Restricted to Santa Ana Mountains in Orange and Riverside counties, Iron Mountain in San Diego County and Baja California [1,2,3,4].
Within the MSPA two small conserved occurrences in MU8 (<500 individuals) in relatively close proximity (Wilderness Gardens and Mount Olympus Preserves; ).
Occurs in closed-cone coniferous forest, chaparral and cismontane woodland 550-1,370 m [1,3,4]. Associated with southern oak woodland forest with scattered Coulter pine and big cone spruce chaparral-oak woodland, and chamise chaparral. Soil conditions include Friant rocky fine sandy loams (Iron Mountain, San Diego County), Exchequer soils (Orange County), volcanic soils (Baja California; ).
In family Lamiaceae . One of five species of genus Lepechinia in California ; the five share traits indicating they derived from repeated instances of range expansion and contact among species with hybridization followed by range contraction and isolation of populations with subsequent differentiation resulting from drift and natural selection [1,7]. No species-specific studies regarding population genetics located. Members of the genus have a diploid chromosome (2n) number of 32 .
Flowers funnel-shaped, white to lavender-tinged in color . Calyx becomes scarlet purple and enlarges in fruit. Glaborous round to oblong fruit, one-seeded, 2-4 mm in diameter
Perennial shrub; blooms April-July .
