Yellow hackberry. A small-sized tree found along the bottoms of the larger 

 streams, and having a smooth trunk with warty pieces scattered over it. The 

 wood is of a beautiful yellow color and is quite soft and very easily split. As 1 

 understand the species it is found in Sutler, Cape Girardeau, Clay, Dunklin, Jack-

 Washington and Wayne counties. 



90. Celtis accidentalis putnila (Pursh) A. Gray. 



Low hackberry. A low shrubby species of hackberry, commonly considered as 

 a variety of the last, but I think it would be better to place it with Celtis Mississip- 

 piensis. It is found along rocky river banks, mostly in the southern part of the 

 State. It has been fonnd in Howell, McDonald, Newton, Oregon and St. Louis 

 counties. There is & Celtis in the southwestern part of the State that maybe a- 

 new species, but I have been unable to get sufficient material to determine this.

Paper mulberry. A fast-growing tree, commonly planted for shade in towns- 

 in the lowlands of the poutheastern part of the State. The soil and climate are so 

 congeniai;to its nature that it easily escapes from cultivation, and is found growing 

 in many places naturally. I have observed it only in Dunklin county. This tree i& 

 not quite hardy enough to stand the severe winter we have in Jackson county, but
