Taxonomic CommentsThe distinctiveness of this taxon is in question and it is sometimes treated as P. perityloides var. jaegeri (Hickman 1993, Baldwin et al. 2012), however, it is treated as a species by Walden and Patterson (2012).

Rank ReasonsLittle is known about Phacelia geraniifolia or referred to as P. peritiyloides var. jaegeri in California. It occurs in Clark Co., Nevada in the Sheep Mountains and in California from Clark Mountain. During the 2003 Nevada Rare Plant Workshop it was left open for discussion and for further review as to whether to add this species to the state's Fully Protected Native Flora list. No specific information about threats was found during the 2015 conservation status review, however, given that it occurs in Clark Co., Nevada it could experience indirect threats from Las Vegas.
Range Extent CommentsIn California, this taxon is only known from Clark Mountain and is more plentiful in the nearby Sheep Mountains in Clark Co. in Nevada. It is expected to occur in other areas where favorable conditions exist (CNPS 2015). The Nevada Rare Plant Workshop held in 2002 reported that this species is fairly common in Red Rock Canyon National Conservation Area, and is also known from fewer than a dozen populations from the Potosi Mountain to La Madre Mountain, Nevada (NVRPW 2003).
Threat Impact CommentsGiven that this species occurs in Clark Co., Nevada it may be threatened by development or indirect effects like pollution, from Las Vegas, but notes from the 2003 Nevada Rare Plant Workshop didn't site specific threats.
Ecology & Habitat
Habitat
Dry rocky habitats, usually with carbonate substrate, including cliff crevices, rock crevices, rock walls, and rocky slopes. Found predominantly within Pinyon-Juniper Woodland communities, including pinyon-littleleaf mountain-mahogany and sagebrush-pinyon-juniper assemblages; also found within ponderosa-white fir communities. In Nevada, co-occurring species include Ericameria sp. and Larrea sp. 800 - 2440 m.
