The genus Rehmannia includes six known species, all 
natives of China, though one—f. glutinosa, Libosch— 
extends also to Japan. It has given no little trouble to 
systematic workers, and one suggested species—R. ? Old- 
hami, Hemsl., a native of Formosa—has recently had to 
be transferred to Gesneraceae and treated as the type 
of a distinct genus. Three of the species have already 
been dealt with in this work. At t. 3653, under the 
synonym ff. chinensis, is given a figure of &. glutinosa; 
at t. 7191 2. rupestris, Hemsl., is depicted; at t. 8177, 
under the synonym R&R. angulata, a figure has been given 
of a species very nearly allied to A. angulata, which,
