Limnanthes vinculans
''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''〔(Etymology for the expression ''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).
==Description==
Like the other meadowfoams, ''Limnanthes vinculans'' is a small annual herb, with multiple stems growing up to 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.〔(The Jepson Manual, University of California Press (1993) )〕
