SOME ANNUAL HALOPHYTIC ASTERS OF THE MARITIME 
PROVINCES.

(Plate 109.) 
WHEN the genus Aster was worked over for the seventh edition of 
Gray's Manual the three annual species included were noted as 
occurring on the marshes or saline sands of the lower River or the 
Gulf of St. Lawrence, two of the records based upon collections by 
the present writer, and one upon a specimen from Professor John 
Macoun. The three species, as then treated, were 4. subulatus Michx., 
the continuous northeastward range of which stops at the New Hamp- 
shire coast, but which is represented by a plant discovered in 1902 by 
Mr. Emile F. Williams and the writer on the saline shores of Nepisi- 
guit Bay, an arm of the Baie des Chaleurs in northeastern New Bruns- 
wick; 4. angustus (Lindl.) T. & G., a plant of the Great Plains of 
western North America and of salt plains of Siberia and Afghanistan, 
which has an isolated station on the shores of the St. Lawrence at 
Cacouna, Temiscouata Co., Quebec; and 4. frondosus (Nutt.) T. & G. 
of alkaline spots among the Rocky Mountains, with which was identi- 
fied a specimen collected in 1888 by Professor John Macoun at Brack- 
ley Point, Prince Edward Island, and sent to the Gray Herbarium as 
A. subulatus. 
During the summer of 1912, while botanizing about the Gulf of St. 
Lawrence, Messrs. Bayard Long, Harold St. John and the writer made 
a special point of collecting adequate material of the Prince Edward 
Island plant. It was found to be somewhat general in brackish sands
