alfalfa and clover. In herbaria it is commonly labelled as (©. trifolii, a 
species that is now considered as being either synonymous with or at most 
but a variety of C. Hpithymum. It is also confused with C. pentagona be- 
cause of the fact that both species show a predilection for the same kind 
of hosts. This species has become very wide spread in North America hay- 
ing been found from the Atlantic to the Pacific and from Canada to Mexico. 
Its wide distribution is accounted for by the fact that its seeds are fre- 
quently found as a contaminant of those of leguminous crops. While col- 
lections of this species have been made in adjoining states none have been 
seen by the writer from Indiana.

This species, so far as known to the writer, has never been found in 
Indiana. It has been seen from Ohio and Michigan and is to be looked for 
wherever flax is grown. All of the specimens have been parasitic on flax. 
The private herbarium of Mr. Chas. C. Deam of Bluffton, Indiana, was 
the largest single collection of Indiana dodders seen by the writer. I desire 
to express my thanks for the loan of this and other collections which were 
sent me for study.
