Additions And Corrections To Madroño Paper
- Fred Roberts has kindly informed us that he knows of an additional about a dozen locations in Oceanside, Carlsbad, and Vista, all in northwest San Diego County, for B. filifolia. In Fig. 2A, this would form a chain along coastal San Diego County from the Orange County border to San Marcos. We will add those locations to the online plot when vouchers are available for our examination.
- Annette Winter's name was misspelled as Annette Winner; our apologies to her for our mistake.
- On 27 November 2007 we discovered that one population lives on basalt soil that might be derived only from the basalt of the Santiago Peak Volcanics instead of the Santa Rosa Basalt. If so, B. santarosae may be found on exposures of the Santiago Peak Volcanics elsewhere. Any such populations might outlast the Santa Rosa Basalt if the population size is large enough, and there continues to be suitable habitat on the Santiago Peak Volcanics.
