954 OLDER MESOZOIC FLORAS OF UNITED STATES. 
I have carefully examined this specimen. The nerves are too obscure to be made 
out with positiveness, and I am not sure that they are not single in each leaf. If so 
the plant isa Palissya. Mr. Wanner speaks of a second specimen which I have not 
seen. If the nerves be really numerous, as he gives them, the plant is probably an 
Araucarites, and possibly the same with the cone in his collection. 
Locality.—N. C. R. R. cut, south of York, Haven.

Mr. Wanner merely says of this that it shows the impression made 
by part of a large cone. The specimen is too fragmentary to be 
identified or described. Professor Fontaine makes it a new species of 
Araucarites, which he describes as follows: e 
This is an imprint of a portion of what must have been a fine, large cone. It is 
not complete enough to show certainly the original shape, but a globular form is 
indicated, with a diameter of about 6 cm. The impressions of the terminations of a 
number of scales are quite distinct, and they have the character of Araucarites. It 
might be called Araucarites yorkensis. This may be the cone of Araucarites ? penn- 
sylvanicus, determined from a leafy branch.

Mr. Wanner has here drawn some very clear figures of this form. 
Professor Fontaine says of it: 
Mr. Wanner regards this plant as a new species of grass. The specimen he uses 
as a type shows nodistinct features. The supposed leaves appear to me to be long 
succulent stems of some kind. I am not prepared to say that the plant is not some 
form of grass. , 
Mr. Wannev’s description is as follows: 
Graminex. Yorkia nov. gen.; leaves long, narrow, smooth, thick, and deeply chan- 
neled, with no perceptible variation in width. In the specimen illustrated, Fig. 4, 
Pl. XIV, there are no whole leaves, nor were any found, but the impressions indi- 
cate that none were less than 15 cm. in length, ranging from 1 to 2mm. in width. 
An indistinct impression at the base can be traced clearly, but can not be resolved into 
more than a faint vegetable imprint. Markings made by slender roots extend ashort 
distance below the base. No tips of leaves were observed, but Fig. 6 represents 
the nearest approach to an entire end. Fig. 5 shows the base of another cluster of 
leaves, about which is a delicate obscure mantle produced by some organic substance.
