Sorbus decora
species of plant
Sorbus decora, commonly known as the northern mountain ash, showy mountain-ash, Greenland mountain-ash, and dogberry, is a species of deciduous shrub or very small tree native to northeastern North America.
Description
Sorbus decora grows 4–10 metres (13–33 ft) tall. Its leaves are odd-pinnately compound, with 11–17 leaflets. Each leaflet is 5–10 cm (2–4 in) long and 1–2.5 cm (3⁄8–1 in) wide. All parts are hairless to slightly hairy. Flowers are borne in 125- to more than 400-flowered panicles 6–25 cm (2+1⁄4–9+3⁄4 in) across. Each flower is 5–7.5 mm (1⁄4–1⁄4 in) across and has five white petals 2.5–3.5 mm (3⁄32–1⁄8 in) long, 14–20 stamens, and carpels with 3–4 styles. The fruits (pomes) are bright red to orange-red and 4–7 mm (5⁄32–9⁄32 in) across.
Distribution and habitat
Sorbus decora occurs throughout the Laurentian Mixed Forest Province, the New England-Acadian forest region, the eastern Canadian boreal forests and Greenland. It cannot be found north of 62°15′N, which confines it the southern tip of Greenland, generally deeper up the western fjords, such as the Qinngua Valley.

Why this record matters
“Sorbus decora” is worth following because a concise public description often conceals a longer documentary argument. Here, Sorbus, decora and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 7, 2026. The linked authority identifier is Q966130. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
