Although a few of the Pennsylvanian plants examined represent new 
species and several others differ more or less from previously described 
forms it is not thought to be advisable to figure and describe those new 
forms at this time inasmuch as it is planned to include them in a later 
paper on the flora of the entire Pottsville section as represented in the 
State.
