类芦属 lei lu shu

Authors: Shou-liang Chen & Sylvia M. Phillips

Perennials, stout. Culms tall, reedlike, solid. Leaf blades cauline, linear, flat, finally deciduous from sheaths; ligule a line of long hairs. Inflorescence a large plumose panicle, primary branches in clusters or solitary on central axis. Spikelets laterally compressed, florets several, all bisexual or lowest sterile and without a palea; rachilla glabrous, disarticulating above glumes and sterile floret (when present) and between fertile florets; glumes lanceolate, shorter than lemmas, subequal or unequal, scarious-membranous, 1–3-veined, obtuse to acuminate or aristulate; lemmas ovate-lanceolate, scarious-membranous, 3-veined, long-ciliate on lateral veins, keeled, apex setaceously bidentate with a short, often recurved awn from the sinus; palea shorter than lemma, hyaline, keels very shortly ciliate. Callus oblong, bearded. Caryopsis narrow, subterete.

Five species: Old World tropics; four species (two endemic) in China.

Although Neyraudia has slender, arundinoid microhairs, its other features, including the embryo, are typically eragrostoid.
