ST. JOHN: SABLE ISLAND. 65 
J. Macomi (C. nos. 77,185, 77,186, 77,103, 22,648); H. T. Giissow; 
II. St. John, no. 1,152 (H). 
Fl. — August. 
E. palustris (L.) R. & S., var. glaucescens (Wllki.) Gray. Even 
more common than the preceding, but found sprawHng on the drier 
sand flats or in nearly bare dune hollows. J. Macoun (C. nos. 22,640, 
22,647, and 77,187); //. ^7. Johv, nos. 1,153, 1,154, and 1,155 (H). 
Fl. — August. Fr. — August and September. 
Scirpus nanus Spreng. Found only by the brackish margins of 
Wallace Lake. J. Maeoim (C. no. 22,649); //. T. Giissow; II. St. 
John, no. 1,156 (H). 
Fl., Fr. — September. 
S. americanus Pers. Common in the dune hollows. J. Macoun 
(C. no. 22,632); //. T. Giissow; II. St. John, no. 1,157 (H). 
Fl. — August. 
S. acutus Mulil. (S. occidcntalis (Wats.) Chase.) Brackish and 
nearly fresh ponds near Wallace Lake. Some of the specimens have 
been named S. valiJus but none seems to belong in that species. ./. 
Macoun (C. no. 22,633) is very young material. //. T. Giissow's 
collection has well developed achenes only 2 mm. long, but the spike- 
lets are borne for the most part in glomerules, so the plant is treated 
as of this species. //. St. John, nos. 1,1 5S and 1,159 (H) do not have 
long spikelets, but the achenes are large, 2.5 mm. long, and the 
scales are long and overlapping. These specimens with a mingling 
of characters of S. validtis and of <S. acutiifi raise the question as to 
the distinctness of these two species. 
Fr. — September. 
[S. occiDENTALis (Wats.) Cluisc is S. acutus.]
