are Cladanthus and Oxydendrum both plant genus ?
Cladanthus Cladanthus is a genus of plants in the family sunflower family, native to the Mediterranean region.
Adiantaceae Adiantaceae (as construed here, "sensu stricto", not a synonym of Pteridaceae) is a family of ferns in the order Pteridales. This includes the family formerly known as the "Vittariaceae." Recent genetic analyses based on chloroplast genes demonstrate that the vittarioid ferns cladistically nest within the genus "Adiantum", making that genus paraphyletic.
