PHjakaumia is a genus of extinct flowering plants known from fossil material that includes leaf impressions and pollen grains. It is considered monotypic, containing the species PHjakaumia mirabilis. The genus is documented from Paleogene assemblages in North America and Europe, with material dating to the early to middle Eocene. The etymology of the name is not clearly recorded in primary literature, and it is treated as a constructed taxon name.
Discovery and naming of PHjakaumia occurred within the context of studies on Eocene floras, where distinctive
Morphology is typical for a small, herbaceous to subshrubs-like plant. Leaves are palmately to deeply lobed,
Distribution and ecology indicate that PHjakaumia inhabited temperate to subtropical forest ecosystems of the early Eocene,
Taxonomy and research status remains unsettled. Some classifications have proposed a separate family, PHjakaumiaceae, for the
