Sebastopol Meadowfoam
Limnanthes vinculans
  
About Sebastopol Meadowfoam (Limnanthes vinculans) 0 Nurseries Carry This Plant Limnanthes vinculans, or Sebastopol meadowfoam, is an endangered species of meadowfoam found only in the Laguna de Santa Rosa in Sonoma County, California, USA 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). This species is only known from approximately 30 locations in the laguna de Santa Rosa and southern Cotati Valley of Sonoma County, in these areas it occurs in wet meadows and around vernal pools at elevations of under 300 meters. Sites range from Graton, around the northern and western perimeters of Sebastopol, and east to Santa Rosa. Like the other meadowfoams, Limnanthes vinculans is a small annual herb, with multiple stems growing up to 30 centimetres (12 inches) in height; white flowers occur singly at the ends of stems. This plant bears white flowers singly at the termini of its stems. L. vinculans is unique in its genus for having compound leaves with three to five leaflets; each leaflet is entire, with a narrow-obovate shape. The flowers are small (12 to18 millimeters across), white, generally bowl-shaped, and bloom in April and May. Although the young leaves are narrow and undivided, leaves on the mature plant have their undivided leaflets along each side of a long stalk (petiole). The shape of the leaves distinguishes Sebastopol meadowfoam from other members of the Limnanthes genus. The fruit consists of three to four millimeter long nutlets. Distribution and habitat.
