VEGETABLE REMAINS. G^/T JND IHONSTONE. 
FIG. 1 , 2 . 
PHYTOLITHUS (arundineus) Graminis ? trunci 
simplicis recti teretis : articulis longituclinaliter stri- 
atis ; strils asqualibus confertis. S. t. 
A fossil vegetable. The original the trunk or culm of a 
Grass ? Simple, straight, round, jointed ; the joints nu- 
merous, short, and longitudinally striated — the str’uc close 
and equal. 
Found with other vegetable remains, in tlie argillaceous 
strata, near Alfreton, Chesterfield, &c. 
This fossil differs from the Phytolithus figured at plates 
8, 9, in having the joints marked with superficial close 
lines. Instead of deep and distant furrows — Both species are 
found to vary considerably in thickness — from that of a 
reed, to four or five inches in diameter : but the character 
of each appears constant, throughout this variety of size. 
We think ourselves justified, therefore, in considering 
them as distinct; at least till accurate observation shall have 
proved the contrary.
