Infructescences of Hamamelidaceae are described from the Late Paleocene Almont flora of North Dakota. The study is based on forty-nine specimens that are preserved morphologically with some details of the fruit wall anatomy. The largest infructescence consists of up to ten sessile fruits attached to a peduncular axis 8 cm long x 0.5 cm thick. Biloculate fruits are roughly square in outline, around 10-12 mm in dimension, and have persistent, recurved styles on the distal faces of the carpels. Fruit walls are composed of elongate, interwoven fibrous cells similar to those seen in extant Hamamelis. Ellipsoid to ovoid locules are 5-10 mm long x 3-5 mm wide. Most specimens probably represent senescent fruits lacking seeds, that may have dehisced explosively like those of some modern Hamamelidaceae.
