Taxonomic Comments

Several varieties of Juncus effusus have been recognized as deserving recognition at a higher rank, and Snogerup et al. (2002) newly combine J. hesperius, elevating J. effusus var. brunneus as recognized by Kartesz (1994, 1999). Treatment at the species-level was maintained by Kirschner (2002) and Zika (2013), the latter noting this taxon is treated as a segregate of J. effusus and "treated at the rank of species here, as they retain their morphological differences when sympatric with J. effusus subsp. pacificus at many sites, and intermediate morphology is quite scarce in the field and herbarium." In contrast FNA (2000, vol. 22) did not recognize J. hesperius or varieties of J. effusus, noting, "The Juncus effusus complex has been variously recognized as containing several species or a single species with numerous infraspecific taxa. Unfortunately, North American treatments have dealt primarily with taxa in either the eastern or western portions of the continent. In considering the continent as a whole, little sense can be made of these treatments."

Range Extent Comments

Juncus hesperius occurs in western North American "coast from Queen Charlotte Island in British Columbia to near Santa Barbara in California" (Kirschner 2002).

Ecology & Habitat

Habitat

"Juncus hesperius is primarily coastal, but penetrates inland along the Columbia River, as well as ascending some hills in the Coast Ranges of Oregon and California. The species ranges from sea level to 735 m elevation, on damp to wet sandy, peaty, or gravelly substrates, in full sun or partial shade. Natural habitats include marshes, peatlands, shores, riparian zones, swamps, wet meadows, wet prairies, old growth forest, and freshwater springs in coastal dunes or salt marshes. It is a successful colonist of exposed damp or wet soil in pastures, ditches, trails, logging clearings, disturbed ground, and cranberry farms" (Zika 2013).
