I have observed the true Carolina poplar * P. angulata” in its native 
region along the Savannah River opposite Augusta, Ga. 
Since Michaux, Jr. recorded the species from the Lower Virginia 
we are justified in discussing it in this paper. 
It is difficult to interpret the few lines of description given by 
Marshall ! of his “ Populus deltoide." The description of the leaves 
might fit any one of the forms now grouped under * P. deltoides.”

But his statement “It grows naturally upon rich low lands, onthe 
banks of large rivers in Carolina and Florida” would compel us to 
apply the name to P. angulata Ait., if we could be sure of its being the 
only species of the Aigeiros group in the South. In my own treat- 
ment of the black poplars I have applied the name P. deltoides to the 
tree which the Philadelphia botanists of a century or more ago were 
wont to see in their native region. Marshall (l. c.) mentions also P. 
nigra, the black poplar. His description of this tree would indicate 
that he had the true P. nigra in hand for he states that the leaves of 
it are “a little downy underneath," a condition which does not exist
