Or LOWER GREEN8A27D PLANTS. 145 



According to Carruthers, within the seeds, some of which are 

 very well preserved, lie the embryos, " and in one the section 

 is so made as to show divisions of the cotyledons." 



While this cone bears some likeness to Pinostrobus oblonyus, 

 the two seem generically distinct, as will be evident on com- 

 paring the illustrations of the originals. In the latter species, 

 for instance, the shape and relative dimensions of the exposed 

 part of the scale differ greatly from those in C. Leckenbyi, and 

 resemble Finns. 



There appears to me to be a likeness so close as to amount to 

 identity between this cone and those, also beautifully preserved, 

 described as Cidrus oblonga by Fliche (1896). Jn his pi. viii he 

 figures examples of these fossil cones, some a little smaller, and 

 one rather larger, than the type of P. Leclcenbyi, which are 

 exactly like it in all other particulars discernible. The French 

 specimens are from the Albian Greensands, and, though identified 

 by Fliche as the same species as the Abies oblonya of Lindley & 

 Hutton, I have no hesitation in including them in Cedrostrobus 

 Ltckcnbyi, which they much more closely resemble.

Diagnosis. Small oval cone, not less than 4*5 cm. long, 

 probably rather more, and about 2 cm. in diameter. Scales 

 arranged in a close spiral, overlapping so as to expose about 

 1*5 cm., more or less, in a tangential direction and about 

 3-5 mm. in a vertical direction. The scales apparently 

 thinning out at the edge and without an umbo, externally 

 striated in a vertical direction.
