bloom till September, or even October. One more plant of this 
family, and perhaps the most curious and interesting of them all, 
was Evax prolifera, growing in low places where the grass was 
thin or altogether wanting. In many respects it resembles the 
Edelweis of the Alps, although its home and surroundings are so 
exceedingly humble as compared with that celebrated plant. 
Dead specimens of the Evax were very numerous in places, and 
resembled, more than anything else, small, blackish tufts of up- 
turned fiberous roots. The stems and branches of the growing 
plants, indeed, are stiff and wiry, and would hardly be noticed 
were it not for the curious heads of woolly flowers they bear. 
In about the same situations as the above, Herpestis rotundt- 
Jolia was found abundantly both in flower and fruit. The range 
of this is given in the last edition of Gray’s Manual as “ Illinois 
to Minnesota, Missouri and southward,” but in the Synoptical 
Flora of North America it is referred to as growing out of ordi- 
naty range in Fresno Co., California, and it evidently may prove 
to be more of a western plant than has heretofore been supposed. 
The corollas of the plants in the present case were perfectly white, 
with Jobes just about equal and stamens of equal length. I called 
the attention of Prof. Eaton to these points, and he writes that 
he has evidently the same plant from Illinois, collected by Les-_ 
quereux, who notes, “corolla white, almost equally five-cleft.” 
Possibly the normal color of the flower is white, although the 
botanies till recently have mostly given it as blue. 
Other plants growing about the pond were Limosella aqua- 
“ica, very abundant and often submerged in the water, Rumex ‘ 
Salicifolius, Verbena bracteosa, CEnothera triloba, a common but 
inconspicuous species, AKrynitzkia Californica, Boisduvallia gla- 
bella, abundant along the very edge of the pond, anc Gilta inter- 
texta, of which only a specimen or two was observed. These 
last two mentioned species are well-known western plants that 
here in Montana, at least, cross to the eastern slope of the Rocky 
Mountains, 
The above about completes the list of species noted around 
the margin of the pond, and it will be observed does not include 
ashrub or tree of any kind. Doubtless rose bushes of stunted 
Srowth existed, but were overlooked at this season.
