Dielsia

Dielsia is a genus of flowering plant, described in 1904, in the family Restionaceae. There is only one known species, Dielsia stenostachya, endemic to Western Australia.

In 1929, Kudô used the name Dielsia in reference to a plant in the Lamiaceae, thus creating an illegitimate homonym. He also created one species in his genus, i.e.
 * Species in homonymic genus
 * Dielsia oreophila (Diels) Kudô, syn of Isodon oreophilus (Diels) A.J.Paton & Ryding
