Plants annual; tufted. Culms 2-15 cm tall, to 0.3 mm wide, erect. Leaves primarily basal; sheaths closed almost to the top; auricles absent; ligules about 1 mm, hyaline, truncate; blades 0.3-1 mm wide, flat or involute. Inflorescences terminal racemes, spikelike, rachises smooth, glabrous. Spikelets 1.8-3 mm, imbricate, in 2 rows on 1 side of the rachis, slightly laterally compressed, with 1 floret; rachillas not prolonged above the florets; disarticulationabove the glumes and beneath the florets. Glumes subequal, surpassing the florets, glabrous, smooth, 1-veined, rounded on the back, unawned; callusesglabrous; lemmas about 2/3 the length of the spikelets, elliptical in side view, thinner than the glumes, 5-veined, shortly and densely pubescent throughout, unawned, apices truncate, often denticulate; paleas about as long as the lemmas, 2-veined, shortly and densely pubescent between the inconspicuous keels; lodicules 2; anthers 3; ovaries glabrous; styles fused at the base, dividing into 2 feathery stigmas. Caryopses elliptical, terete, 2/3 the length of the lemma, enclosed by, but not fused to, the lemma and palea at maturity; embryos about 1/5 the length of the caryopses, elliptic; hila punctate, basal. x = 7. Name of uncertain origin.
Mibora is a genus of two species, both of which grow in damp, sandy soils. Mibora minima, the species that has been introduced to the Flora region, grows throughout much of western Europe. The second species, Mibora maroccana (Maire) Maire, is restricted to northwest Africa.
