Typification Of Names In Papaver Sect. Meconella Spach (Papaveraceae)

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.
