Trees and Shrubs of Kern County (Jan 2013)

Zauschneria californica C. Presl 1831 [Epilobium canum (Zauschneria cana Greene 1887) Raven 1977]. Humming bird fuchsia. Subshrub with shredding epidermis of stem-bark; flowering Aug–Oct, flowers scarlet, long tubular, much like Fuchsia.  Rock walls of canyons, or open rocky slopes bordering streams, below3,500 ft.  Type from Monterey, CA. Kern Co.: Occasional from the woody cismontane Upper Sonoran associations to the lower levels of the yellow pine forest in the mountains and the Temblor Range, usually growing around rocks (Twisselmann).  CCH: Tillie Creek Campground near Lake Isabella, Kern River Canyon, Grapevine Creek in the Tehachapi Mts.,  and below turnoff to Valle Vista Campground in the Temblor Range, 457–610 m.

The Jepson manuals have included Z. californica in Epilobium (JM1: Wagner, Raven, Hock. JM2: Wagner & Hock), which its species seem to consistently differ in the spreading of the petal lobes, and in the flower color not scarlet but pale rose to white.  Wagner, Hoch & Raven (2007, Syst. Bot. Mongr. #83)), in their “Revised Classification of the Onagraceae,” stated that “Section Zauschneria is extremely distinctive by virtue of its long tubular orange-red zygomorphic flowers, which are pollinated by hummingbirds; historically it has been maintained as separate genus related to but quite distinct from Epilobium,” followed by references to molecular studies that reported 75–97% support for clades including section Zauschneria.

The related Z. latifolia Greene 1887, with subspecies status in JM2, is distinguished by the herbaceous habit and wider leaves (>6 mm); it is more common in the County, 884–2,072 m (CCH).
