=Distribution.=--Connecticut, southern Ohio to Missouri, south to Florida and west to Texas, and in the mountains in Mexico south to Guatemala. In Indiana it is confined to wet woods in the southern half of the State. The most northern records are from Franklin, Shelby, Putnam and Parke Counties. Wherever it is found it is usually a frequent to a common or very common tree. It is most frequently associated with the beech, but in the very wet woods it is found with pin oak, red birch, cow oak and white elm. =Remarks.=--This species grows rapidly; is somewhat hard to transplant; grows straight and tall with few side branches, and adapts itself to a wet, compact soil. In the "flats" of southern Indiana where it is associated with pin oak, red birch and beech, it is to be preferred for forest planting to these or any other species that could be grown in the "flats." It is practically free from all injurious insects. Sweet gum should be one of the principal species in wet places of the woodlots of southern Indiana. This species is one of the best for ornamental planting in all parts of the State where it is hardy. It is doubtful if it is wise to use it in the northern part of the State. Several trees in the northern part of the State are known to be quite hardy, but there are reports that it sometimes winter-kills. It can also be recommended for roadside and street planting.
