United States, Wisconsin, Sauk, 1.5 km. SSE of center of Spring Green, between Hwy. 23 and Old River Road (now only gravel)

Many trees of this species spontaneous within plantation of Pinus strobus and P. resinosa, River Valley School Forest, Spring Green unit, flat, dry and sandy terrace, to the north of a natural flooplain forest a few meters lower with Acer saccharinum, Betula nigra.
Young tree, 12 m. tall, 15 cm. in diameter. Voucher for wood specimens at Kw, Lw, MADw, MEXUw, RSAw. Staminate inflorescences creamy white, with musty, unpleasant odor, with open flowers. Pistillate flowers fewer, green. Derived from the heavily fruiting population of dozens of trees planted decades ago, in a line, with trunks to 50 cm. in diameter, all the large old ones multi-stemmed from the base, as if regenerated from fungus infection decades ago, but now the trees look healthy and a few of the oldest, largest ones apparently declining not from chestnut blight but more from the sub-optimal habitat. There is some reproduction of all size classes where there is sufficient sunlight; these saplings and young trees also look healthy.
