The new Locality for Subularia aquatica, L. 



By David F. Day. 



This plant, described by Linnaeus from Scandinavian speci- 

 mens, is probably to be found in all the northern portions of 

 Europe, including Great Britain and Ireland. Whether or not it 

 has been observed in northern Asia, I have, at present, no 

 means of determining ; but as plants of such high latitudes are 

 apt to be widely distributed, it probably may be found in Siberia 

 and Kamtchatka. As yet, however, it seems not to have been 

 noticed in Alaska. 



Its first discovery in America was by NuttalL Specimens 

 with his label, accrediting it to '* lakes in Maine/' are in several 

 herbaria. This was probably between 1830 and 1840. 



In 1844 Professor Tuckerman discovered the plant at **Echo 

 Lake, Franconia, N. H/' Some time later William Oakes also 

 found it there; and later still, after the failure of many botanists 

 to collect it, in September, 1882, it was rediscovered, in the same 

 locality, by Annie Trumbull Slosson. Her interesting account of 

 It may be read in the iith vol. of the BULLETIN, at page 118. 



A third American locality was found on the 13th September, 

 1882, by Professor Fletcher, at Vermilion Bay, Eagle Lake, C. P. 

 I^-, Dawson's Route. See Macoun's Catalogue of Canadian 

 Plants, Vol I, p. 55.

Since then it has been collected by Bolander, ''in pools in 



Mono Pass on the upper Tuolumne River/' in California, by Dr. 



Parry " at the head of Yellowstone Lake," by Professor Jones in 



Wyoming Territory, and by C. G. Pringle in Summit Lake, 



California, by Professor Jos, Schrenk at Squam Lake, New 



Hampshire, and by Professor Macoun at Sproat Lake, Van- 

 couver. 



To these localities Muskoka Lake, Ontario, must now be ad- 

 ded, as the tenth American station, where it was found on the 

 first of the current month. The precise spot was along a sandy 

 beach on the northeast side of Slater's Bay, near Port Sandfield. 



Probably in all the places, where it has been detected, it 

 grows abundantly ; but the localities are so widely scattered and 

 so far out of the lines of ordinary travel, that the species must still
