Southern Skullcap [Scutellaria bolanderi Gray ssp. austromontanum Epling]

Listing CNPS List 1B R-E-D Code 2-2-3

State/Federal. Status -- None LAMIACEAE Jun.-Aug.

Global Rank G?T2T3 State Rank S2?

Distribution: San Diego County, Riverside County, San Bernardino County

Habitat: The Southern Skullcap is a small herb typically growing on the moist embankments of montane creeks. At Pine Valley the soils are mapped as Riverwash, there is little canopy cover, and it occurs with a diverse assemblage of facultative wetland annuals and herbaceous perennials.

Known Sites: This species is lightly distributed in Pine Valley Creek near the Noble Canyon trailhead. Herbarium specimens are from 0.25 mile north of Green Valley Fire Road, at Viejas, below Cuyamaca Lake, at Japatul Valley near the school, on Witch Creek, Fry Creek, French Valley, Doane Creek, and at the Palomar Observatory Road in a meadow. It is also reported from Lake Henshaw and at Morena. In western Riverside County is reported from the head of Cole Canyon near the Santa Rosa Plateau, on Strawberry Creek 2 miles southwest of Idyllwild, and in the upper May Valley/Hurkey Creek area. Munz reports this species in Victorville. No collections for Baja California could be located.

Status: More collection information is needed about the distribution and population numbers of this species. It is presumed stable within the Peninsular Range portion of its habitat; but such an assessment needs further verification. In the mountains of San Diego County Southern Skullcap is potentially impacted by increases in recreational activities. All populations should be protected.
