around the stem, which probably belongs to G. Sagenaria. 
2, Leaves setaceous arranged in two rows and not appear- 
ing to leave reticulated impressions. 3. Leaves broad, 
without apparent nerve, scattered and inserted without or- 
derall around the stem. ‘hese are found only in the bi- 
the aquatic mosses. Only the last section is found in the 
superior formations. In the inferior sediment, the third 
section is found at Mansfeld and a species with thrice pin- 
hate divisions in the Oxford oolite. The true Lycopodites 
or those of the second section are very abundant in the 
coal formations, but are not found ia any more recent for- 
mations. The Lycopodites are not all distinctly referable 
to the Lycopodia; but the two first sections may be consid- 
ered analogous. 
2. Filicites. Frond disposed on the same plane, symme- 
trical; secondary nerves simple, dichotomous, or rare 
ferns.” The five sections. 1. Glossopteris—frond 
simple, entire, traversed by a single median nerve, without 
distinct s nerves; resembles ophioglossum, but in 
analogous in structure, though not in form, to no- 
Phyllum. Only one specimen of filicite has been observed 
: i superior formations, and this very 
“‘temely abundant in the coal and anthracite formations to 
‘4 theyseem peculiar. There is no ce example 
of them in any more recent formations.
