Comments:



(1) The demarcation between the both subspecies in Canada is tentative and needs specificaton based on studies of large herbarium collections. In 'Arctic Flora of the USSR' (Vinogradova 1980), subsp. pumila is not recorded from arctic Canada and Greenland, which sharply contrasts with the situation in arctic Asia and the Alaska-Yukon sector. So, we should show on table in part A also the distribution of the whole species A. polifolia (including subsp. pumila, but not A. glaucophylla). (Yurtsev)

(2) In the geographic part this will be done in all cases where there are two or more subspecific entities, and probably also for all species aggregates. (Elven)

As in many other cases, there are evident differences between southern and northern plants. A sufficient documentation of discontinuity in the morphological and genetic variation pattern is, however, absent. There is an evolutionary problem with two (or more) nearly circumpolar zonal subspecies (or in other cases species). Such a model implies that the differentiation into two entities took place before the migrations resulting in two circumpolar patterns. The other and much more plausible hypothesis is that the differentiation of a northern boreal / southern arctic race has taken place after the species became circumpolar and then obviously as some kind of ecotypical adaptation to the colder zones. The northern entity would then be highly polyphyletic, ecotypical, and as most worthy of varietal rank. I am therefore very reluctant to accept subsp. pumila as a subspecies; at most I could accept a variety and even that with problems. (Elven)

WARNING! Subspecies might be omitted if not well justified.

Comments:

(1) The differences between A. glaucophylla and A. polifolia seem to me to be too small for status as species, and mainly quantitative. Geographically, the former appear as a northeastern American and Greenlandic race of the latter. I propose that we follow Hultén and treat the 'glaucophylla' entity as a subspecies. (Elven)

(2) The subspecific combination of Hultén (1948) is insufficient as year and place of publication of the basionym is lacking. (Elven)

(3) Possibly as a subspecies. (Yurtsev & Elven)

Comments:

(1) In the Arctic, mostly or exclusively subsp. nana (Khokhryakov & Mazurenko 1991). (Yurtsev)

(2) The record of Arcterica nana (Maxim.) Makino for the arctic Yakutia (delta of Lena River) is an evident mistake, based on the mixture of herbarium labels (in MW). (Yurtsev)

(3) If we accept a subsp. nana, it should be treated fully with a formal entry. However, I suspect it is another case of a northern zonal subspecies and we should probably only include it in synonymy, with a comment that justifies our formal exclusion of it. (Elven)

Comments:

(1) Löve & Löve (1975) record subsp. coactilis (Fern. & Macbr.) Á. Löve, D. Löve & Kapoor for the American Arctic as vicarious to the European-Siberian subsp. uva-ursi. The status of the former and its distribution needs specification. (Yurtsev)

(2) The only formal differential character given by Hultén (1968) separating subsp. uva-ursi and subsp. adenotricha is indumentum (glandular in the latter, not in the former). Two other subspecies are also given (for the Yukon Territory) by Packer & Denford (1974): subsp. stipitata and subsp. longipilosa, these too based only on indumentum differences. A last entity based on the same type of criteria is subsp. coactilis, given as arctic by, e.g., Löve & Löve (1975). As subsp. adenotricha (and also subsp. coactilis) is fully sympatric with subsp. uva-ursi, I am very sceptical to accepting them. Wells (1989, Madroño 35) found the indumentum variation to be mainly intrapopulational and neither could he confirm the ploidal difference indicated by Löve & Löve. His renaming of these entities as formae seems well founded. Until there is a good genetic documentation, and a morphological analysis also outside North America, my opinion is that we should just accept the species and reduce all other names to synonymy.

Comments:

(1) The variation in this species is large. It may, however, be difficult at this stage to construct a consistent 'taxonomy' that can be applied throughout the arctic and boreal zones. Three ploidy levels are present, but their connections to the named races are not sufficiently documented. Subsp. microphyllum has repeatedly been counted as diploid (2n=24) and this number is proved from the Arctic as well as much more southern mountains (e.g., in SE Europe). Plants morphologically similar to 'microphyllum' replace subsp. uliginosum in the Fennoscandian mountains but these have been counted as tetraploid (2n=48, Borgen & Elven 1983, Nord. J. Bot. 3: 301-306). They probably represent the plants described as subsp. alpinum (Bigelow) Hultén and mapped as such in the Fennoscandian mountains by Hultén (1968). Inclusion of this 'race' in subsp. microphyllum, as done by Yurtsev in this draft, makes that subspecies di  and tetraploid. To keep them apart as taxa is, however, difficult from morphological reasons. If the plants described as subsp. pedris really are consistently hexaploid (2n=72), this is a supporting argument for that entity as a separate race, but the number of supporting counts seem to be low. The subsp. vulcanorum proposed by Yurtsev in this draft is unknown to me and I have no opinion, except that it needs some more justification than that given in the draft before we can accept it.

The Oxycoccus palustris aggregate (O. microcarpus, O. palustris)

Comments:

(1) Aggregate and comments needed if the two species are retained. See also Vander Kloet (1983, Rhodora 85: 1-43).

The differences between O. palustris and O. microcarpus are small, but not only quantitative. They are, however, very different to keep consistently apart in Fennoscandia. Intermediate chromosome numbers are also known and gene exchange via the triploid level is possible. In Fennoscandia they behave like two races: a southern one ('palustris') that mainly is absent from the North Boreal and further north, and a northern one ('microcarpus') that reaches south to the Mid Boreal but is rare in the South Boreal. The plant described as O. palustris subsp. microphyllus seems, from the description, to have the main morphology of O. microcarpus but the chromosome number of O. palustris. It might be a case of introgression from O. microcarpus into O. palustris in a separate area, northeastern North America and Greenland. Its status should be discussed before acceptance. Note that Lange (1887) described it without reference to, and perhaps without knowledge of, O. microcarpus. (Elven)
