EXPLANATION OF PLATES ILLUSTRATING AZOREAN PLANTS. 
The plates were drawn by Miss Grace E. Johnson, under 
supervision of the author. Most of the enlarged details 
are after studies by Mr. J. B. S. Norton. The inten- 
tion has been, where possible, to figure each species not 
yet figured or the illustrations of which are not readily 
accessible.
