Range Extent20,000-200,000 square km (about 8000-80,000 square miles)
Number of Occurrences81 - 300
Rank Reasons
This xeric-adapted fern occurs in rocky exposed habitat at many locations in southwestern California.It appears to have few threats. Cheilanthes clevelandii also occurs in Baja, Mexico.
Range Extent Comments
This species occurs in the coastal mountains of southwest California and Baja Mexico, as well as the northern Channel Islands of California.
Occurrences Comments
The number of distinct occurrences is unknown but there are 290 accession records in the Consortium of California Herbaria database as of August 2007, and many of these records were collected since 1970.
Ecology & Habitat

Diagnostic Characteristics

Although some specimens of Cheilanthes clevelandii can be difficult to distinquish from C. covillei and C. intertexta, there is rarely a range overlap with these closely related species. Where C. clevelandii occurs with C. intertexta, the smaller spores of C. clevelandii separates the two species. Two varieties of C. clevelandii have been described but need further study (Flora of North America Editorial Committee 1993).
