Our decorticated speciraeiij which is but a mere fragmeut, 

 of this common species, agrees most perfectly with 

 Brongniart's first figure J. The internodes regularly and 

 gradually diminish in length; the striae are fine, — yet 

 distinct, and their terminations very perceptible. 



Distribution , in coal formation : — at Jarrow Col- 

 liery, Wentworth, Newcastle and Kilkenny — in Great 

 Britain; at Manebach, Essen, Saarbriick, Charlotteu- 

 brunn and Wettin — in Germany; at Alais and St. 

 Etienne — in France; at Ekaterinaburg in Russia; at 

 Cape Breton, and in Pennsylvania, — North America.
