Probably only casual occurences in the Arctic, e.g., Solanum tuberosum L. The family should probably be excluded. (Elven)

Comments:

(1) Subsp. vulgaris only occurs as a vegetatively remaining garden escape without seed propagation in arctic Norway and probably also in Greenland. It is therefore debatable whether it should be included or not. The only reported native Pechora occurrence should be checked as to status as subsp. vulgaris is comparatively thermophilous. The Pechora occurrences are mapped as subsp. acutiloba by Hultén & Fries (1986). (Elven)

89.5  Lagotis P. Gaertn. ***

Comments:

(1) The data concerning the two entities listed below are conflicting. Hultén (1968) considered them as subspecies in Alaska as he reported that "transitions between the two races occur frequently where the ranges overlap". He also recognised L. hultenii as a separate species in NE European Russia and NW Siberia. This opinion was not shared by Webb (1976, Fl. Eur. 3) who restricted L. minor to NE European Russia and Siberia, an opinion also reflected by Hultén & Fries (1986) as they mapped L. minor (as species) only in some smaller areas of European Russia and Siberia and excluded it from North America. It would perhaps be better to treat the two listed entities as subspecies as done by Petrovsky in Tolmachev & Yurtsev (1980) and I have changed accordingly. (Elven)

Comments:

(1) There is an evident and large variation but probably not in the plants that reach the Arctic. A correlation between ploidy level and morphology remains to be proved. The tetraploid Finnish count (Raitanen 1967, Ann. Bot. Fenn. 4) has been critically checked by Kukkonen (1986, Symb. Bot. Upsal. 27, 2) and is dubious. (Elven)

Comments:

(1) The 'pumila' (or 'australis') entity is enigmatic. The differences from 'alpina' s. str. race are small but constant in stem, bract and especially in fruit indumentum, there are also differences in leaf shape and denture, and the stem is almost never straight as it usually is in 'alpina' s. str. In Fennoscandia it differs both ecologically and geographically from subsp. alpina. It is restricted to open calcareous soil at high altitudes whereas subsp. alpina is indifferent and often grows in closed vegetation at all altitudes. It is restricted to the two central mountain areas in the south and north whereas subsp. alpina is more ubiquitous, but this might partly be an effect of its high-altitude preference. Intermediates have not been documented.

This race 'crops out' very disjunctly in most major mountain areas in Europe (the two names originate from W Alps and the Carpathians). According to Hultén & Fries (1986) it is the only race south of Britain and the Nordic area. Most authors treat it as a variety, but as it is a major geographic and partly allopatric entity differing in several unrelated characters and without documented intermediates, the choice is rather between subspecies and species.

Subsp. pumila is reported to occur in Iceland but I do not know the distribution. In Norway it occurs in the mountain range south of the Arctic. Occurrence in Greenland is disputed but the entity is accepted from Greenland by Böcher et al. (1978, as var. australis). (Elven)

Comments: **Check Pennell (1921, Rhodora 23 p. 15 ca) and Fernald (1939, Rhodora 41: 447-457)**

(1) The taxonomic consequences of the variation in this species is disputed. Hultén (1968) recognised two entities in NW America: the wide-ranging subsp. wormskjoldii from Greenland west to Alaska and the Cordilleran subsp. alterniflora from California to Alaska where it reaches the Arctic in Brooks Range. These were not accepted by Cody (1996). Hultén synonymised Bongard's V. nutans with subsp. wormskjoldii. However, after a ploidy variation was proved in the 1960ies, Löve & Löve (1975) separated the NW American plants as a diploid V. nutans from the NE American tetraploid V. wormskjoldii s. str. They do not mention the 'alterniflora' entity and it is not clear whether all the NW American plants belong in their V. nutans.

The differences reported between the races or species are small and mainly quantitative. We have to decide whether we shall enter them formally or keep a (very) collective species. The options for separate entities seem to be:

(a) As an eastern ('wormskjoldii') and western species ('nutans'), the former restricted to GRL and eastern CAN, the western to western CAN and ALA. The western entity then includes both subsp. alterniflora and western subsp. wormskjoldii in Hultén's meaning.

(b) Similar, but as two subspecies. Then subsp. wormskjoldii is the name for the eastern entity, subsp. alterniflora (with the 'nutans' names as synonyms) for the western entity. Both solutions (a) and (b) neglect the morphological variation found in the western plants.

(c) As Hultén (1968) with a wide subsp. wormskjoldii and a Cordilleran subsp. alterniflora. This solution probably neglects the ploidy difference.

(d) As three entities, perhaps represented by the names 'wormskjoldii' (eastern tetraploid entity, Greenland typification, CAN and GRL), 'nutans' (western coastal, perhaps diploid entity, SE Alaskan typification, ALA), and 'alterniflora' (western Cordilleran, perhaps tetraploid entity, Canadian Rockies typification, ALA).

Until further I have only entered the two entities from Hultén (1968). (Elven)

Comments:

(1) The 'humifusa' entity is geographically absurd and does not at all fit our 'rule' that an accepted entity shall have a consistent and at least theoretically explainable distribution. It occurs scattered in mountainous (but not alpine) areas nearly everywhere on the northern hemisphere (perhaps except for Russia   Siberia) and also in a very few arctic or nearly arctic areas. In addition it is found in some isolated islands (the subtropical Azores are indicated by Hultén & Fries 1986) and probably south America. The three epithets applied to it are based on plants from the British Isles (Dickson's 'humifusa'), the western Alps (Allioni's 'tenella') and North Fennoscandia (Laestadius' 'borealis'). It is not at all clear that they refer to the same taxon.

The entity is generally characterised by lower growth than subsp. serpyllifolia, efficiently rooting branches (forming carpets), shorter racemes (also in fruit), a dark brownish indumentum, presence of dark glandular hairs in inflorescence (vs. eglandular in subsp. serpyllifolia), pedicels longer than the calyx, flowers slightly larger and sky blue (vs. pale blue to white with bluish marks), and capsule with a cuneate base (vs. rounded). These differences refer at least to the North Fennoscandian and Alaskan plants. The differences are too many and presumed independently inherited to be explained by a recurrent mutation. Hybrids are fairly frequent in intermediate habitats in the few places in Fennoscandia where the entities meet and here they behave like races (subspecies). There is also a distinct eco-geographical difference, at least in Fennoscandia. Subsp. serpyllifolia is more or less ruderal and occurs throughout the area except for northern boreal woodlands and mountains. Subsp. humifusa is a specialist of northeastern boreal forest swamps, mountain swampy willow thickets and cold springs, mostly found well outside the range of subsp. serpyllifolia.

Until more evidence is available, I propose that we accept subsp. humifusa as a subspecies. Its rank has varied in more recent decades from species to variety. As to name, I am more in doubt. In Fennoscandia this is a distinctly northeastern continental and boreal taxon and we should check the British typification of 'humifusa'. (Elven)
