860401 Eurybia sibirica (L.) G.L. Nesom
- G.L. Nesom, Phytologia 77: 261 (1995). - Aster sibiricus L., Sp. Pl.: 872 (1753). Lectotype (LINN): Siberia. Herb. Linn. 997.13 (Semple in Jarvis and Turland 1998: 354).
2n=
18 (2x). - Europe (N), Russia (N), Siberia (N), Far East (N, S), Alaska, Canada (NW, W). - Numerous reports.
Geography: European (N) - Asian (N/C) - amphi-Beringian - Cordilleran.
Notes: Tamamschjan (1959) accepted three species within Aster sibiricus s. lat.: A. sibiricus s. str. in southern Siberia, A. subintegerrimus in northern Europe and northern and eastern Siberia, and A. richardsonii in the Russian Far East (and North America). Barkalov (1992) mapped A. sibiricus and A. subintegerrimus (probably A. richardsonii) as largely sympatric in the northern Russian Far East. Hultén (1968b) was very reluctant to accept the division and included A. richardsonii and A. subintegerrimus in A. sibiricus. The name "richardsonii" refers, according to Nesom (1994), to Eurybia sibirica var. gigantea which he accepted besides var. subintegerrima and var. sibirica.
The species is obviously polymorphic and some taxonomy is involved. We accept, under the varietal names, the two proposed taxa that reach the Arctic. Subspecific combinations have not yet been made within Eurybia. Brouillet (2006e) discussed the variation and names but refrained from accepting races, perhaps because only one is present in North America.
