CALLITRICHE AUSTINI IN SOUTHWESTERN CON- 
NECTICUT. 
E. H. Eames, M. D. 
THE interesting but decidedly inconspicuous Callitriche Austini 
Engelm. is found sparingly within a few miles of New Haven (Or- 
ange), thence westward, usually in small quantities and at infrequent 
intervals, fully twenty miles. In Fairfield there are several colonies 
covering from one to three square rods, approximately. 
It seems to prefer the damp earth of little used cart-paths or old 
roads, in woods or partial shade along their borders, and but little 
elevated above adjoining, or at least not distant, salt marshes. Oc- 
casionally it is so situated that every heavy rain will submerge it for 
a time, but the ensuing mud, while not at all unfavorable to the 
growth of the plant, soon settles to a moderate degree of moisture. 
From its habit of hugging the earth in such places, it is not rarely 
covered with mud during the subsidence of turbid waters, although its 
growth is not materially affected thereby. 
Search for it in early June has usually been disappointing, whereas, 
by July 1 it may be seen in flower sparingly, and all through the 
month in increased quantity. Fully mature dull black fruit may be 
found in the middle of the month, while a few days more suffice for 
an abundance of it; even well into August, in most favorable situa- 
tions, it still clings to the crumbling or decaying stems. 
The height of its season seems to be the last two weeks of July, or 
until the burning heat of midsummer. At that time it might be
