or in the region of the Gulf of St. Lawrence or in both areas. 
II. THE DWARF ANTENNARIAS OF NORTHEASTERN 
AMERICA. 
(Plate 142.) 
The larger species of Antennaria of temperate eastern America are 
reasonably understood, but there is another series of highly localized 
species, chiefly of the calcareous areas from northern Labrador to 
Newfoundland, eastern Quebec and the James Bay region, which 
have not been so clearly defined. These are the plants which have 
passed chiefly as A. alpina (L.) Gaertn. and which, with it, form a 
rather natural group of species. In the cordilleran region of North 
America these plants have attracted much attention and a large 
number have been proposed as species. In eastern America they 
occur wholly beyond the habitations of resident botanists, unless we 
include in eastern America botanically quite similar Greenland. The 
Antennarias of Greenland have been carefully treated and beautifully 
illustrated by Porsild;! but in the region immediately to the west 
and southwest of Greenland these plants are collected only by 
the chance botanical visitor and our knowledge of them, like 
our knowledge of the whole vast region from Gaspé and 
Newfoundland northward, is in very rudimentary condition. 
However, the necessity of properly identifying two quite distinct 
species discovered in 1923 on the Shickshock Mountains makes it 
desirable to draw into convenient form our knowledge to date of 
these plants. The following synopsis of the species occurring south 
of Hudson Straits is therefore presented, not because it is final but 
because it may draw attention to a group about which much more 
information is needed. Further exploration of Newfoundland, Anti- 
costi Island, the Gaspé Peninsula and the Labrador Peninsula will 
surely bring to light many additional species; and, to judge from our 
experience to date, they may be most hopefully looked for on barrens 
and mountains of limestone, basic schists and traps.
