of the “North Shore,” i. e. the outer or Gulf shore of the island, at 
least from Tignish to Grand Tracadie, while a seemingly identical 
plant was found on brackish shores at Étang du Nord, at the southern 
end of Grindstone Island in the Magdalen Island group; and a closely 
related but obviously distinct plant was found in great profusion cover- 
ing the damp brackish sands at Grande Entrée near the northern end 
of the Magdalen Islands. 
Upon critically studying this material it was quickly apparent 
that the Prince Edward Island plant, which had been originally dis- 
tributed as Aster subulatus and subsequently referred to A. frondosus, 
could have no specific connection with either, for it has quite rayless 
heads like those of the unique A. angustus, and in its very foliaceous 
involucre it is unlike any described species. It was also apparent 
that the little plant so abundant at the northern end of the Magdalen 
Islands differed in some pronounced varietal characteristics from the 
plant of Grindstone Island and of Prince Edward Island. 
In the course of this study of the annual Asters from Prince Edward 
Island and the Magdalen Islands, the plant from northeastern New 
Brunswick, which had been referred to A. subulatus, was also reexam- 
ined and found to differ in certain important points from the plant 
of our Atlantic coast. It was consequently gratifying that, in his 
explorations of the coastal sands of eastern New Brunswick during 
the late summer and autumn of 1913, Mr. Sidney F. Blake was able 
to secure a collection of mature material of the so-called A. subulatus 
from the shores of Nepisiguit Bay and thus to reinforce the characters 
already noted in the rather immature material of Williams & Fernald. 
And it was especially interesting that, upon the marshes of the Tra- 
cadie Lagoon of northeastern New Brunswick, Mr. Blake should also 
find a third area of the little rayless species already known from the 
islands in the Gulf; but the most notable point about the plant of the 
Tracadie Lagoon is that, while clearly belonging specifically with the 
others, it should show in its foliage and involucres characters almost 
exactly intermediate between the plant of the Prince Edward Island 
sands and the extreme variety which covers the sands of Grande 
Entrée, near the northern end of the Magdalen Islands. 
The third species of this remarkable group of annual Asters of the 
St. Lawrence shores, the plant identified with Aster angustus, has not, 
. so far as the writer is aware, been collected since he and Professor J. F. 
Collins found over-ripe material at the border of a salt marsh at Ca-
