Concept Reference: Kartesz, J.T. 1999. A synonymized checklist and atlas with biological attributes for the vascular flora of the United States, Canada, and Greenland. First edition. In: Kartesz, J.T., and C.A. Meacham. Synthesis of the North American Flora, Version 1.0. North Carolina Botanical Garden, Chapel Hill, N.C.
Concept Reference Code: B99KAR01HQUS
Name Used in Concept Reference: Hastingsia bracteosa var. bracteosa
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. The (former) U.S. federal status for "H. bracteosa" applied to var. bracteosa in the sense of Kartesz (1999), followed here.

NatureServe Global Conservation Status Factors

Range Extent Comments: Known only from central Josephine County, Oregon in serpentine wetlands around Eight Dollar Mountain, lower Josephine Creek, and Free and Easy Creek (Kagan 2006).

Area of Occupancy: 6-25 4-km2 grid cells
Area of Occupancy Comments: Approximately 25 4-sq km grid cells (EO data in the NatureServe central database as of February 2014).

Number of Occurrences: 21 - 80
Number of Occurrences Comments: Approximately 22 occurrences (EO data in the NatureServe central database as of February 2014).

Population Size Comments: Total population may be less than 70,000 individuals.

Number of Occurrences with Good Viability/Integrity: Few (4-12)

Overall Threat Impact: High
Overall Threat Impact Comments: Threatened by alterations to hydrology, mining (for nickel or chrome ore), and recreational off-road vehicle use (Oregon Department of Agriculture (2010). Other threats include fire suppression activities/altered fire cycles, water siphoning/domestic water use, and road construction/maintenance (Kagan et al. 2006). Cattle grazing is also a threat (Becking 1982 cited by Guerrant 2010).

Short-term Trend: Unknown

Long-term Trend: Unknown

Environmental Specificity: Narrow. Specialist or community with key requirements common.
Environmental Specificity Comments: Associated only with serpentine bogs.

Basic Description: A perennial herb with a few grass-like leaves and a stout stem, 4-7 dm tall. Produces a spike of white flowers from late May to June.
General Description: Arising from a bulb, this lily has numerous small dull white flowers (15 to 100 of them) cover the upper foot (3 dm) of the 16 to 28 inch (4-7 dm) bloom stems. Leaves are long and narrow, 10 to 20 inches (2.5-5 dm) long and less than 1/4 inch (7mm) wide.
Technical Description: Bulb narrowly ovoid, 4-8 cm high; stem 4-7 dm high, bearing 1-3 reduced leaves; leaves 2.5-5 dm long, 3-7 mm wide; raceme 2-3 dm long, sometimes with a few branches below, the bracts narrowly attenuate, 7-10 mm long, the stout pedicels 2-3 mm long; perianth dull white, the lanceolate, long-acuminate segments 10-12 mm long; stamens half to two-thirds as long as the perianth; style nearly as long as the ovary; capsule broadly ovoid, 8-10 mm high, barely stipitate. (after Peck 1961)
Palustrine Habitat(s): Bog/fen, HERBACEOUS WETLAND
Habitat Comments: Perennially wet meadows or bogs on serpentine soil. Often in open, lower elevation areas with gentle slopes. Dominant associated species include California pitcher-plant (Darlingtonia californica) and various sedges.
