from the Gulf of St. Lawrence where A. parviflora was mistaken for it. In 
fact, on p. 192, Harshberger himself (by the use of symbols) states that A. 
narcissiflora does not occur in eastern North America.] 
“ Thalietrum alpinum L.” 
[Known from Arctic Alaska, thence south on the mountains to California, 
Nevada, and Utah; also in easternmost re on cliffs about the Gulf of 
St. Lawrence. Quite unknown from Ontari 
“ Ranunculus affinis R. Br. (= R. RE J. E. Smith).” 
[Surely not R. pedatifidus. "The plant of eastern Quebec which long passed 
as R. afinis is R. Allenii Robinson (see RuoporA, vii. 219-222), a species 
known only from Labrador and the highest mountains of eastern Quebec; 
not from Ontario]. 
“ Vesicaria arctica Rich. (= Lesquerella arctica DC. li. e. Watson]).” 
[Lesquerella arctica is known from Greenland and the Arctie coast of America, 
extending slightly southward on the outer coast of Labrador. It is entirely 
unknown in either Ontario or Quebec, but on Anticosti Island is represented 
by var. Purshii Watson, the plant Drummond undoubtedly had in mind.] 
“Cochlearia tradactylites Banks.” 
[Another aretie species, unknown south of Labrador, but formerly confused 
with C. anglica of the sea-cliffs of Anticosti and the Straits of Belle Isle.] 
“Cassiope (Andromeda) tetragona L. [i. e. (L.) Don].” 
[Another aretie type, extending south to northern Labrador and along ee 
mountains to Oregon, but unknown in either Ontario or Quebeec.] 
[p. 392] “ Dryas octopetala L.” 
[Known in America only from Arctic. Alaska south along the northern 
Rocky Mountains, but formerly not distinguished from the very different 
D. ee of ee the Gasp6 Peninsula, Newfoundland, Labrador, 
and Greenland. D. octopetala is quite unknown from eastern America.] 
5 a Ba Rich.” : 
[This unique species is abundant throughout the region of the Canadian 
Rocky Mountains, extending south into Montana; also on the limy river- 
gravels of Anticosti Island and the Gasp6 Peninsula, Quebee; and it has been 
reported from Slate Island, Lake Superior (see Macoun, Cat.). This dis- 
tribution, however, does not make it a characteristic woodland plant of the 
“Interlacustrine Area.” In fact, on page 190 we are informed that Dryas 
Drummondii is “found on the Rocky Mountains and the Gasp£ PEnınsuLa,” 
on p. 191 (the opposite page) that it is endemic in the Rocky Mountains, 
and on p. 392 it is made a woodland species “ common to Ontario and Quebee.”] 
These are a sufficient indication of the arctic-alpine plants which 
Harshberger considers to be common to the forest formation of Ontario 
and Quebec,— a list which could have been used in such a connection 
only through lack of familiarity with the “ Aedereieüne Area” 
and its flora.
