In the water the most conspicuous plant was Eleocharis 
palustris rising to a height of one or two feet above the surface, 
and affording shelter to a flock of some forty or fifty wild ducks. 
E. acicularis was the only other sedge noticed, and grew per- 
haps more along the edge of the pond than in the water. Alis- 
ma Plantago and Sagittaria variabilis were both common, 
Potamogeton hybridus, not before noted in Montana, filled the 
water in places with a tangled mass, while a single plant of Masas 
flexilis was found near the shore, but a somewhat prolonged 
search failed to reveal a second specimen. Two species of Z/a- 
tine were abundant. &, Americana growing both on the muddy 
banks and submerged in the pond, and £. Cadlifornica, a western 
plant, only found submerged. This last has pedicelled flowers 
and much curved seeds. A few blossoms of Utricularia vulgaris 
rose out of the water, but the plants, which were common 
enough, were mostly not yet in bloom; also a few plants of the 
Herpestis above mentioned were found in several inches of water 
with leaves mostly floating and flowers emergent. The only 
other aquatic flowering plant recorded was Callitriche verna, 
growing very abundautly in some of the shallower places. 
A single moss was found mingled with the aquatic plants It 
was evidently a sterile, lax form of Hypnum fluitans, and was not 
common, 
The three remaining plants collected at this time belonged to 
the Characez and were submitted to Dr. T. F. Allen. He writes 
that they are of much interest, the species being Nitella clavata, 
N. opaca and Chara Altaica, this last not before credited to 
North America, and originally coming from the Altai Mountains 
of Asia. The species were all quite abundant, and bore well- 
developed fruit. They were mostly growing near the margin of 
the pond in two or three inches of water, and were quite strongly . 
attached to the mud of the bottom. 
In closing I would make grateful acknowledgment to Prof. 
D. C. Eaton for assistance in determining all the more difficult 
species when not otherwise stated.
