A conical tree, reaching a height of about 70° and a trunk diameter of 50, the old bark decidu- ous in ragged strips. Scale-like leaves of the ultimate branchlets nearly orbicular, obtuse, l"-ii" broad, the two lateral rows keeled, the two other rows flat, causing the twigs to appear much flattened; leaves of the older twigs narrower and longer, acute or acuminate; cones 4"-6" long, their scales obtuse; seeds broadly winged. In wet soil and along the banks of streams, form- ing almost impenetrable forests northward, New Brunswick to James' Bay and Manitoba, south to New Jersey, along the Alleghanies to North Caro- lina, Tennessee and to Illinois and Minnesota. As- cends to 3500 ft. in the Adirondacks. Wood soft, brittle, weak, coarse-grained, light brown; weight per cubic foot 20 lbs. Called also False White and Feather-leaf Cedar. May-June. 8.
