 Nerves parallel, undivided, approaching one another at the base 

 and apex. Fructification consisting of compact strobili borne 

 terminally. 



The large size and the common occurrence of splitting of the 

 leaf-sheaths are the most important characters of this species 

 (compare Text-figs. 1 and 2).

Feistmantel l has noticed the close similarity between the Indian 

 Schizoneura and S. paradoxa from the Vosges. He states that the 

 former appears to be "somewhat stronger, and the number of the 

 leaflets composing the sheaths, larger, the sheath portions therefore 

 broader ; they also are shorter, their shape more generally oblong- 

 oval." Mr. Seward 2 has recently emphasized the close resemblance 

 between these two plants.
