    Glume
    Glumes persistent; reaching apex of florets. Lower glume lanceolate (1), or ovate (4); 0.5-0.581-0.75 length of upper glume; chartaceous; without keels; 3 -veined. Lower glume surface glabrous (4), or puberulous (1), or pubescent (3), or setose (4). Lower glume apex acute (4), or acuminate (1). Upper glume ovate; chartaceous; without keels; 3 -veined. Upper glume surface glabrous (4), or puberulous (1), or pubescent (3), or setose (4); with simple hairs (1), or tubercle-based hairs (4). Upper glume apex acute.
    Florets

Fertile lemma oblong; chartaceous; without keel; 5 -veined. Lemma surface glabrous (2), or pubescent (3), or pilose (1); with a transverse row of hair tufts. Lemma margins involute; interlocking with palea keels. Lemma apex lobed; 2 -fid; awned; 3 -awned. Principal lemma awn from a sinus; geniculate. Lateral lemma awns shorter than principal. Palea 2 -veined. Palea keels approximate.

    Spikelets
    Spikelets solitary or in pairs, brown, disarticulating beneath each floret, the lower floret ♂ (perennials) or barren (annuals); glumes narrowly ovate, membranous to thinly chartaceous, ± persistent, 3-nerved, the upper as long as the spikelet, the lower half as long; lower lemma lanceolate to narrowly ovate, as long as the spikelet, 3-nerved; upper lemma oblong-elliptic, membranous to thinly coriaceous, 5–7-nerved, 2-lobed, the lobes finely awned, with a tuft of hair below each lobe and a persistent awn from the sinus; callus semicircular (except T. stolziana), ± 0.1 mm. long; palea with the keels finely nerved, not winged, glabrous or with a few hairs between the keels; stamens 2
    Fruits
    Caryopsis lanceolate, glabrous, the hilum linear.
