A NORTHERN VARIETY OF ERIGERON RAMOSUS. 
M. L. FERNALD and K. M. WIEGAND. 
For several years botanists collecting in the northern United States 
and Canada have been puzzled by a plant which seemed to be near 
Erigeron ramosus, as known farther south, but which in its sparser 
and more divergent pubescence often seemed referable to E. annuus. 
In studying the plants of western Newfoundland it was found that - 
there the only Erigeron of this group had these transitional characters, 
and in the absence of E. annuus from the island obviously could not 
be considered a hybrid between that species and E. ramosus. A recent 
study of all available material shows that this tendency of E. ramosus, 
with the foliage greener than in the ordinary plant and with the stem
