Mathiasella is a genus containing only 1 perennial species in the carrot family, Apiaceae, it is thus termed monotypic. The sole species, Mathiasella bupleuroides resembles Hellebore when flowering. It is a deciduous plant, native to Mexico, undiscovered until 1954. It was named in honour of the Californian plantswoman, Mildred Mathias. The species name 'bupleuroides' means it resembles the genus 'Bupleurum', but its umbeliferus flower heads with nodding bracts look more like that of a Hellebore.
How to propagate Mathiasella
Divide large clumps in spring. Plant divided clumps outside or pot up smaller divisions.
