Inflorescence a large open panicle, the ultimate spikes with a very fine and almost capillary but not zigzag axis, branches thinly patent-pilose below, glabrous above, brownish. Tepals green: outer 2 c. 3.75–4 x 1.5–1.75 mm, cucullate, glabrous, the 3 strong nerves meeting at the apex; inner 2 slightly shorter, with a strong central nerve and 2 fine laterals, with a broadly hyaline margin at least as wide as the green centre, the margin slightly constricted below the apex; middle tepal with one side as for the outer, the other as for the inner tepals.
