On the Cretaceous Flora of Kiissian Sakhalin. 5 



lying one and a half kilometers inland, we discovered a flora with 

 decidedly Tertiary aspect, containing Acer, Juglans, Carpinus, 

 Quer eus etc., without any elements resembling the flora of mider- 

 lying beds. Such a presence of two diflerent floras side by side 

 has misled Schmidt and Heee. The latter, in his endeavour to 

 modernize the age of Arctic floras, has altogether neglected the 

 occurrence of Nilssonia. Schimdt thinking, that the broad-leaved 

 floras of Sakhalin are generally Tertiary, was content to explain 

 the relations of the beds at Cape de la Jonquièro by inversion,^^ 

 where steep and partly even vertical strata show the actual order 

 of succession, with basalt covering the conglomerates above the 

 Inoceramus and Ammonites beds, wliich are again underlain by 

 sandstones with broad leaves. 



During the three months of last summer I visited the western 

 coast from Cape Rogatyi to Cape Boshniak, the distance being 

 nearly one hundred kilometers. A more detailed paleobotanical 

 study was made of the seashore from Cape Spassionyi on the 

 south to the village Mgach on the north, and the inland district 

 from here to the Western Range. The plant-remains there are so 

 abundantly imbedded in nearly all the horizons of the Tertiary 

 and Cretaceous, that the quantity of materials collected was limited 

 owing to difficulties of transport and length of time at my disposal. 

 Nearly 200 outcrops with plant-remains, both Tertiary and Creta- 

 ceous, were examined. More or less complete collections were 

 made in about ten localities, on the route from Cape Khoinju to 

 Cape Tangi. 



In several localities, near Cape Rogatyi, at Cape de la Jon- 

 quière, at the coal mine " Tretya Padj " in the vicinity of Alexan- 

 drofsk, and the village Krasnyi Yar, the plant impressions were
