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> |tables= |references={{Treatment/Reference |id=kimber1987a |text=Kimber, G. and M.
