Berry : Araucarian remains 259 



transverse furrow into the scale proper and the so-called " ligule." 

 This feature is not shown in figures io and II, which probably 

 represent the transitional phase between functional scales and 

 foliage leaves toward the base of the cone, while the additional 

 variations in the specimens figured are probably likewise correlated 

 with the regions of the cone from which they came. They are all 

 preserved as impressions with fragments of lignite representing the 

 scale-substance. With the exception that they do not appear to 

 have been as thick, they are strictly comparable with the typical 

 scales of Araucaria Bidwilli. In general outline they are also 

 comparable with the scales of Araucaria Cookii of the Eutacta 

 section of the genus. Although no seeds have been found as yet 

 in the Carolina material, it seems likely that they will eventually 

 be discovered. From the structure as disclosed in the present 

 impressions it seems obvious that the scales were single-seeded as 

 in the modern genus, and, taken in conjunction with the foliage just 

 described as Araucaria blade nensis, they furnish conclusive 

 evidence of the abundant presence in the Mid-Cretaceous of 

 eastern North America of true Araucarieae, thus still further 

 increasing the parallel between the Mid-Cretaceous floras of this 

 country and those of Europe. 



Many remains of cones and cone-scales have been described as 

 species of Araucarieae but it seems scarcely worth while to enu- 

 merate them in this place. Some have already been mentioned 

 under Araucarites Zcilleri, and for others the reader is referred to 

 the monograph of Seward & Ford {loc. at.).
