California Bluebells Along the Gabrielino Trail

California bluebell (Phacelia minor)

Like Turricula (Poodle-dog bush)*, California bluebell (Phacelia minor) has been shown to cause a contact dermatitis similar to poison oak. The results from one study suggest the “dermatotoxic potential” of California bluebell approaches that of poison ivy/oak and that it is more likely to produce a reaction than Turricula.

Fortunately California bluebell doesn’t appear to be as prolific a fire follower as Turricula and is a much smaller plant.

The photograph is from a trail run in May.

*The taxonomic name for Turricula parryi (Poodle-dog bush) has changed to Eriodictyon parryi. The Jepson Manual: Vascular Plants of California, Second Edition (2012) has returned Turricula to the genus Eriodictyon, as originally described by Gray. According to the Wikipedia entry for Turricula (April 11, 2012), “… molecular phylogenetic analysis carried out by Ferguson (1998) confirms that Turricula should be treated as a separate genus within a clade (Ferguson does not use the term “subfamily”) that includes Eriodictyon, and also the genera Nama and Wigandia; Eriodictyon is the genus to which Turricula is closest in molecular terms, and is its sister taxon.” I use “Turricula” and “Poodle-dog bush” interchangeably as a common name.
