Collomia tracyi
Collomia tracyi is very similar to the widespread Collomia tinctoria (see image I12-0294) but has a much more restricted range, being found only in mountains of northwest California. The two can be distinguished by the point of attachment of the filaments to the corolla tube. The different filaments are attached at more than one level in C. tracyi, but are all attached at the same level in C. tinctoria. In this plant, they seemed to be attached at different levels, and the plant did not stain as C. tinctoria is reported to, so I inferred it to be C. tracyi. The corolla tube seemed shorter than usual for C. tracyi, but this may be a variable feature. Photographed in open country at about 7,000 feet elevation on the southwest side of North Yolla Bolly, Trinity County, California, on July 15th 2017, image 1710.
