SCHIZONECRA. 13 



at the base or altogether free, 15-30 mm. long, 1-5-2 mm. broad, 

 erect, more rarely arched and recurved, narrow, lineardanceolate, 

 with a not very distinct median nerve. 



The surface of the leaves in this species appears to be rather 

 thick, and uniformly striated lengthwise by very fine and close 

 lines, which in the median region become better defined and 

 constitute a more or less distinct median nerve. The variation in 

 the degree of union of the leaves suggests that these plants should 

 be referred to Schizoneura. Zeiller states that this species appears 

 to be near that known as S. meriani (Brong.). 



S. Wardi is known only from the Karharbari Beds at 

 Sasserabhia, India. 



Not represented in the British Museum collection.

 restored. 



In a paper read before the Geological Society of London in 

 1852, Hooker described a specimen discovered by Bain in the 

 Roggeval (Fish River), South Africa. It shows some whorls of 

 leaves united into a cup or sheath at the base, the free segments 

 being of unequal length and breadth, and each traversed by a few 

 parallel and distinct nerves. Some of the leaves show signs of 

 splitting at the apex. Hooker was unable to offer any suggestion 

 as to the nature of this plant. Bain, 1 however, speaks of it as 

 Asteropln/Uites (?). 



Feistmantel suggested, in 1890, that this may possibly be a 

 Schizoneura, at the same time remarking that the number of 

 segments of the leaf-sheath is much larger than in S. gondwanensis, 

 and their substance is thicker and more leathery. He suggested 

 that if this generic determination be accepted, the species
