shaped entire, but often deeply lobed or toothed, ‘on 
median nerve, and the minor nerves frequently forking. 
Annularia , — Leaves in close horizontal whorls, 
numerous, oval or tongue-shaped, with a medium rib. 
Schizoneura is a rather common Indian fossil, of 
Secondary age, which has never been found with our 
Permo-carboniferous coals, but was recognised in the 
Cremorne Bore, in beds of Triassic age. 
Most of the other genera mentioned need not occupy 
us, as they are rare. Schizoneura had a sheath also, 
and a number of longitudinal leaflets with a central 
vein attached along their margins. See reference to a 
figure of this plant in the list of fossils at the end of 
this volume. Sphenophyllum has been found in frag- 
ments only at Port Stephens, and Annularia at Greta 
Creek. They are both Palaeozoic forms, and almost 
confined to the Coal Measures.
