From a fresh field investigation, it has been ascertained that the Late Palaeozoic Yu'erhong (Yüerhhung) flora from Yu'erhong, Yumen, Gansu, northwestern China, studied by Bohlin in 1971 includes plants from the Westphalian Yangfukou Formation and the Stephanian to Sakmarian Taiyuan Formation. The Yu'erhong flora from the Yanghukou Formation is dominated by Euramerican elements with a few elements of the Cathaysian flora. No Angarian elements have be found in this section for lack of Late Permian strata. The specimens studied by Bohlin might possibly come from the upper part of the Upper Permian at tne southeastern corner of the Yu'erhong basin. Those fossils from different horizons and localities might be mixed with each other during collection; so they fail to reflect the exact horizon of certain plant fossils.
