Tofieldiaceae
Sign in to saveTofieldiaceae is a family of flowering plants in the monocot order Alismatales. The family is divided into four genera, which together comprise 28 known species (Christenhusz & Byng 2016 ). They are small, herbaceous plants, mostly of arctic and subarctic regions, but a few extend further south, and one genus is endemic to northern South America and Florida. Tofieldia pusilla is sometimes grown as an ornamental.

Tofieldiaceae is a family of flowering plants in the monocot order Alismatales. The family is divided into four genera, which together comprise 28 known species (Christenhusz & Byng 2016 ). They are small, herbaceous plants, mostly of arctic and subarctic regions, but a few extend further south, and one genus is endemic to northern South America and Florida. Tofieldia pusilla is sometimes grown as an ornamental.
William Hudson (1730-1793) named Tofieldia for the British botanist Thomas Tofield (1730–1779). The family Tofieldiaceae was erected by Armen Takhtajan in 1995. Molecular phylogenetic studies of DNA sequences have shown it to be the second diverging clade in Alismatales, after the most basal clade, the family Araceae. Before the segregation of Tofieldiaceae was confirmed by cladistic methods, its genera had usually been assigned to Nartheciaceae, Liliaceae, or Melanthiaceae. Tofieldiaceae is recognized by the Angiosperm Phylogeny Group in their APG III system of plant classification.
