Comments

Eurybia sibirica is known from the northern Rocky Mountains and the northern Pacific Coast northward, becoming frequent in Alaska, Yukon, and in the boreal forest region of the continental Northwest Territories; it crosses into Siberia to reach Scandinavia (R. Elven 1989). In British Columbia, northern individuals belong to E. sibirica, not E. pygmaea (contra G. W. Douglas et al. 1998–2002, vol. 1), and southern specimens sometimes are E. merita. G. L. Nesom (1994b) recognized three varieties, two of which have been reported from North America (var. sibirica and var. gigantea). At present, however, given the great phenotypic plasticity of this species, it appears preferable not to recognize varieties, pending studies on the validity of these entities. Eurybia sibirica has often been confused at its southern range limit with E. merita, from which it differs by its often more low-cespitose habit (versus more erect habit, but smaller individuals may be similar in this respect), usually more serrate leaves (versus subserrate to nearly entire), and subequal, foliaceous, purplish phyllaries (versus unequal, non-foliaceous, purple-margined). At the southern end of its range, near the Canada–United States border, E. sibirica is usually found at higher elevations than its congener, there at its northern limit. Aster sibiricus forma albinus Lepage is merely a color variant of the species and is not recognized here.

Heads 1–50, borne singly or in open corymbiform arrays. Peduncles villous; bracts 0–3, sometimes immediately subtending heads, lanceolate or spatulate to linear-lanceolate, leaflike or phyllary-like distally (bases indurate, margins purplish), mostly foliaceous, villous. Involucres campanulate, 6–9 mm, shorter than pappi. Phyllaries 30–80 in 3–4(–5) series, sometimes wholly purplish, usually ± oblong-lanceolate to oblanceolate, sometimes linear-lanceolate (innermost), subequal or ± unequal, membranous, bases indurate, ± rounded, dark green zones lanceolate or truncate at base, in distal 1 / 3 – 4 / 5 + (outer, often foliaceous, sometimes bractlike and surpassing involucres) to 1 / 4 – 2 / 3 (inner), margins hyaline, often purplish, narrowly scarious, erose, densely villoso-ciliate, apices squarrose, acute, apiculate, faces villous. Ray florets 12–50; corollas white to pale violet or purple, 7–17.5 × 0.8–1.8 mm. Disc florets 25–125; corollas yellow becoming purplish, 5–8.1 mm, slightly ampliate, tubes longer than funnelform throats, lobes erect, triangular, 0.5–1.1 mm. Cypselae brown, fusiform, compressed, 2.5–3.7 mm, ribs 7–10 (stramineous), faces strigillose; pappi of dark cinnamon or reddish tan (sometimes apically clavellate) bristles 5.5–7.5 mm, ± equaling disc corollas. 2n = 18.

Eurybia sibirica

Eurybia sibirica, commonly known as the Siberian aster or arctic aster, is an herbaceous perennial native to north western North America and northern Eurasia, stretching from Scandinavia to Canada. It is found largely in open areas of subarctic boreal forests, though it is also found in a wide variety of habitats in the region. It is similar in appearance to Eurybia merita, but their ranges only overlap near the border between the US and Canada, where E. sibirica is generally found at higher elevations. The flowers emerge in the summer and display white to pale purple ray florets as well as and yellow disc florets that become purplish as they mature.

Distribution and habitat

E. sibirica is present in much of the subarctic region of world, from western North America through Siberia and to Scandinavia. Its range stretches from the northern Rocky Mountains beginning in the south in Idaho and Montana, north to the Canadian provinces of Alberta and British Columbia, farther into the North West Territories and Nunavut, west to Yukon and Alaska,[2] across the Bering Strait into Siberia and continuing west through Russia and into Norway.[3] It is found at heights ranging from sea level up to 2200 metres in sandy or gravely soils in disturbed or open areas of boreal forests. It is also present in wet meadows, in open areas of aspen and spruce woods and along riparian thickets. In addition, it is common growing in sandy or gravelly stream flats, along stream banks and the shores of lakes, on bluffs, in sand dunes and other sandy places, and in both sub-alpine and mountain meadows.[2]

Names and Taxonomy

Taxonomy

Comments: Under Kartesz's (1999) treatment, this taxon excludes material that he formerly (1994) included in Aster sibiricus as Aster sibiricus var. meritus, and A. sibericus var. giganteus. (It apparently includes some, but not all, of the material he treated as A. sibericus var. pygmaeus in 1994.) Thus, Eurybia sibirica is narrower in concept than Aster sibiricus in the Kartesz 1994 sense.
