^— of 1903 (= ^— as previously reported under wrong number) . 



These specimens embrace, in addition to fragments of Cyperacites haydenii, 

 as already discussed, one fragment of a Cyperacites of unknown species, which 



must be referred provisionally to the group embraced in — — etc. In addition 



4, 10 



there are a large number of fragments of seeds and leaves of an undeterminable 



character, but which may belong here.

-5- of 1903. Undeterminable. 



o 



Two fragments of small stems or leaves, a few cm. long by a few mm. wide. 

 There is no evidence whatever of structure, and it is impossible to satisfactorily 

 correlate them with any known forms. 



250 



-Q- of 1903. Fern stipes. 



A single specimen, representing a portion of a branching stem which 



exhibits no detailed structural features, but has all the external aspects of a 



portion of a fern stipe bearing the basal portion of the rachis of one of the 



pinnse. As such, the specimen has no stratigraphical value, since the species or 



271 

 genus cannot be determined ; but it is highly probable that it is identical with —r- 



of the same collection, which represents fragments of stems only two or +hree 

 centimetres long, mingled with fragments of 'leaves.

of 1905. Betula, sp. 



c 



Under this number are included isolated specimens about 1 cm. long by 

 0-5 cm. wide, evidently the remains of a fruit of some sort. A careful inspection 

 shows it to be made up of a series of closely packed scales which make it an 

 oblong cone closely comparable with the cone of Betula, to which it is provi- 

 sionally referred.

Among the collections of 1903 were two fragments of calcified wood, both 

 of which represent the same species. The larger specimen was a fragment of 

 a good sized but flattened branch, measuring about 10 cm. in length, 9 cm. in 

 breadth and 2-8 cm. in thickness. The structure was well preserved and admitted 

 of determination without much difficulty, although decay and alteration by 

 crushing had obliterated and destroyed some of the structural features. There 

 was no difficulty in recognizing the wood as representative of a hard pine, but
