Species limits in the genus are poorly understood, despite the plants' long history of use in traditional herbal medicine and food across their range.

We found no evidence for the occurrence of other species in Iraq, including a putative new entity reported for the region. Our work highlights inconsistencies in the literature, and underscores the importance of examining multiple stable characters for delimiting species in the genus .
