GLOsSGl'lEUIS. 



out, Brongniart's original figure is incorrect ; the lateral nerves 

 forming anastomoses quite to the margin, although individual 

 nerves may here and there remain free from one another for a 

 short distance. 



The very long and narrow leaves from India, figured hy 

 Bunbury 1 as G. leptoneura, would seem to be hardly distinguishable 

 except in size and shape from G. angmtifolia. The lateral nerves 

 are very oblique and fine, the meshes being somewhat more polygonal 

 than in that species. This form is known only from the Nagpur 

 district in India, and might conceivably be regarded as a variety of 

 G. angmtifolia. Characters depending on size and shape, especially 

 in dealing with fronds of such varied habit as those of Glossopteris, 

 seem to me to be extremely untrustworthy, and for the present it 

 appears to be better to include the Nagpur leaf with G. angmti- 

 folia. Bunbury's type-specimens (Nus. B. 10,360-2) are preserved 

 in the Museum of the Geological Society of London. 



Some very imperfect fragments, somewhat recalling Bunbury's 

 plant, were figured by Feistmantel 2 as G. tamioides, a type of 

 narrow linear leaf with a strong midrib, but with few meshes in the 

 network. This species may probably be also best included under 

 67. angmtifolia ; at any rate, the evidence is too imperfect to 

 warrant a new specific name. 



Feistmantel 3 has figured a number of fronds radiating from 

 a stem -like structure under the name Sagenopteris longifolia. 

 I have no hesitation in regarding these as fronds of G. angmtifolia 

 attached to a rhizome. Zeiller has already expressed the same 

 opinion. The specimen also figured by Feistmantel as Sngennpteris 

 cf. rho/fulia 4 is possibly a scale-frond or a small frond of Glossopteris.
