According to Riedl (in Osterr Bot. Zeitschr. 109.49.1962) the subsp. desertorum Riedl from Iraq differs from subsp. linearifolia in the fruiting calyx being broader at the base (up to 10 mm). The former is also confined to Iraq. The type subspecies is characterised by the anthers which arise at the same level, forked style with 2 stigmas only and the accrescent calyx prominently nerved.
