Mountain Basswood - Tilia heterophylla
Mountain Basswood - Tilia heterophylla, is a large tree that has the ability to reach heights of upwards of 100 feet. It is easily identified as a Basswood by the soft, light gray-brown bark that is moderately thin with long, shallow, parallel, V shaped fissures and flat topped ridges. The bark of the Mountain Basswood appears to be compressed against the tree and is molded to the ridges and fissures in a pattern that does not have rough edges. Young bark, located high in the tree smooth and light gray in color. The leaves are rounded to an abrupt tip with a coarse sharp toothed margin. The lower leaf surfaces are white and woolly. Occasionally in late Winter clusters of pea sized berries can be found dangling in a shape similar to spread fingers from the center of small, elbow shaped wings that are attached to twigs.
