In the present work, a few species are mentioned under

There are three species which are properly transferred from one 
family to another. One is a plant which was called Rehmannia 
Oldhami Hemsu, formerly referred to Scrophularineex, but now 
to Gesneraces. The reference to the species is given under

regard it as representing a distinct genus from Rehmannia. He 
then established a new genus, Matswmuria,” for the plant, and
