Bissell; wet, sandy pond-margin, Sharon, September 7, 1909, C. A, 
Weatherby, no. 2,7313. New York: open alluvial and marshy flats 
between the city and Cayuga Lake west of the Inlet, Ithaca, August

Confused by Hitcheock & Chase with the more southern P. phila- 
delphicum from which it differs in habit, more leafy culm, short- 
exserted panicles, glabrous pulvini, and spicate-racemose branchlets 
of the inflorescence. Much nearer P. Gattingeri Nash, which, how- 
ever, has shorter and broader leaves, ellipsoid panicle, and more 
scattered, longer-pediceled larger spikelets. 
The type-sheet of P. Tuckermani was indicated by Tuckerman as a 
new species which he was afterward dissuaded from publishing. 
Tuckerman’s herbarium name, P. soboliferum, has twice been pub- 
lished in synonymy, first by Scribner & Merrill as a synonym of P. 
minimum in Ruopona, iii. 106 (1901), later by Hitchcock & Chase as 
a synonym of P. philadelphicum in Contrib. U. S. Nat. Herb. xv. 58 
(1910). In view of the fact that Tuckerman himself never published 
his herbarium-name and that it has twice been published by others in 
synonymy, it seems wisest to let it lapse and to use for the plant 
which Tuckerman at one time thought to be distinct a name which is 
open to no question and which at the same time associates the dis- 
coverer of the species definitely with the plant.

EropnEA. At Old Lyme, last summer, the writer was surprised to 
see an elodea growing abundantly in the brackish waters of a tidal 
stream, as he had known Elodea only in fresh waters. It was a plant 
with linear, acute leaves, quite different in appearance from the plant 
with firmer, more crowded, oblong, or ovate-oblong, obtuse leaves, 
which comprises much of the aggregate which has hitherto passed as 
E. canadensis, and is now segregated as Philotria canadensis (Michx.) 
Britton. Fortunately, a number of staminate flowers were found
