On the Cretaceous Flora of Russian Sakhalin. 53 



27. Plat anus sp. 



Locality : Sea-sborc to the north of Mgach, besides other places. 



Some of the large leaves in onr collections seem to be allied 

 to Platanus HeerP which is quite common in the Arctic Cretaceous 

 (Atane) and in the Dakota Formation. Platanus rhomboidea Yelen.'^ 

 and PL Velenovskyana Kkassee^^ of the European Cenomanian are 

 similar to this species. Platanus Velenovskyana was recorded by me 

 from the Southern Ural."^ P. Heer I was mentioned by Eomaxowsky,^^ 

 as the single representative of the Cretaceous flora in the Semi- 

 palatinsk Province, Turkestan, and also determined by me in the 

 Upper Cretaceous of the Amur river.

There is only one impression of this leaf, 



showing a peculiar character. The leaf is 



circular in general outline, deeply bilobate 



with the sinus surpassing 2/3 of its lengthv 



The midrib is slender and runs in the direc- 



pjg ;io. tion of the median sinus, the lateral nerves 



BaiJiinia cretacea Newb. are strongcr thau tlic midrib, and fork several 



times. Newberry speaks of the great similarity of this form with
