The simple fronds included under this specific name are 

 characterised by a strong midrib from which numerous simple 

 or forked secondary veins are given off at a right angle or 

 slightly inclined. The breadth of the lamina decreases 

 gradually towards the petiole. The Australian species named 

 by McCoy Taeniopteris Daintreei, to which Carruthers referred 

 the Queensland fossils, has a much narrower and more linear 

 form of frond, and for this reason Tenison-Woods instituted a 

 new specific name. T. Garruthersi represents a form of leaf met 

 with in Rhaetic, or possibly Upper Triassic, rocks in S. Africa^ 

 and Australia. A very similar, perhaps an identical type, was 

 described fi-om Argentina by Geinitz'^ as T. mareyiaca : among
