tofieldia

A few authors have sunk other genera into Tofieldia as well.

Many authors do not recognize Triantha as a separate genus from Tofieldia.

Some authors have included Triantha within the genus Tofieldia.

Triantha is distinguished from Tofieldia by its glandular-pubescent stems and by the presence of seed appendages.

Scottish Asphodel (Tofieldia pusilla)

In his honour, Gmelin named a plant Hebelia allemannica, though it was later renamed Tofieldia calyculata.

Tofieldia pusilla is a flowering plant of the genus Tofieldia in the family Tofieldiaceae.

In 2011, a study of two nuclear genes and ten chloroplast genes showed that Triantha and Tofieldia are monophyletic and closely related sister clades.

A phylogenetic analysis, based on two nuclear genes and ten chloroplast genes, has confirmed that all five of the genera are monophyletic and that Triantha and Tofieldia are close sisters.

However, the original description of Isidrogalvia proved to include a European species previously used (under a different name) to typify Tofieldia, thus inadvertently rendering Isidrogalvia a later synonym of Tofieldia.

Associated plant species include Oclemena nemoralis, Calamagrostis pickeringii, Calamovilfa brevipilis, Juncus caesariensis, Lophiola americana, Muhlenbergia torreyana, Platanthera integra, Pogonia ophioglossoides, Rhynchospora oligantha, Schizaea pusilla, and Tofieldia racemosa.
