The plant is endemic to southeastern California.[1] It is known only from 12 to 14 occurrences in the Owens Valley within Inyo County and Mono County, and 2 occurrences in the Lucerne Valley area of the Mojave Desert within San Bernardino County.[2]
It can be found on mud flats and around desert springs, between 750m-2210mm (2,460feet-7,250feetm) in elevation.[1] It is found in wetland-riparian areas of Joshua tree woodland and Great Basin sagebrush scrub habitats.[2]
Plagiobothrys parishii is an annual herb growing prostrate along the ground, the stems reaching up to about 30 centimeters long. It is coated in short hairs.[1]
The inflorescence is a series of tiny five-lobed flowers each about 4 millimeters wide. The flower is white, usually with yellow appendages at the center. The bloom period is March to June.[1]
