Eulalia sect. Pseudopogonatherum (A. Camus) Pilger; Puliculum Stapf ex Haines.
Annual. Culms solitary or tufted, slender, glabrous. Leaf blades narrowly linear, often inrolled; ligule a narrow membranous rim, margin densely ciliate. Inflorescence terminal, composed of several to many subdigitate racemes in a dense brushlike cluster; racemes tough or fragile, spikelets of a pair similar, usually both pedicelled on unequal pedicels (one sessile and the other pedicelled in P. koretrostachys), both fertile; rachis internodes and pedicels linear, hairy along angles. Spikelets lanceolate or lanceolate-oblong; callus obtuse to acuminate, shortly bearded; glumes membranous or papery; lower glume slightly convex, flanks rounded, 2-keeled upward, back usually hairy, veinless between keels, keels ciliate toward apex, apex truncate or bidentate; upper glume boat-shaped, apex mucronate or awned; lower floret reduced to an oblong hyaline lemma or absent; upper lemma stipelike, entire or 2-toothed, awned; awn well developed, geniculate, column dark brown, hairy, limb pallid; palea usually absent. Stamens 1–3.
Three to five species: NE India and Myanmar through SE Asia to the Philippines, Australia, and the Pacific Islands; three species (one endemic) in China.
This genus has been included in Eulalia, but is distinguished by its delicate, annual habit, pedicelled spikelets on tough or only tardily fracturing racemes, and very narrow intercostal long cells in the leaf epidermis.
Pseudopogonatherum irritans (R. Brown) A. Camus is likely to occur in SE China. It is found from Myanmar, Thailand, Vietnam, and the Philippines through Indonesia to Australia.
