Analyses of newly collected, living materials from the “classical locations” led to taxonomic conclusions differing from the last comprehensive treatment by Wendelbo in the “Flora Iranica”:Allium bakhtiaricumis a good species characterised by reticulate bulb tunics; it is rather widely distributed in the Zagros mountain range. InAllium jesdianumreticulate bulb tunics are missing, and it occurs only in the mountains near Yazd. Both taxa possess a scape which is prominently ribbed in its lower part. On the contrary,Allium stipitatum(syn.A. hirtifolium) has a scape completely smooth in the living stale, and bulb tunics disintegrating in fibre‐like parts.Allium altissimum, which is only doubtfully recorded for Iran, and some other taxa formerly included within sect.Megaloprasonby Wendelbo, were not seen as living plants; their classification is shortly discussed. A new key to sect.Megaloprasons. str.
