The list of populations shows the distinct populations identified by the CNPS-EB Rare and Unusual Plants Committee. The locations in this list are very general. More specific location details can be obtained from the links in the Observations section (for some of these links, a login is required).

Font

Populations in bold type have precise coordinates available for field volunteers and researchers.

Populations in normal type are only known from a description of the location; no precise coordinates are available.

Background

Populations with a white background have been observed in the last 25 years.

Populations with a blue background have not been observed for at least 25 years.

Populations with an orange background have an uncertain location or identification, or are planted.

Columns

Pop ID is a label that identifies the population. Many locations have more than one population of a species, and the population ID is used to distinguish them.
