[Unconfirmed plant reports]
NOTES:
Status of the list. Please note that this is a “living” list, constantly being refined and updated. Plant species and generic circumscriptions are in constant flux as a result of molecular research, and we attempt to keep the list up-to-date via the Jepson Online Interchange for California Floristics. In addition, some plant groups at the BFS are particularly challenging and open to revision.
We have recently updated and corrected the plant list, and reported species whose presence has not been confirmed have been moved to a separate list. If you can confirm that any of these species occur (or have occurred) at the BFS, please notify the webmaster.
Conservation status. Only two plant species at the BFS have special conservation status. Berberis nevinii is on both the state and federal Endangered Species lists (State and Federally Listed Endangered, Threatened, and Rare Plants of California, April 2009, State of California Department of Fish & Game). Horkelia cuneata ssp. puberula is listed as “seriously endangered in California” by the California Native Plant Society, although this designation carries no legal protection.
Origin. The origin listing indicates whether a plant is native to the site, a California native that has naturalized or been planted on the BFS, or exotic (not native to California).
Source. In general, we have credited plant identification to more recent sightings, although others, in addition to those cited, may have also identified the presence of a given species.
Photos & descriptions. ‘BFS’ links will show plants photographed at the BFS. We eventually hope to have photographs of all the plants on the site. Photos on the BFS pages may be used for any personal or academic purposes as long as notification of use is sent to the BFS Webmaster and the image is clearly credited with ©[Name of photographer]. For higher-resolution images, please contact the photographer. Note that no photos taken at the BFS may be used for commercial purposes without the express permission of the Claremont University Consortium. You must have pop-ups enabled to view the BFS pages.
‘CP’ links will return all photographs of the listed taxon in the CalPhotos, Digital Library Project database. As indicated above, some of these taxa may not, in fact, occur on the BFS. Note that you must check the stipulations with each photograph for permissible uses of the CalPhotos images. ‘Jep’ links will return the treatment and bioregional distribution for a taxon from the Jepson Interchange online version of the online version of the Jepson Manual.
Herbarium specimens. Voucher specimens for a number of BFS plants have been deposited in several California herbaria, and the links will show the online data for those specimens.
