	Wheats form a complex arranged in a polyploid series: 2n= 2, 4 and 6x. A great many species have been described in the past, but they are much reduced now. We adopt here the concept of biological species, by including in one and the same species all the types which share the same genomic constitution. For example, spelt is ''Triticum aestivum'' subsp. ''spelta''. Other authors prefer using species names as equivalents of "crops", and then spelt is ''Triticum spelta''. Both systems are vaild, the last one having the advantage of shorter names.

 Most workers prefer letting the situation as it is, with two genera, ''Triticum'' and ''Aegilops''. This solution doesn't solve the question of species delimitation, but allows to maintain communication at a fair level.
