Template:Speciesbox

Cornus suecica, the dwarf cornel or bunchberry, is a species of flowering plant in the dogwood family Cornaceae, native to cool temperate and subarctic regions of Europe and Asia, and also locally in extreme northeastern and northwestern North America.

Description

Dwarf cornel is a rhizomatous herbaceous perennial growing to Template:Convert tall, with few pairs of sessile cauline leaves in opposite pairs, Template:Convert long and Template:Convert broad, with 3-5 veins from the base.<ref name=Stace/> The flowers are small, dark purple, produced in a tight umbel that is surrounded by four conspicuous white petal-like bracts Template:Convert long. The fruit is a red berry.

Habitat and range

Cornus suecica is a plant of heaths, moorland and mountains, often growing beneath taller species such as heather (Calluna vulgaris).<ref name=Blamey>Template:Cite book</ref><ref name=Stace>Template:Cite book</ref> Its range is nearly circumboreal, but it is absent from the continental centres of Asia and North America.<ref name=DVF>Template:Cite web</ref> In North America, the species is found in Alaska (U.S.) and British Columbia (Canada), and also eastern Canada (Labrador, New Brunswick, Newfoundland, Nova Scotia, and Quebec), as well as Greenland, but not in the intervening region.<ref>Template:Cite web</ref><ref name=plants/>

Where Cornus canadensis, a forest species, and Cornus suecica, a heath or bog species, grow near each other in their overlapping ranges in Alaska, Labrador, and Greenland, they can hybridize by cross-pollination, producing plants with intermediate characteristics.<ref>Neiland, Bonita J. 1971.
