--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>annual. <b>Culms</b> 14-80 cm, usually glabrous, erect or geniculate at the base, with (1)2-4(5) nodes. <b>Sheaths</b> open; auricles ciliate; ligules 0.2-0.8 mm, membranous, truncate; blades 1.5-10 mm wide, linear to linear-lanceolate, flat, spreading. <b>Inflorescences</b> terminal spikes, with 2-13 spikelets, usually with 1-3 additional rudimentary spikelets at the base; internodes 6-12 mm; disarticulation either at the base of the spikes or in the rachises, the spikelets falling attached to the internodes above or below. <b>Spikelets</b> solitary at each node, 72-2(3) times the length of the internodes, tangential to the rachis, appressed or ascending, the upper spikelet(s) sometimes sterile; fertile spikelets 5-15 mm, with 2-7 florets, the distal florets often sterile. <b>Glumes</b> ovate to rectangular, rounded on the back, scabrous or pubescent, with several prominent veins, midveins smooth throughout, apices truncate, toothed, or awned, sometimes indurate at maturity; lemmas rounded on the back, apices toothed, frequently awned; paleas chartaceous, 2-keeled, keels ciliate; anthers 3, 1.5-4 mm, not penicillate; ovaries with pubescent apices. <b>Caryopses</b> lanceolate to lanceolate-ovate, x = 7. <b>Haplomes</b> B, C, D, S, T, U, M, N.</span><!--

|discussion=<p><i>Aegilops</i> has about 23 species, and is native to the Canary Islands, as well as from the Mediterranean region to central Asia. It is sometimes included in <i>Triticum</i> because the two form natural hybrids and both are involved in the evolution of the cultivated wheats, including <i>T. aestivum</i>. They are treated as distinct genera here, in keeping both with past practice and with their differing ecological attributes, <i>Aegilops</i> being a weedy genus.</p><!--
--><p>Four species are established in the Flora region; only <i>Aegilops cylindrica</i> is widespread. The introductions occurred at the end of the nineteenth or beginning of the twentieth century. Three other species have been collected in the region; they are not known to have persisted.</p><!--
--><p>In the key and descriptions, spike and spikelet lengths exclude the rudimentary spikelets and awns.</p>
