GiMKGO CF. MAGNiFOLiA, Fontaine. 



(Plate 4, figs. 3, 4.) 



1905. Ginkgo Huttoni magnifolia, Fontaine in Ward, U.S.G.&., 

 Mon. 48, p. 124, t. 31, fig. 8. ' 



Under this name are included some larger specimens which 

 resemble somewhat Fontaine's G. Huttoni magnifolia.'^ 



The leaf is large, divided into a few wedge-shaped segments 

 (usually two or four) which are about 7 cm. from base to outer 

 margin. The petiole is about 3-5 mm. wide just below the leaf. 

 The veins divide dichotomously and are about 1 mm. apart. 



Fontaine retains G. Huttoni as a species separate from G. 

 digitata and remarks that his variety magnifolia only differs from 

 other examples of G. Huttoni in size.^ Knowlton,^ however, in- 

 cludes both G. Huttoni and G. Htdtoni var. magnifolia under G. 

 digitata. 



The specimens described here differ most from the variety 

 mentioned in the large wedge-shaped segments, and it does not 

 seem reasonable to include them in G. digitata, even allowing that 

 species a very wide variation. There is a general resemblance in 

 size and in the character of the venation with Baiera sformbergensis 

 from the Stormberg Series of South Africa. ^°
