GLOSSOPTERIS. 83 



Frond of Glossopteris, sp., from Natal. 



V. 2903. This specimen is labelled Tamiopteris, but it is 

 obviously a Glossopteris, since the lateral nerves clearly anastomose. 

 It is a broad frond, which must have been 10 cm. or more across. 

 The midrib is missing. The nerves are nearly parallel, and 

 anastomose apparently at long intervals. Although it is not 

 sufficiently perfect to identify specifically, it may be compared 

 with G. ampla.
