1924] Fernald,—Some Senecios of Eastern Quebec 119 
America. In the lobing of its leaves the type cf S. discoideus is like 
S. pauciflorus, but it has broadly deltoid instead of oblong cauline 
leaves and much more numerous heads than in the typical S. pauci- 
florus of Labrador and Quebec. Material from British Columbia 
closely approaches the Fort Franklin plant, however, and S. discoideus 
is best treated as an extreme development of S. pauciflorus. 
Greene's description of S. indecorus at once suggests the plant 
which has been passing as S. discoideus and a beautiful photograph of 
the type which has been generously furnished me by Professor George 
W. Albertson of the University of Notre Dame settles beyond question 
this identity. 
Briefly summarized the main characters and the bibliography of 
S. pauciflorus and S. indecorus are stated below, and a few character- 
istic specimens are cited.
