Oreomecon rubroaurantiaca is a plant in the family Papaveraceae, native to southern Siberia, Mongolia and northeastern China. It primarily grows in subalpine or subarctic biomes, often in high-altitude environments. Formerly known as Papaver rubroaurantiacum, it was transferred to the genus Oreomecon. This genus was established in 2022 for taxa previously treated as Papaver section Meconella to ensure that the genus Papaver is monophyletic. The genus name Oreomecon derives from the Ancient Greek oros (“mountain”) and mecon (“poppy”), reflecting the plant’s typical habitat.
