Are Petrophytum and Townsendia both in the rose family?
Townsendia Townsendia is a genus of North American plants in the aster tribe within the daisy family.
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.
