From the Greek eremos “solitary”, and chloa “grass”, referring to the solitary raceme.
About 9 species that are native to Asia and Australia. Plants perennial, caespitose, sometimes stoloniferous. Culms 10-70 cm, herbaceous, erect to
decumbent, basal branching extravaginal. Leaves not aromatic. Sheaths open. Auricle absent. Ligule membraneous, truncate. Blades flaccid, linear to lanceolate.
Inflorescence terminal, of long-pedunculate, solitary, 1-sided racemes axillary racemes occasionally present with more than 1 spikelet unit; raceme internodes
clavate, glabrous; disarticulation in the rames. Spikelets in heteromorphic sessile- pedicellate pairs, pedicellate spikelets absent or rudimentary. Sessile spikelets
imbricate, not embedded in the raceme axes, dorsally compressed, with 2 florets, unawned; callus truncate. Glumes dissimilar, exceeding the florets. Lower glumes 4-
9-nerved, 2-keeled, keels with spinelike projections and often winged distally, smooth between the keels, margins folded inward. Upper glumes often shorter than the lower
glumes, 3-5-nerved, keels entire. Lower florets staminate. Lower paleas present; upper florets bisexual or pistillate. Lemmas and paleas hyaline, unawned. Anthers 3.

Plants perennial, caespitose. Culms 10-60 cm long, erect, or geniculately ascending. Nodes glabrous, or bearded. Sheaths keeled. Ligule up to 1 mm long, an
eciliate membrane. Blades 4-11 cm by 2-3 mm, margin glabrous, apex abruptly acute, the surface glabrous, or pubescent. Inflorescence composed of racemes. Racemes
single, arcuate, unilateral, 2-6 cm long. Rhachis fragile at the nodes, flattened, glabrous on surface, ciliate on margins; internodes clavate, 3 mm long. Spikelets
appressed, in pairs. Fertile spikelets sessile, 1 in the cluster. Companion sterile spikelets pedicelled, 1 in the cluster. Pedicels narrowly elliptic, up 2.5-3 mm long.
Fertile spikelets comprising 1 basal sterile florets, 1 fertile florets, without rhachilla extension; elliptic, dorsally compressed, acute, 3.5-4.5 mm long, falling entire; callus
glabrous, or pilose; base truncate, attached transversely. Sterile spikelets: companion sterile spikelets represented by barren pedicels. Glumes dissimilar, exceeding apex of
florets, firmer than fertile lemma. Lower glume elliptic, as long as spikelet, chartaceous, 2-keeled, no wing, 7-nerved; primary nerves pectinately ciliate; surface
flat, glabrous, or pilose; apex acute. Upper glume lanceolate, chartaceous, 1-keeled, winged on keel, 3-nerved; apex acuminate. Florets: basal sterile florets male, with
palea; lemma oblong, 3.5 mm long, hyaline, ciliate on margins, obtuse; palea as long as lemma. Fertile lemma oblong, 2.5 mm long, hyaline, no keel, no nerve; apex
obtuse. Palea 0.1-0.8 times of lemma, hyaline. Anthers 3, 1.5-2.3 mm long.
