Camissonia subacaulis



First Noted by Expedition
June 14, 1806, on the Weippe Prairie, Idaho.
 

Description
A dandelionlike rosette of jagged-edged leaves and bright yellow flowers with four broad petals. Height: 1-4 in (2.5-10 cm).
 

Range
Soil moist in spring but drying by summer, from sagebrush plains to pine forests.
 

Note
All Camissonia have a knob on the style, a feature that separates these species from the genus Oenothera, in which they once were placed.
