The wildflower is a member of the flora in the rare quartz pebble plain habitat type on the north side of the lake, and of open meadows in the adjacent montane chaparral, pinyon-juniper woodland, and red fir forest habitats.<ref name=calfloradatabase/><ref name=calfloranet>[http://www.calflora.net/recentfieldtrips/pebbleplains12.html Calflora.net Blog: "Pebble Plains at Baldwin Lake Ecological Reserve" (with photo gallery)], by Michael L. Charters, April 2012.</ref> The diversity of Big Bear Valley Pebble Plains species has been compared to that of coral reefs, and include 17 protected plant species and four rare kinds of butterflies.<ref name=calfloranet/>

==Description== ''Linanthus killipii'' is a small annual herb producing a hairy stem from {{convert|5|-|15|cm|in}} tall. The leaves are divided into needle-like linear lobes each up to {{convert|1|cm|in}} in length.<ref name=jepson/>
