This is a species hitherto not described from China. There 

 are two fragments of it, the larger (fig. 2) of which is a part of 

 a flatly pressed stem, nearly 100 mm. in diameter, with an 

 internode DO mm long. Ribs, though mostly crushed, present a 

 median ridge in well preserved portions. They are about 1 mm. 

 broad, furnished with fine longitudinal striations, and separated 

 from one another by shallow grooves. Mamelons of the nodal 

 portion are indistinct, owing to their imperfect preservation.
