514 MESOZOIC FLORAS OF UNITED STATES. 



siderable part of a penultimate pinna with a number of entire ultimate 

 pinnae and good pinnules. This is shown in PL CXII, Fig. 5. It shows 

 the character of the fern pretty well. Another specimen gives pretty well 

 the termination of an ultimate pinna. It is shown in Fig. 6. This fern, 

 from its firm texture, seems better fitted than most to be preserved. 



The following is the list of plants found at the higher exposure. No. 2, 

 at Chinkapin Hollow : 



Araucarites aquiensis Font. ? 1 specimen. 



Athrotaxopsis tenuicaulis Font ' 12 specimens- 



Equisetum Lyellii Mant. ? 1 specimen. 



Leptostrobus ? ovalis Ward nom nov 1 specimen. 



Pinus Nordenskioldi Heer ? 2 specimens. 



Sphenolepidium Sternbergianum densifolium Font 49 specimens. 



Thyrsopteris elliptica Font -_ 1 specimen. 



Thyrsopteris rarinervis Font 1 specimen. 



Ament of dicotyledon ? _ _ 1 specimen. 



This is a much smaller number of specimens than was found at the 

 locality No. 1 . Even this small number would have been diminished if the 

 material containing the fossils had preserved them no better than that of 

 locality No. 1. The indurated clay of locality No. 2 is very fine grained 

 and preserves the plants with unusual perfection, even in the smallest 

 fragments. Indeed, most of the fossils found here are small bits that would 

 not in other material be determinable.

At the same locality a seed was found that seems to be the same as 

 those described as Leptostrobus ? (6) species ? in Monograph XV, p. 231, 

 pi. cxxxvi, fig. 10. The object is composed of a nucleus surrounded by a 

 wing. The wing and nucleus together are nearly round. The nucleus, 

 not very distinctly shown in the specimen figured, is oval in form, 3 mm. 

 long and 2 mm. wide where widest, near one end. As these seeds are 



« Professor Fontaine contents himself with identifying these seeds with those found by him on the James 

 River and called "Leptostrobus ? (6) sp.?" This is an awkward designation, and as it now appears that such 

 seeds occur at other localities it is better to give them a name. — L. F. W.
