.... Arborea is most similar to Charniodiscus in construction, with both genera sharing an ovate petalodium attached to a stem and anchored to the substrate by a circular to bulbous holdfast. Arborea can be distinguished from Charniodiscus concentricus by the bifoliate petalodium and the smaller number...
