While considerable morphological research has been conducted on <i>Lepidagathis</i>, it has not completely dispelled taxonomic ambiguities and conflicting interpretations. Molecular analysis emerges as a valuable tool for resolving these taxonomic uncertainties, but the availability of nucleotide sequence data for <i>Lepidagathis</i> has been limited thus far. This study delivers a phylogenetic analysis of <i>Lepidagathis</i> species, utilizing both chloroplast and nuclear regions. The results of Bayesian Inference and Maximum Likelihood phylogenetic analyses consistently segregate the studied <i>Lepidagathis</i> species into two principal clades, denoted as Clade A and Clade B. Notably, this analysis firmly positions the Indian endemic <i>Lepidagathis</i> within Clade A, supported by robust statistical evidence. Furthermore, our biogeographical analysis strongly suggests that the origin of <i>Lepidagathis</i> might be traced back to Eurasia.

The latter is proposed here to include eight genera. Amongst these, the recently described genus <i>Oreomecon</i> is phylogenetically a sister group to <i>Meconopsis</i>, a genus from Himalaya and central China, which is reviewed here as including 95 species and 21 subspecies. By contrast, <i>Oreomecon</i> has a circumpolar northern alpine and Arctic distribution, including incompletely understood taxa, many threatened by climatic warming. Based on a review of literature and phylogenies, it is proposed here that <i>Oreomecon</i> includes 68 species and 29 subspecies. <i>Oreomeconaurantiaca</i>, <i>O.cornwallisensis</i>, <i>O.keelei</i>, <i>O.ochotensis</i> and <i>O.uschakovii</i>, 29 subspecies and four varieties are placed in <i>Oreomecon</i> here, 29 of these as recombinations, the remaining ones as nomenclatural novelties. A total of 21 existing <i>Oreomecon</i> names are placed into synonymy. The taxonomically challenging <i>O.alpina</i> group from Central Europe is treated as comprising three species, with the remaining entities positioned at the subspecies level pending further studies. The much-studied Nordic species <i>O.radicata</i> is treated with eight subspecies here, based on morphometric studies, whereas four accepted entities are provisionally recombined at the variety level.

As reviewed here, <i>Papaver</i> comprises 59 species and 14 subspecies and is only the third-largest genus in the group. Based on the distribution of its closest relatives and oldest sections, it is hypothesised here that <i>Papaver</i> arose in the western Mediterranean.
