Vars. alpestre and pungens seem to be the alpine and boreal extremes 
of the two woodland plants of more temperate habitats, true L. anno- 
tinum and var. acrifolium. It is specially noteworthy, therefore, that 
the flat- and broad-leaved var. alpestre of northern Europe should 
have been found in North America only at the northwestern edge of 
the continent, although in the East the flat- and broad-leaved typical 
woodland L. annotinum abounds. It is also noteworthy that the two 
plants with firm rigid entire and acerose-attenuate leaves, vars. 
acrifolium and pungens, widely distributed in northeastern America, 
should be unknown from western North America and rare or unknown 
in Europe, but both present in northern Asia. The ranges of these 
varieties thus fall essentially into the definite groupings — Europe 
and western America, eastern America and Asia — already familiar 
in hundreds of other cases.

ANTENNARIA CANADENSIS IN PENNSYLVANIA. 
Hanorp W. PRETZ. 
In his article, entitled “Southerly Range Extensions in Anten- 
naria,” ? Mr. Bayard Long makes the following statement: “ Although 
Antennaria canadensis has not yet, to the best of my knowledge, 
been collected between the Catskills and Natural Bridge, I feel that 
1 Luerssen does not recognize var. alpestre, and it is probable that the plant of 
the Tyrol referred by him to the American var. pungens may prove to be the 
European var. alpestre.
