Several names in the widespread arctic and northern boreal complexes of Papaver lapponicum–radicatum, P. nudicaule s.l., P. pulvinatum s.l., and related species are without identified or formally selected types. This absence of a nomenclatural standard has sometimes made the application of these names contradictory among authors. Lectotypes are designated for the following names: Papaver angustifolium, P. lapponicum subsp. orientale, P. minutiflorum, P. nudicaule var. labradoricum, P. pulvinatum, P. pulvinatum subsp. tschuktschorum, and P. radicatum subsp. occidentale. A previously designated lectotype for P. pulvinatum subsp. lenaense is rejected on the grounds that it was based on inadmissible material and a new one is designated. A holotype of P. nudicaule subsp. gracile is identified.
