EQUISETUM FLUVIATILE L. Supplementing Mr. Nel- 
son’s record of the occurrence of this species in Oregon, 
in the last number of the JourNAL, the following addi-

be mentioned: Lowlands along the Willamette River, 
five miles south of Corvallis, July 6, 1918. Walliam E.

LycopopiuM ALOPECUROIDES L. This species, men- 
tioned in a recent number of the JouRNAL? as one of the 
few likely to be added to the District of Columbia fern 
flora through further exploration in the coastal plain 
region east of Washington, was found by the writer, on 
September 26, 1919, in the magnolia bog near Suitland, 
Maryland, which Mr. Paul C. Standley has recently de- 
scribed? in connection with the local discovery of Senecio 
Crawfordii. The plant, which was not very abundant, 
was nearly confined to deep tussocks of sphagnum 
within a small area at the very wet lower border of the 
bog, in partial shade. Only a few individuals were fer- 
tile. The arched sterile stems were equally character- 
istic, however, offering the strongest contrast to the 
closely prostrate sterile parts of L. adpressum, which 
grew near by, rooting along their entire length. That
