“…Papaver sect. Meconella has a circumpolar arctic distribution, but also occurs in the alpine and subalpine belts of several temperate mountain ranges, as well as in steppes and river valleys of Central and northern Asia (e.g., Rändel, 1974;Hultén & Fries, 1986;Peschkova, 1994). The section is absent from the western Asian mountains and the Caucasus.…”

“…Papaver alpinum is diploid (summarised in Jalas & Suominen, 1991), a ploidy level documented in other species from Central Asia, Siberia, Beringia and the central Rocky Mountains (e.g., Hanelt, 1969;Rändel, 1974;Peschkova, 1994;Kiger & Murray, 1997;Petrovsky, 1999). The geographically closest relatives of P. alpinum are found in Scandinavia and the western Eurasian Arctic (P. dahlianum Nordh., P. lapponicum (Tolm.)…”

Papaver alpinum s.l. is an extraordinarily polymorphic taxon distributed throughout southern and central European mountain ranges. We tested previous hypotheses about relationships and taxonomical status of the numerous described taxa within this species or species group by applying different molecular approaches. In addition we reevaluated morphological characters used in previous taxonomic treatments in the light of the molecular results. The ancestral sequence haplotypes were widespread and dominant throughout the Alps, whereas peripheral populations in other mountain ranges were often characterised by haplotypes directly derived from the central haplotypes involving one or two mutational steps. The AFLP data corroborated the pattern of a 'centrifugal radiation' and additionally showed that most populations were genetically distinct, presumably due to the effect of genetic drift in small and isolated populations. The morphological data did not reveal clear patterns of variation; only the Pyrenean and Sierra Nevada populations differed in two nonoverlapping and presumably independent characters. Altogether, our study implies that most previous taxonomic concepts of P. alpinum s. l. were highly artificial, and that either nearly all populations have to be raised to some taxonomic rank or that, preferably, no infraspecific taxa should be recognised at all. The only segregate possibly deserving taxonomic rank, based on both morphology and genetics, is the Iberian P. alpinum subsp. lapeyrousianum.

“…(Nordhagen, 1932). All three species have until fairly recently been considered by the majority of authors as having circumpolar or nearly circumpolar ranges and being polymorphic with two or more races (e.g., Rändel, 1974;Kiger & Murray, 1997;Petrovsky, 1999;Nilsson, 2001). Several additional species have been described as closely related to P. lapponicum and/or P. radicatum, e.g., P. hultenii Knaben from North America (Knaben, 1959b; affinity outside this group, Solstad, 2009), P. laestadianum (Nordh.)…”

“…and P. radicatum s.str. are close (Solstad & al., 2003), but they have been considered as two species by most authors in recent decades (e.g., Knaben, 1959a, b;Rändel, 1974;Tolmachev, 1975;Kadereit, 1993;Kiger & Murray, 1997;Petrovsky, 1999;Nilsson, 2001). The distinctions are mainly found in leaf dissection and shape of capsule (see Nilsson, 2001).…”

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.

Die vorliegende Arbeit behandelt die Beziehung zwischen Papaver pygmaeum Rydb. aus den Rocky Mountains und dem europäischen P. alpinum L., insbesondere der Subspezies rhaeticum (Ler.) Mgf. (Sektion Scapiflora Reichenb.). Ausgehend von geographisch‐morphologischen Untersuchungen an Herbarmaterial von den Rocky Mountains und von den Alpen wird P. pygmaeum Rydb. als eigenständige Art angesehen. P. pygmaeum und P. alpinum unterscheiden sich voneinander im Umriß der Blattspreite, in Farbe und Länge der Knospenhaare, in der Blütengröße, in bestimmten Merkmalen der Petalennervatur und in der Zahl der Staubgefäße. Beide Arten scheinen einander sehr nahe zu stehen. Ähnliche Merkmale sind die Blattfiederung, die Petalennervatur und die Kapselform. Übereinstimmende Merkmale sind die Form der Blattfiedern, die Merkmale des Blütenschaftes, die Form der Blütenknospen, die Kapselbehaarung und die Chromosomenzahl. Die Beziehung zwischen P. pygmaeum Rydb. und P. alpinum L. zu den asiatischen P. croceum Ledeb. subsp. tenerum P. Hanelt und P. nivale Tolm. aus der Alpinum‐Gruppe wird erwähnt. Diese Arten stehen morphologisch P. alpinum näher als P. pygmaeum. Die Notwendigkeit experimenteller Untersuchungen an P. pygmaeum und den übrigen Wildsippen der Sektion Scapiflora Reichenb. wird betont.
