Extension of range of downy poplar 
FRED R. CLARK 
The writer wishes to report an extension of the range of the 
downy poplar, Populus heterophylla L. A good sized specimen of 
this tree was found growing in a swamp about three miles south- 
west of the city of Ann Arbor, Michigan. This specimen was 
approximately thirty-five feet in height and measured about 
eight inches in diameter, breast high. It was well developed in 
every way as far as could be observed. Attention was first called 
to it by one of the writer’s students who was attracted by the 
large, downy leaves scattered over the ground. After careful 
examination the species was determined to be Populus hetero- 
bhylla L. As far as the writer can find out from a search of the 
literature this tree has been reported from the state only once 
before, namely from Cass County by J. H. Roy.* Gray’s 
Manual gives the range as “Borders of river swamps, Ct. to 
Ga.; also from O. to Ark. and La.” It is not listed in Otis’ 
“Michigan Trees,” but is recorded in Deam’s “Trees of Indiana” 
as growing in swamps in the northern counties of Indiana. It is 
likely that the tree could be found growing in other parts of 
Michigan if careful search were made for it.
