“ A great many districts are burned over in the fall, but I 
think it is only the fires that take place after growth has com- 
menced in the spring that produce this result.”

This paper is supplementary to Mr. L. F. Ward’s “ Guide to 
the Flora of Washington,” and contains the additional Phanero- 
gamia and Pteridophyta detected in the region up to April 1, 
1886, 39 in number. 
Rev. E. Lehnert contributes “A Revision of the Musci

to species published in Mr. Ward’s Guide are noted; new sta- 
tions for rare species are recorded, and a few corrections to 
previously published lists are made.”

It appears that four species of fungi are principally con- 
cerned as vine pests in this country. These are the Downy Mil-

ula spiralis, B. & C.), the Black Rot (Physalospora Bidwelli, 
Sac.), and Anthracnose (Sphaceloma ampelinum, De By.). These 
are all carefully described and beautifully illustrated. The 
Downy Mildew is found both on our wild and cultivated grapes, 
and has doubtless been conveyed from the former to the latter. 
The Powdery Mildew is also a native of America, and attacks 
both wild and cultivated vines, showing a preference for those of 
the Vinifera class. The Black Rot is likewise of American ori-
