NEW SPECIES AND A NEW GENUS OF DEVONIAN 
PLANTS. 
By G. F. Matthew, LL.D., D.Sc., F.R.S.C. 
Read February 4, 1906, 
Some members of our Society have, during the past summer, 
given a good deal of attention to the collecting of minerals and 
fossils around the city. Two of these gentlemen, Messrs Wm. 
McIntosh and A. Gordon Leavitt, in their quest have visited the 
localities for fossil plants, which some forty years ago yielded a 
rich flora of Devonian age to the labors of former members of our 
Society, and have been fortunate in discovering some new plants 
in the Dadoxylon Sandstone. The plants described in this paper 
were taken by them from beds about 200 feet below the summit of 
these sandstones, and therefore that distance below the prolific 
measures of the Lower Cordaite shales which had been worked 
by myself and the late Professor C. F. Hartt, and at a later date 
by Mr. W. J. Wilson. 
I shall first describe a very interesting form obtained by Mr. 
McIntosh. 
Pseudobaiera, n. gen. PI. VIII. 
This genus is represented by certain thick smooth leaves 
which in appearance and structure combine the characters of 
Filicales and Ginkgoales. The leathery leaves having strap like 
lobes, ending in mucronate points recall Baiera, while the general 
port of the plant is that of a fern. 
The frond is tripinnate and seems related to Eremopteris, and 
Triphyllopteris. It is regularly alternately pinnate, the pinnules 
deeply cleft into strap-like lobes, which lobes also are alternately 
pinnate and decurrent on the mid-rib. Venation obscure, owing 
to the thickness and smooth surface of the pinnules.
