stems, of the section Euequisetum, which was unfamiliar 
to both of us. This delta, formed by the entrance of 
a considerable mountain-stream from the melting 
snows in Hunt’s Cove, occupied an area of perhaps five 
acres, making a vivid patch of dark green in the rather 
arid region surrounding it. The Equisetums averaged 
about 10 dm. in height, naked below, with 5 to 10 whorls 
of rather long flexuous branches above, and covered 
the ground as closely as wheat in a grain-field. The 
only associates that we observed were Carex sitchensis, 
Calamagrostis canadensis and Cinna latifolia, none of 
which were at all frequent. 
An examination of the specimens that I brought 
home led me to the conclusion that the plant was 
E. flwiatile L—a determination kindly confirmed by 
Professor L. S. Hopkins. This is a species of very 
wide range both in North America and Eurasia, al- 
though not to my knowledge previously collected in 
Oregon. The range for the Pacific Coast given by 
Piper in his Flora of Washington (p. 86. 1906) is “Alaska 
to Washington.” Henry in his Flora of Southern British 
Columbia (p. 9. 1915) gives it as “Alaska to Oregon,” 
but cites no specimens to confirm it. The herbarium 
of the University of Oregon contains no specimen from 
the Pacific slope. The fact that this is its first oceur-— 
rence in five years of assiduous collecting shows that it is _ 
at least not frequent here. 
Of the plants observed, not above one in fifty bore the 
fruiting cone, the apex of the others being wholly sterile. 
The “freak” specimen, to which our attention was 
specially directed, may be briefly described as follows: 
otal height of stem, 8 dm., naked for 5.3 dm. 
above the base, then 7 whorls of branches and a normal 
strobile at the apex. The uppermost whorl was com- 
posed of 16 branches, the longest measuring 8.5 em. 
Fifteen of these branches bere strobiles at the tip,
