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).
Woodwardia areolata Woodwardia areolata, the netted chain fern, is a species of fern native to eastern North America. It is usually treated in the genus "Woodwardia", in the eupolypods II clade of the order Polypodiales, in the class Polypodiopsida. It is sometimes transferred to the monotypic genus "Lorinseria" as "Lorinseria areolata" (L.) C.Presl, on the basis of its anastamosing veins and lobed frond form, as well as its more marked frond dimorphism; however, the genus name "Lorinseria" is invalid, being an orthographical variant of "Lorinsera" Opiz ("Flora of North America").
