Distribution: San Diego County, Riverside County, Los Angeles County, San Bernardino County, Inyo County, Kern County; Baja California, Mexico

Habitat: This small fern grows in shaded, rocky crevices in the desert mountains. Acid igneous rock lands are found at the Mountain Springs site. Observed sites were in partially shaded locales wedged between granitic fissures.

Known Sites: Sticky Lipfern grows near Mountain Springs in the shade of boulders near Myers Creek Bridge, and in Sentenac Canyon near the old bridge site. Herbarium specimens for San Diego County were examined from Upper Blair Valley, La Puerta, and Borrego Palm Canyon; from In-Koh-Pah Gorge in Imperial County; from Whitewater in San Bernardino County, on the north side of the San Jacinto Mountains in Riverside County; and from Surprise Canyon in the Panamint Mountains of Inyo County. It is reported by Munz from Twentynine Palms, the Granite Mountains near Victorville, and Darwin. Reported by Dedecker from the Argus, Black, and Kingston ranges. Reported by Twisselmann from Kern County on the east side of the mouth of Last Chance Canyon in the El Paso Range.

This fern is reported by Wiggins for the northern Sierra Juarez; however, no voucher specimens were found deposited at the herbarium of the San Diego Natural History Museum.

Status: Given the rugged, rocky desert foothills where this fern typically grows, it is presumed stable.
