fourni par wikipedia EN

Carex deweyana[1][2][3][4][5][6][7] Dewey's sedge,[6][7] short-scale sedge,[7] is a species of sedge native to Canada[7] and the United States.[6][3]

Description

Carex deweyana grows in dense tufts, with relatively wide( .6 to 4.2 mm) leaves produced on shorter stalks near the base.[8][9][3] Culms bearing the flowering spikes are longer, up to 100 cm long.[8][9][3] These stalks fall outwards as the fruit matures.[4][8]

Range

Carex deweyana is native to central and northern North America.[5] Populations to the southern part of the North American range are confined to mountainous areas.[9][5]

The species has been introduced to Great Britain.[5] It is infrequently found as a wool alien[10]

Habitat

Carex deweyana grows in association with trees.[4][9][8] It is found in dry to moist sites.[4][9]

Ecology

Golden-crowned sparrow, Fox sparrow, Lincoln's sparrow, Song sparrow, and Dark-eyed junco have been observed in association with Carex deweyana,[11] Carex deweyana is the host of the smut fungus Anthracoidea deweyanae, in the family Anthracoideaceae.[12] [13]

Etymology

The specific name 'deweyana' commemorates Chester Dewey (1784-1867), an American naturalist.[14]

Taxonomy

The name Carex deweyana was first published in the Annals of the Lyceum of Natural History of New York, 1: 65 in 1824 in an article written by Lewis David de Schweinitz.[2] The type locality of this species is identified as New England.[2] Carex deweyana belongs to Carex sect. Deweyanae.[3]
