Perennial. Rhizomes present, short. Culms geniculately ascending or decumbent
or sprawling, 20–60(–200) cm tall, wiry, 4–10 -noded. Mid-culm internodes
glabrous or hirsute. Mid-culm nodes glabrous or pubescent. Leaf-sheaths glabrous
on surface. Ligule a fringe of hairs, 0.5–1 mm long. Leaf-blades linear or
lanceolate, flat, 3–20 cm long, 2–15 mm wide. Leaf-blade surface smooth or

Notes. Similar to E. minutifolia  by having flat leaf blades, as opposed to E. stricta and E. whiteana with incurved to involute leaf blades. Differs from E. minutifolia  by having leaf blades more than 3 cm long and soft in texture
