Mathiasella

Mathiasella is a monotypic genus of flowering plants belonging to the family Apiaceae. It is in the Tribe Selineae. The genus only contains one known species, Mathiasella bupleuroides Constance & C.L.Hitchc.

It is native to Mexico.

The genus name of Mathiasella is in honour of Mildred Esther Mathias (1906–1995), an American botanist and college professor and also Director of the UCLA Botanic garden. The Latin specific epithet of bupleuroides means "like Bupleurum" in recognition that it has visual similarities to Bupleurum, another genus of plants in the Apiaceae family, that has worldwide distribution. Both the genus and the species were first described and published in Amer. J. Bot. Vol.41 on page 56 in 1954.
