leaf blades flat, thin, 10–26 cm × 2–5 mm, abaxial surface smooth, adaxial surface puberulent, sometimes sparsely pilose, transverse veinlets present; ligule ca. 0.3 mm or almost absent. Panicle lax, 4–15 cm, racemelike, 1-sided, eventually nodding; spikelets 5–15, mostly borne in pairs or singly directly on main axis, lowest branch sometimes bearing 2 or 3 spikelets. Spikelets obovate, 5–8 mm, glumes purple, florets green, fertile florets 2(or 3), terminal sterile lemmas gathered into globular cluster; glumes broadly ovate, subequal, 4–6 mm, margins broadly membranous, 3–7-veined, both obtuse; lemmas broadly elliptic, lowest 5–7 mm, leathery, 7–9-veined, additional intermediate veins in lower part, scaberulous or puberulous, apex obtuse; palea keels ciliolate.

Melica nutans

Melica nutans is a grass species in the Poaceae family, native to European, Eurasian, and Asian forests.[1]

Description[edit]

The grass has slender creeping rhizomes. The culms are 25–970 centimetres (9.8–380 in) tall.[1] It inflorescence is comprised out of 5–15 fertile spikelets, which are both oblong and compressed, with the length of 6–8 millimetres (0.24–0.31 in). They are comprise out of 2-3 fertile florets that are diminished at the apex. The florets are 5–7 millimetres (0.20–0.28 in) long and are elliptic. Flowers have 3 anthers which are 1.5–2 millimetres (0.059–0.079 in) in length. Glumes are thinner than fertile lemma with the lower one being of 4–6 millimetres (0.16–0.24 in) which is one length of upper one.[2]

Habitat[edit]

It is found at 1,500–2,300 metres (4,900–7,500 ft) of elevation, in shady and hillside habitats.[1]
