Abstract

In an effort to further resolve relationships within the genus Limnanthes and the family Limnanthaceae a phylogenetic study was conducted using one nuclear (nrITS) and two chloroplast (trnL intron and trnS-trnG intergenic spacer) genes In addition to surveying all currently accepted taxa within Limnanthaceae, an anomalous population of 4-petalous plants from Half Moon Bay, San Mateo County, California, was also included Further, a series of crossing experiments were performed between Half Moon Bay plants and two closely related species (Limmanthes bakeri and L macounu) The results of this study confirm the monophyly of two sections within Lmmanthes and also suggest that Limnanthaceae may contain as few as four species of Lminanthes and the monotypic genus Flocrkea proserpinacoldes Additionally, the molecular phylogenetic results and crossing experiments do not support taxonomic recognition of the Half Moon Bay population, rather it is part of a highly polymorphic Limnanthes douglasn sensu lato
