Common Hackberry
(Wide & Flat: Alternate Arrangement)
A small tree 20'-35' high, larger in southern Pennsylvania on moist limestone soils. Hackberry often displays a disease that causes clusters of short, dense branches called "witches brooms". A second, smaller species, Celtis tenuifolia Nutt., Dwarf Hackberry, is found on dry slopes in southeastern Pennsylvania. Fruits of both species are an important wildlife food. The wood is used for furniture, boxes and containers but not in large quantity.
