430202 Atriplex glabriuscula var. glabriuscula] Edmondston
Distribution
Northern Iceland: Frequent
Northern Fennoscandia: Scattered
Svalbard - Franz Joseph Land: Presence uncertain
Shrub Tundra: Scattered
Bordering boreal or alpine areas: Frequent
- Edmondston, Fl. Shetland: 39 (1845). Neotype (K): Scotland: Caithness (Keiss), 19. Sept. 1930, leg. M.L. Wedgwood (Gustafsson 1976: 15).
- Atriplex kuzenevae N. Semenova, Fl. Murmansk. Obl. 3: 366 (1956). Holotype (LE!): European Russia: the Murman area, the Rybachi Peninsula, Liinahamari, 06. Sept. 1947, leg. O. Kuzeneva and Ponomarjeva 515.
2n=
18 (2x). - Europe (N, W), Canada (E). - Numerous reports.
Not included: Welsh (2003) accepted both 2n = 18 and 36 for this species. We do not known the primary source(s) behind the report of a tetraploid number. The main tetraploid species in temperate to northern regions is the widespread, mainly non-littoral, and rather different A. patula L. (see Casual and Excluded taxa).
Geography: Amphi-Atlantic: ICE NOR RUS.
Notes: Plants assigned to Atriplex kuzenevae from the Rybachi Peninsula in northwestern European Russia (LE) are morphologically very similar to those assigned to A. glabriuscula in the neighboring parts of northeastern Norway, see Elven (1984a). We consider them the same species.
A non-flowering Atriplex has been collected once on Bear Island (Norway, as a native casual almost certainly brought there incidentally by sea currents). The material (UME) belongs to either A. glabriuscula or A. longipes subsp. praecox but is too young for identification.
Solstad and Elven: Atriplex glabriuscula and A. longipes subsp. praecox have both been reported from Iceland (Kristinsson 1987, 2008). The inspected, mature herbarium material (AMNH, ICEL) belongs to A. glabriuscula but see A. longipes below.
