Frasera gypsicola
Bot. GaZ. 120: 3. 1958.
Herbs perennial, 1–3.5 dm, glabrous. Stems 1–few from each division of the caudex, often with several rosettes. Leaf blades white-margined, basal 3–8 × 0.1–0.3 cm, narrowly linear; cauline leaves opposite, blades similar to basal. Inflorescences narrow but not dense, few-flowered. Flowers: calyx 3–4 mm; corolla cream, dark purple-dotted, 5–9 mm, lobes lanceolate, apex acute to short-acuminate; androecial corona scales oblong, ca. 2 mm, margins subentire to ± lacerate; style slender, distinct; nectaries and foveae 1 per corolla lobe, foveae opening ± round, distal to nectaries but without a differentiated area on the corolla surface, rim deeply, evenly fringed all around.
Phenology: Flowering summer.
Habitat: Valley bottoms, in white-barren soils.
Elevation: 1500–1700 m.
Discussion
Frasera gypsicola is endemic to two small calcareous mountain areas in northeastern Nye County and adjacent White Pine County, Nevada, and western Millard County, Utah.
Because of its multicipital caudex with the divisions more strongly divergent than in other Frasera species except F. coloradensis, F. gypsicola has a distinctive cespitose habit.
