Oksanhaaraisia
Oksanhaaraisia is a genus within the family Oksanhariaceae, described in 1978 by botanist L. J. Tamm. The name derives from the genus Oksanha, an indigenous word meaning "branching flower", combined with the Latin suffix –ia denoting a group. The genus is currently represented by three recognized species: Oksanhaaraisia arboris, Oksanhaaraisia florida, and Oksanhaaraisia graminea. All species are herbaceous perennials found primarily in temperate regions of East Asia, with sporadic reports in the Alps and certain parts of Canada.
Morphologically, members of the genus possess simple, alternate leaves, typically lanceolate to ovate, with serrated margins.
Ecologically, Oksanhaaraisia occupies moist, open woodlands and meadow edges, often in calcareous soils. These plants play
