Primula sect. Dodecatheon is a section of herbaceous flowering plants in the family Primulaceae. Primula species in this section were formerly placed in a separate genus, Dodecatheon. The species have basal clumps of leaves and nodding flowers that are produced at the top of tall stems rising from where the leaves join the crown. The genus is largely confined to North America and part of northeastern Siberia. Common names include shooting star, American cowslip, mosquito bills, mad violets, and sailor caps. A few species are grown in gardens for their showy and unique flower display.
Orobanche uniflora, commonly known as one-flowered broomrape, one-flowered cancer root, ghost pipe or broomrape, is an annual parasitic herbaceous plant.

The name "orobanche" can be translated to "vetch-strangler" and "uniflora" can be translated to "single-flower".

It was later described by Asa Gray, the father of North American botany.

It is endemic to San Clemente Island, one of the eight Channel Islands of California. It is known from only about four kilometers of rocky coastal cliffs on the edge of the island. The plant was thought to be extinct until a few specimens were rediscovered in 1979. Only 200 individuals were tallied in a 1996 survey. In 1997 the plant was listed as an endangered species on the federal level.
Lithophragma parviflorum is a species of flowering plant in the saxifrage family known by the common name smallflower woodland star. It is native to much of western North America from British Columbia to California to South Dakota and Nebraska, where it grows in several types of open habitat. It is a rhizomatous perennial herb growing erect or leaning with a naked flowering stem. The leaves are mainly located low on the stem, each cut into three lobes or divided into three lobed leaflets. The stem bears up to 14 flowers, each in a cuplike calyx of red or green sepals. The five petals are bright white, up to 1.6 centimeters long, and usually divided into three toothlike lobes.

Lithophragma trifoliatum is a variety of flowering plant in the saxifrage family known from the western slope of the Cascade Range and Sierra Nevada in California. It is sometimes considered its own species based on the pink, fragrant flowers, the shape of the hypanthium, and other characters. Others consider it to be a sterile variety of L. parviflorum that likely now persists by vegetative reproduction.
