Do the genuses Arisaema and Disanthus belong to the same family?
Disanthus Disanthus is a genus containing two species of flowering plants in the family Hamamelidaceae. The type species, "Disanthus cercidifolius", was the only known species until 2017, when a second species, "Disanthus ovatifolius" was described.
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.
