Triticum ispahanicum Heslot : Blé d'Iran, Ispahan emmer wheat, Iranischer Weizen 

Some morphological forms have unjustifiably received species status in the past and have not been reclassified as subspecies. This is true for a tetraploid long-glume variant Triticum ispahanicum Heslot (J. Dvorak, in Brenner's Encyclopedia of Genetics (Second Edition), 2013)

The many extinct Triticum species (on farm) clearly show the general tendency. The example of Triticum ispahanicum should be mentioned particularly, a wheat described only in 1958 which could not be found again during recent collecting missions (Khoshbakht, 2009), but which is still available in some collections, highlighting the value of the ex situ system. (Karl Hammer, 2011).
