In the Flora of the Mayacmas Mtns., Neilson cited the following location: 1/4 mile south of Geyser Peak (which is in Sonoma County). The notes on the specimen itself say: western portion of Geyser Rock, western Lake County (he must have meant eastern portion of Geyser Rock, or he would have been in Sonoma County). As all his other specimens from this date were collected in western Lake County east of Geyser Rock, we are using that location. (Coordinates and elevation estimated by label maker.) 1089 Comment
