[CH. 



Cyparissidium is characteristic of Lower Cretaceous strata 

 though Nathorsti has recorded a species, C. Nilssonianum, from 

 Rhaetic rocks in Scania with cones having scales more pointed 

 and lanceolate than those of Heer's species. A second Rhaetic 

 species, C. septentrionale, has been transferred by Nathorst to the 

 genus Stachyotaxus^ .

The type-species (fig. 810, A, B) is one of the most abundant 

 plants in the Kome beds at Pattorfik in West Greenland and it 

 occurs also in the Atane beds. The cones are 2G mm. long and 

 11 — 20 mm. broad with scales having a breadth of 12 mm., a
