Taxonomic Comments

Hastingsia atropurpurea and H. bracteosa are treated as distinct species by Kartesz (1994) and Flora of North America Editorial Committee (2002); in Kartesz (1999), they are each treated as varieties of H. bracteosa. Meyers et al. (2015; Flora of Oregon, vol. 1) say "neither recent molecular investigations (Hapin and Fishbein 2013) nor current morphological studies support" treatment of the varieties as distinct species. They go on to say, "The two varieties can be found sympatrically in fens in the Illinois River valley and are thought to hybridize (Lang and Zika 1997)." The Oregon Department of Agriculture (which maintains the Oregon List of Endangered, Threatened, and Candidate plant species (accessed May 2023), also recognizes H. bracteosa, including H. bracteosa var. atropurpurea as a variety. The (former) U.S. federal status for "H. bracteosa" applied to var. bracteosa, however, as of May 2023, the U.S. FWS ECOS database and ITIS accept two distinct species.

Ecology & Habitat

Habitat

Moist to wet, often open, habitats on gentle slopes (5-30 degrees), including open bogs and fens, moist open meadows, seeps/springs, and riparian wetlands, usually overlying serpentine or peridotite rock formations. Commonly associated species include Darlingtonia californica, Helenium biglovei, Rhododendron occidentalis, and Chamaecyparis lawsoniana. In serpentine Darlingtonia bogs and fens (which can be either hillslope fens or hanging fens located above the larger rivers and streams), other associated species include Gentiana setigera, Viola occidentalis, Castilleja miniata ssp. elata, Narthesium californica, Sanguisorba microcephala, Rudbeckia californica, and Tolfieldia glutinosa. In shrubby riparian habitats (which can be either along small streams or along the larger creeks and rivers), there is a greater coverage of Rhododendron occidentalis and Chamaecyparis lawsoniana than in many other locations. Other associated species include Cyprepidium californicum, Carex mendocinensis and Umbellaria californica. < 240 m.
