FOSSIL PLANTS, 95 
Newark, N. J. The decorticated surface of these stems is marked by rhom- 
boidal elevations, which somewhat resemble the markings on the trunks of 
Lepidodendron when denuded of their coaly envelope. This resemblance has 
led to the announcement that Lepidodendron had been found in our Triassic 
rocks, but this is a manifest error. Lepidodendron did not pass from the 
Carboniferous to the Mesozoic age, and these are plainly casts of the trunks 
of coniferous trees. 
Since this was written my attention has been drawn to a figure of the 
trunk of Voltzia Coburgensis Schaur (Paleontographica, vol. 11, p. 308, 
Pl. XLVI, Fig. 2). This is so much like the trunk now figured and the 
smaller ones not uncommonly met with in the quarries at Newark, that if 
we had anywhere found in the Trias of this region any certain traces of 
Voltzia 1 should have little hesitation in referring our specimens to that 
genus; but no Voltzia has yet been found in the New Jersey sandstones, 
while Palissya is rather common. Hence, I have been led to believe that 
these trunks and branches bearing lozenge-shaped markings belonged to 
the latter genus. As it was doubtless closely allied to Voltzia it would not 
be at all surprising if we should find that the decorticated trunks of trees 
of the two genera were much alike.
