Species description:
Species name referring to the very long trailing plants.
Sporophytes frequent, reddish-brown, maturing in early spring.
Sometimes called Stokesiella praelonga, Eurhynchium stokesiior Eurhynchium praelongum, all of which are synonyms.
Distinguishing characteristics:
The slenderly branched, multipinnate plants that occur frequently in swampy depressions in forests and bear heart-shaped, sharply pointed, somewhat squarrose stem leaves are dis­tinctive in most populations but the wide habitat tolerance of the species is often reflected in considerable variation in its growth form. The long-snouted operculum and rough seta are also useful characters.
Loose to dense mats of light to dark green, somewhat arched, interwoven, much-branched shoots, sometimes densely branched with the main branches also bearing slender branchlets.
Similar Species:
See also notes under K. oregana and Hylocomium spendens. From species of Brachythecium, the more complex branching of Kindbergia, as well as the squarrose stem leaves are usually enough to separate it. From Eurhynchium pulchellum the blunt leaves of the Eurhyn­chium are usually diagnostic. Bryhnia hultenii, extremely rare in British Columbia is similar but occurs on logs subject to flooding; the leaves, however, are abruptly narrowed to a point, are never squarrose and pos­sess rather swollen, thin-walled alar cells, features absent in the Kind­bergia.

Habitat / Range

Most frequent in damp, swampy forest sites, around springs and in swampy depressions from sea level (indeed, on maritime rocks) to sub- alpine elevations; also on rotten logs, epiphytic on tree trunks and on rock.
World Distribution

Circumpolar in the Northern Hemisphere, also in the Southern Hemisphere, in Australasia and South America; in eastern North America from southern Newfoundland, Ontario and Nova Scotia (where rare); in the west from southeastern Alaska to California and eastward to western Montana and Nevada, where often abundant.
