Limnanthes vinculans Limnanthes vinculans, the Sebastopol meadowfoam, is an endangered species of meadowfoam found only in the Laguna de Santa Rosa in Sonoma County, California, United States and an area slightly to the south in the Americano Creek and Washoe Creek watersheds. The name "vinculans" derives from the Latin root vinculum, meaning "a bond, a cord." The specific epithet "vinculans" means linking or bonding, in reference to the sharing of some characters of "L. vinculans" with "L. douglasii" (R.Br) and "L. bakeri" (J.T. Howell).
