Plant Identification
An intolerant tree on bottomland sites of the mid-Atlantic coast and Midwest with a distinctive form. The common name refers to the "pin-like" persistent small branches and the scientific name refers to wet site. It is a common ornamental but chlorotic on high pH sites. Leaves are deciduous and deeply lobed with broad "u-shaped" sinuses and axillary tufts below. Twigs are 1/8", acute, and glabrous. Fruit is to 5/8" long, with an often striate nut with a thin saucer-like cap with appressed scales. Bark is smooth for many years and eventually develops low, scaly ridges.
