[Amoenitates Exoticse, p. 811, 1712.] 



The application of the recent generic name Ginkgo to fossil forms 

 has become so thoroughly established, that it seems inadvisable 

 in this case to add the usual termination ites when using the 

 designation for extinct types. 



Ginkgo digitata (Brongniart). 



[Hist. veg. foss. p. 219, pi. Ixi. bis, figs. 2-3, 1828.] 



(PI. XI. Fig. 3; Text-fig. 9.) 



The synonymy of this species is given at length in vol. i. of 

 the Jwassie Flora ' ; the following additional records may be added 

 as having reference to leaves which I believe to be identical with 

 Ginkgo digitata.
