Samolus (known as brookweed, or water pimpernel) is a widely distributed genus of about a dozen species of water-loving herbs and amphibious flowering plants. According to the APG III system of classification, the genus falls within the primrose family, Primulaceae, under the order containing the rhododendroid eudicots, Ericales. It was considered closely related to a clade comprising the Theophrastaceae,{{cite journal |doi=10.3732/ajb.91.5.627 |vauthors=Caris PL, Smets EF|title=A floral ontogenetic study on the sister group relationship between the genus Samolus (Primulaceae) and the Theophrastaceae | journal=American Journal of Botany |volume=91 |year=2004 |pages=627–643 |issue=5 |pmid=21653418|doi-access=free }} and was likewise treated as part of that family (or its own monogeneric family, the Samolaceae). The APG III system does not recognize these families, instead classifying all former Theophrastaceae genera within the family Primulaceae.

Although some local floras recognize the North-American populations of S. valerandi as a separate species (S. parviflorus) or subspecies (S. valerandi ssp. parviflorus),{{cite web |title=Samolus |work=Flora of North America |url=http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=129104 |publisher=eFloras.org |access-date=2018-02-01}} molecular and morphological data indicate that S. vagans and S. parviflorus should not be regarded as separate species but as part of a widespread "S. valerandi species complex.{{cite journal|last1=Jones|first1=K.|last2=Anderberg|first2=A.
