Comments:

(1)A very complex genus where the species are sexual (usually with both sexes present in populations), agamospermic (usually only females present in populations), or sometimes both (as, e.g., in A. alpina s. str. and some entities in A. friesiana s. lat.). The genus has been split extensively on the American and Greenlandic side, at the time of Hultén (1952) about 200 North American 'species' had been described, less so in Asia and Europe where the variation is much more restricted. There are probably basal sexual entities (species?) and an upperstorey of agamospermic offspring that may have originated directly from the sexuals and/or perhaps as results of hybridisation between sexuals.

In principle, we should try as far as possible to separate between the basal sexuals and the apomicts. The latter we should try to group according to origin, those developed directly from single sexuals within a species (perhaps as subspecies), those with an origin from two or more sexuals as separate entities in some larger, functional groups. At present, this is impossible as only a part of the genus has been sufficiently analysed.

The most thorough treatment yet is found on the American side, by R. Bayer, also reflected in Bayer's treatment in Cody (1996). It followed a tradition from Hultén (1968) and accepted wide species with with sexual and agamospermic subspecies. This has been accomplished, more or less, for three of the main aggregates the A. rosea, A. friesiana and A. monocephala aggregates, but not for the large A. alpina aggregate or the NE American Greenlandic group of entities around A. affinis and A. hansii. It can therefore not be applied consistently yet even if it is a valid and probably efficient approach and also acceptable according to our checklist principles. Treatment as subspecies in parts of North America and as species elsewhere would give a wrong impression of the evolutionary situation. I have therefore gone for listing of species names as first choice in the aggregates, of course with the subspecific combinations as synonyms.

Four sections are indicated and seem to be valid groups: Dioicae, Alpinae, Plantaginifoliae, and Carpaticae. The two former might, however, be problematic as some agamospecies are said to link them. (Elven)

Sect. Dioicae ***

Comments:

(1)Only one species is recognised in the arctic Eurasian parts. The related Fennoscandian A. nordhageniana Rune & Rønning does not reach the Arctic even if it comes fairly close. The variation in North America seems to be formidable. Porsild (1951) accepted 12 species in Yukon alone and Hultén (1952) 14 species in Alaska Yukon but none in the arctic parts. There is also a significant diversity in the group in NE America and Greenland. The group there may represent a 'species' with several subspecies. (Elven)

Sect. Alpinae ***

Comments:

(1)About 20 species names are currently applied in this section in an arctic context, the majority in North America and Greenland. I have tentatively tried to group them into three aggregates which might be comparable to the aggregate species in Bayer's concept: the broadly amphi-Atlantic A. alpina s. lat. (the A. ungavensis aggregate in Scoggan's concept) and the mainly North American (Greenlandic) and amphi-Beringian A. friesiana s. lat. and A. monocephala s. lat. (Elven)

Comments:

(1)Bayer in Cody (1996) treated this aggregate collectively, probably because it was difficult to analyse it on North American representatives alone. It should be treated in the same way as the A. friesiana and A. monocephala aggregates but that is currently not possible.

Bayer applied the collective name A. alpina also for some NW American and amphi-Beringian entities. I am not sure that is the best solution and have tentatively transferred these entities 'compacta', 'cryomophylla' and perhaps 'subcanescens' to the A. friesiana group. (Elven)

Comments:

(1)Male plants occur in low frequency, often localised in certain areas. Functional pollen seems to be rare or absent, and the species is probably mainly agamospermic. This is still a very heterogeneous species but no thorough analysis has been undertaken in the amphi-Atlantic area. The question mark for Russia refers to records from Rybachi Peninsula in the Murman area. The question marks for Iceland, Canada and Greenland refer to doubts about presence of this agamospecies in the western hemisphere; it may be replaced here by A. canescens (see below). Hultén & Fries (1986) mapped A. alpina s. str. only for Fennoscandia whereas all plants from Iceland westwards were mapped as A. canescens. (Elven)

(3)Antennaria densifolia A.E. Porsild (1945), Bull. Natl. Mus. Canada 101, Biol. ser. 30: 26, has been indicated as a synonym of A. compacta. This is probably not right. Both sexes are present in the populations of Antennaria densifolia and it is probably sexual (Bayer in Cody 1996). It is treated as a separate species by Bayer. It is not present in the Arctic as its northern limit seems to be in Mackenzie Mts. This entity should therefore be omitted also from synonymy. (Elven)

We should probably follow that and accept some polymorphy in this sexual entity.
