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.
