Abstract
A new species of the coenopterid genus Tubicaulis (T. scandens Mamay) is described; the description is based upon a single coal-ball specimen from the Upper Pennsylvanian of Illinois. This is the first reported occurrence of Tubicaulis in American fossil floras. The type specimen apparently grew as an epiphyte on a Psaromus trunk, with its roots penetrating into the tissues of the support, thereby providing a firm anchorage. It was a long, slender rhizomatous plant, with long internodes and certain dorsiventral anatomical features; in these aspects it presents some interesting points of contrast with previously described species of Tubicaulis.
