866 REPORT OF STATE GEOLOGIST. 



NYSSA L. Sour-gum Tree. Tupelo. 



N. sylvatica Marsh. Black or Sour Gum. 



Found in small numbers in many counties, especially in the 

 southern part of the State. Its greatest development both in 

 numbers and size seems to be in the southeastern counties. It is 

 found, however, as far north as Lake and X oble counties. Along 

 streams it reaches considerable size, but in drier localities is much 

 smaller. 



Flowering period, April and May. 



The uncleavable character of the wood makes it difficult to 

 work, although it is occasionally used in the manufacture of hubs.

A large tree, sometimes reaching a height of 100 feet, usually 

 found in deep swamps. In Indiana it is found at times removed 

 from swamps, but never in a very dry situation. 



It flowers in April. 



The wood is soft and as yet is not used in manufacture except 

 occasionally for wood pulp.
