Do Schomburgkia and Cynoglossum belong to the same family?
Cynoglossum There are many species in the plant genus Cynoglossum ( ). They are coarse-appearing, small-flowered plants of the family Boraginaceae. "Cynoglossum officinale", the common hound's-tongue, is a native of Asia, Africa, and Europe. It has been introduced into North America, and it is considered to be a troublesome weed because its burs stick to the wool of sheep and to other animals. Ingestion of this plant can also lead to photosensitivity in grazing animals.
Cyrtomium Cyrtomium is a genus of about 15-20 species of ferns in the family Dryopteridaceae, native to Asia, Africa (including Madagascar), and the Pacific Ocean islands (Hawaii). It is very closely related to the genus "Polystichum", with recent research suggesting it should be included within it (Little & Barrington).
