CARBONIFEROUS. 01 



4 inches. A few of the stems are attached to its summit, but very few of 

 their pinnules are preserved. On the caudex are the scars from which the 

 fronds have fallen. From the size of these miniature tree-fern stems, one 

 would feel inclined to believe they had been epiphytal. 



The specimen from which Brongniart's figure of Sphenopteris stricta was 

 taken is preserved in the Hunterian Museum, Glasgow. The "strict" 

 character is somewhat exaggerated in his plate, and the fern I believe to be 

 only a varietal form of Eremopteris artemisicejolia.
