Collomia linearis



Endangered (Federal)
Red List (Provincial)


Slender Collomia is an annual herb that has a branched stem, spreading at the base and sometimes ascending toward the tip, and can reach a height of 15 cm. The leaves are alternate, elongate, and narrow, measuring 1 to 5 cm long and 1.5 mm wide. The pinkish to white flowers grow singly or in pairs at the forks of the branches, at the branch tips, or in the leaf axils.


The Slender Collomia occurs in areas of British Columbia that consist of eroded, steep, southeast-facing slopes. The sites are covered in sparse vegetation, which consists of a variety of herbs and shrubs, with scattered Douglas-fir and Ponderosa Pine.
