Dichophyllum Moorei and Certain Associated Seeds

A few years ago Elias (Moore et al., '36) described a flora from the Upper Carboniferous of east-central Kansas which contained certain elements such as Walchia and Taeniopteris, plants generally accepted as more typical of higher horizons. In many ways the most interesting and certainly the most novel member of the flora is the plant described as Dichophylltum Moorei (fig. 1). In the hope that a more detailed knowledge of it might shed light on the general problem of leaf morphology in the seed plants we visited the type locality in the summer of 1939 and made a small collection. Excavations carried on during the following summer yielded some excellent specimens, and although much remains to be known about this interesting fossil sufficient information has been obtained to warrant a short note on its gross morphology.
