Although a few of the Peunsylvanian 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.
