Latouchea is a monotypic genus of flowering plants belonging to the family Gentianaceae.

[2] The genus name of Latouchea is in honour of John David Digues La Touche (1861–1935) an Irish ornithologist, naturalist, and zoologist as well as his wife, who both collected botanical specimens.

[3][4] The specific epithet of fokienensis resembles the maiden name of La Touche's wife, née Caroline Dawson Focken (1871–1945).

However Fokien is a historical name for the Fujian region of China, and the -ensis denotes being "of/from a place".

For honorific species names involving people, in contrast.
