the distribution in eastern America of the Skunk Currant (Ribes

CLASS II. WESTERN OR CANADIAN TYPES NOT REACH- 
ING LABRADOR. 27 species = 3} per cent of the Newfoundland 
Flora. 
These plants occur on the west side of the Gulf of St. Lawrence 
(in northern Nova Scotia, New Brunswick, the Gaspé Peninsula and 
adjacent area or on Anticosti) but are unknown in central and southern 
Nova Scotia, coastal Massachusetts, Long Island and eastern and 
southern New Jersey. From the following list, which includes all of 
the species of Class II, it will be seen that many of these plants are 
such as by further exploration are likely to be discovered in Labrador, 
when they will take their places in Class I; and that none of them 
are characteristic (if found at all) in the southern half of Nova Scotia 
and the coastal region southward.! Potamogeton filiformis, Trisetum

? Known as yet only from western Newfoundland and the upper Ottawa River (see 
p. 134). 
è There is a possibility that this was once found in eastern Massachusetts (see p. 130). 
+ Polygonum Roberti has been collected at the Grand Narrows, Cape Breton (Macoun, 
no. 20,206).
