Linnaeus. C. 1753: Species Plantarum. Impensis Laurentii Salvii, Stockholm.
Two spellings of the genus have been used: Hypochaeris and Hypochoeris. The name was published by Linnaeus in Species plantarum (Linnaeus 1753), as Hypochaeris. Linnaeus used Hypochoeris in Genera plantarum ed. 5 (Linnaeus 1754). However, he reverted to Hypochaeris in later works, such as later editions of Species plantarum.
Article 13.4 of the Code of Botanical Nomenclature (Greuter et al. 2000) explicitly states that "The spelling of the generic names included in Species plantarum, ed. 1 , is not to be altered because a diffrent spelling has been used in Genera plantarum, ed. 5 ". For "early" names the transliterations of the original authors must be retained (Article 60.7). It therefore seems quite clear that Hypochaeris is the correct name.
