|Phacelia stellaris with a swiss army knife for scale|
Phacelia stellaris is considered rare by the California Native Plant Society and is a candidate for listing under the Endangered Species Act by the US Fish and Wildlife Service. This species is of concern because it is known from just a few location in southern California, US, and in Baja California, MX. Many of the occurrence are considered historic; that is they haven't been seen in over 30 years. In fact many haven't been seen in over 80's years, since the 1920's and 1930's. One population that was recorded to be in the bed of the San Diego River is presumed to have gone extinct because it hasn't been seen since 1882!
