y. macrantlicra by the more imequal lobes and the loDger 

 stem ; from Q. mongolica by the lobes which stand more out- 

 wards and by the longer stem ; from Q. imhesccns by the larger 

 number of lobes, especially of the small ones at the top of the 

 leaf. 



I have named this species after Professor T. J. Pakkek, of 

 Dunedin.

An imperfectly-preseryed fossil leaf, of which the edge, 

 the outline, and the nervation may be so far completed that 

 its designation as an oak-leaf seems by no means uncer- 

 tain. The texture is thin, the base somewhat narrowed, with 

 a short stem ; the shape is elongated ; the width reaches 4cm. : 

 the edge is irregular and wavy, and also fringed with smali 

 sharp notches, on which the secondary nerves run, which are 

 curved. The secondary nen'es start at somewhat acute angles 

 from a stout primary nerve, which is bent irregularly. The 

 tertiary nerves, which are very delicate and mostly imperfectly 

 at preserved, start from the outer side of the secondary nerves 

 acute angles and are connected among each other. There are 

 indications of very deUcate reticulation with narrow meshes. 



I compare the leaf described with the fallen leaves of some 

 species of American oaks. Especially it seems to corre.spond 

 with those of Quercus corrugata, Hook. 



I could not find any among the known fossil oak-leaves 

 which show a noticeable agreement with the leaf here 

 described. 



Quercus celastrifolia, sp. nov.

y. foliis submembrayiaceis pctiolatis, obovato - ohlongis, 

 margine scrrato - dentatis ; nervatione craspedodroma, nervo 

 primario firvio ; nervis secundariis sub angulis S(P-40^ oricntibiis. 

 laviter arcuatis, subsimplicibus ; nervis tertiariis tenuibus, 

 angulis acntis egredientibus, reticulo obsoleto.
