Aremonia is a monotypic genus of flowering plants in the rose family (Rosaceae), order Rosales. It contains a single species, Aremonia agrimonoides (Bastard-agrimony), a herbaceous perennial that closely resembles the true agrimonies of the related genus Agrimonia, from which it is distinguished by subtle morphological differences in the hypanthium and fruit structure. The genus belongs to the subtribe Agrimoniinae within the family Rosaceae.
Aremonia agrimonoides is native to central and southeastern Europe, extending eastward to Türkiye, where it grows in woodland margins, shaded slopes, and montane habitats. Because the genus is monotypic — containing only this one species — all taxonomic and ecological information concerning Aremonia refers directly to A. agrimonoides.
Etymology
The genus name Aremonia is derived from its resemblance to Agrimonia (true agrimony); the common name "bastard-agrimony" reflects this close but distinct relationship within the subtribe Agrimoniinae.
Distribution
Aremonia agrimonoides, the sole species in the genus, is native to central and southeastern Europe, ranging east to Türkiye. It typically grows in shaded forest margins and montane woodland habitats across this range.
Taxonomy Notes
Aremonia is a monotypic genus placed in subfamily Rosoideae, tribe Sanguisorbeae, subtribe Agrimoniinae within Rosaceae, making it a close relative of Agrimonia (true agrimonies). GBIF records the genus as accepted with three infraspecific taxa beneath the single species A. agrimonoides.
