Notes.

This section includes the famous and perennial species Papaver orientale L. and two more species according to most studies, including the recent monographic treatments by Lack (2019 a, b), who argued convincingly why the name P. pseudo-orientale (Fedde) Medw. should be conserved. Solomon et al. (2014) accepted P. lasiothrix Fedde as an additional species. However, this had been rejected in a study on Iranian species, which treated it as a synonym of P. bracteatum Lindl. ( Tavakkoli and Assadi 2013) , a conclusion also reached by Lack (2019 a) and POWO (2023). The new species Papaver yilderimlii Ertekin was described from a single site in the province of Siirt in Türkiye as similar to P. lasiothrix , except for smaller and globose capsules ( Yıldırımlı and Ertekin 2008). Papaver yilderimlii was accepted by POWO (2023), but not treated by Lack (2019 a, b) nor in other recent studies dealing with this complex. It is treated here as a synonym of P. bracteatum . The species concept in the section was also confirmed by a study on morphology, phylogeny and chemistry in Türkiye ( Parmaksız and Özcan 2011). In contrast, another Turkish phylogenetic study which applied ISSR markers ( Gürkök et al. 2013) did not clearly sort out the given sample names over the major clades.
