An eastern North American deciduous tree (Castanea dentata
) having narrow toothed leaves. It was once valued for its timber and nuts but is now found mostly as sprouts from old stumps, the aboveground parts having died from chestnut blight.http://www.efloras.org/florataxon.aspx?flora_...

The American chestnut was one of the most important dominant forest trees of eastern North America prior to 1930.
After 1930, most populations of Castanea dentata
were nearly destroyed by the chestnut blight, caused by the introduced fungus Cryphonectria parasitica
(Murrill) M. E. Barr [= Endothia parasitica
(Murrill) P. J. Anderson & H. W. Anderson]. While chestnuts persist in many localities, the plants are mostly resprouts that rarely, if ever, produce viable seed.
Virtually all known natural populations remain infected with the blight, […]http://www.missouribotanicalgarden.org/PlantF...Castanea dentata
Common Name: American chestnut
Once a major component of the Eastern hardwood forest, American chestnut is almost extinct in the wild now, having succumbed to chestnut blight, a bark fungal disease that probably entered the U.S. in a shipment of nursery stock from Japan in the late 1890s. American chestnut now persists mostly in the form of sprouts from old stumps and root systems. […] Before blight introduction, mature trees typically reached 50-75’ (occasionally to 100’) tall with globular spreading crowns.
