(1986), genus (394).

Native, endemic. 1
species, from arid Queensland.

Perennial, tufted. Leaf blades narrow. Ligule a fringed membrane.

Inflorescence of spicate main branches, of digitate racemes or spikes,

Spikelets. Spikelets
dorsally compressed, 2 flowered, with 1 fertile floret, solitary (on one side
of axis); with naked rachilla extension. Fertile spikelets disarticulating
above glumes.

Glumes. Glumes
more or less equal, long relative to adjacent lemmas, pointed (acuminate),
awnless, similar (narrow, membranous, divergent, the upper deciduous). Lower
glume 1 nerved. Upper glume 3 nerved.

Fertile florets 1. Lemmas broadly rounded, decidedly firmer than glumes
(cartilaginous), entire at apex or incised (emarginate), when entire pointed or
blunt, awned, 3 nerved, hairy, 3 keeled. Awns 1, dorsal, non-geniculate, about
as long as body of lemma. Palea entire, thinner than lemma (scarious), 2
nerved. Distal incomplete florets 1 (neuter, with a cuneate lemma). Lodicules
2. Stamens 3. Grain small, ellipsoid, compressed dorsiventrally. Hilum short.
Embryo large.

Habitat. Savanna. Species of open habitats.

Chloridoideae; Cynodonteae.

Notes. Although
dorsally compressed the lemma is unlike that of Enteropogon, and the
genus probably has more in common with Chloris (Clayton and Renvoize
