The Ranunculus^ Eritrichium^ Aster, Eupliorhia and Panica are not ex- 
clusively alkaline, and of these the first two are as often found in the moun- 
tains. Spergularia media was only collected at a salt spring in the Wahsatch 
and is added to complete the number of saline plants found, though not 
properly belonging in this list. The only shrubby or subshrubby species 
among them are the Grayia^ Halostachys^ Sarcobatus, Lycium, Kochia, and 
Suceda fruticosa. 
There is a very much larger number of species belonging to the second 
group, arpuatics or subaquatics, occupying the margins and banks of the lakes, 
springs and streams of purer water, or growing in the meadows or river 
bottoms in the near neighborhood of moisture — all properly fresh-water plants, 
though the localities in which they are found may often be to a considerable 
degree alkaline. Many of these are of course often found also on stream- 
banks in the canons, while others which belong to the mountain flora occasion- 
ally follow the streams into the valleys ; the first are indicated by (Mt.,) 
the last will be noted in the hst of mountain plants. As might be expected 
Ihoy are generally of very wide range. But five species can be considered 
peculiar to the Great Basin, all little known and in some cases questionable. 
Fifteen species extend only westward and eif^ht only eastward, while forty- 
three range from the Pacific slope toward the east, all but ten (R.) passing 
beyond the Rocky Mountains and nine approaching or crossing the arctic
