Rank Reasons
Cryptantha incana is endemic to California and found in lower montane coniferous forest between 1430 and 2000 meters in elevation (CNPS 2001). Hickman (1993) indicates that it inhabits open, gravelly and rocky areas. There are 34 known occurrences but only three are surveyed recently. Threats are unknown 31 occurrences are historic occurrences. The rank is conservative and sensitive to the number of historic occurrences. Up to date survey information would likely impact the rank.
Range Extent Comments
Cryptantha incana is endemic to California and is known from Tulare, Fresno, Kern, and Inyo counties (CNDDB 2017).
Occurrences Comments
Thirty four occurrences but thirty-one are historic.
Threat Impact Comments
Threats are probably low but given the historic survey data from all but three occurrences threats are determined to be unknown.
