Number of Occurrences6 - 20

Rank Reasons

Cryptantha clokeyi is restricted to about 18 occurrences in southern California. It grows in Movajean desert scrub at elevations between 800 and 900 meters in elevation. Hickman (1993) reports that it is found on sandy or gravelly soils. It is considered potentially threatened by expansion of Ft. Irwin (DOD) (CNPS 2001).

Range Extent Comments

Southern California. Reported from Bare Mountains, Nevada.

Occurrences Comments

18 total EOs; 15 are recently surveyed.

Threat Impact Comments

Cryptantha clokeyi is considered potentially threatened by expansion of nearby Ft. Irwin (DOD) (CNPS 2001). Many CNDDB occurrences have no threats, but Silverman, 2010, states that military activities, OHVs and mining threaten some populations.
