Do Waldsteinia and Obregonia contain the same number of species?
Waldsteinia Waldsteinia, the barren strawberries, is a genus of the rose family (Rosaceae). It contains about six species native to the temperate Northern Hemisphere. A number of species are cultivated as a ground cover in gardens, including "Waldsteinia fragarioides" from North America, "Waldsteinia geoides" from Europe, "Waldsteinia lobata", and "Waldsteinia ternata" from Eurasia (from Central Europe to Siberia, China, and Japan).
Olmediella Olmediella is a monotypic genus of flowering plants in the willow family, Salicaceae. It consists of one species of trees: Olmediella betschleriana, which is native to Central America. Formerly placed in the heterogeneous family Flacourtiaceae, "Olmediella" is now classified in Salicaceae, along with close relatives "Bennettiodendron", "Carrierea", "Idesia", "Itoa", "Macrohasseltia", "Poliothyrsis", and even the willows ("Salix") and cottonwoods ("Populus") themselves.
