386 PROCEEDINGS OF SECTION C. 
Of these we are mainly concerned at present with 1, 2, 4, 5, 
8, 9, and these alone will be dealt with, in the order named. 
GENERA. 
1. Teeniopteris. 
Brongniart defined this genus as Ferns possessing “simple 
leaves, entire, midrib thick and stiff, veins perpendicular, simple 
or forked at the base. Fructification in the form of puncte.” 
Since this, as above stated, the genus has been considerably 
modified by Schimper, who restricts the name 7'eniopteris to the 
Carboniferous and Permian forms with the following charac- 
ters :—‘‘Fronds simple, scolopendriform. Primary nerve (rachis) 
channelled on the upper surface, beneath almost smooth, strong ; 
secondary nerves very clear, delicate, close together, somewhat 
dichotomous towards the base, nerves simple or dichotomous, 
parallel simple nerves, not infrequently mixed with the divided 
ones. Fructification unknown.” { 
On the other hand, however, Mr. A. C. Seward, in his “ Fossil 
Plants of the Wealden,”* defines Zeniopteris as ferns possessing 
“‘ Frond simple or pinnate, usually lanceolate or linear lanceolate, 
apex acute or occasionally obtusely terminated ; a well-marked 
midrib from which lateral veins are given off either at right 
angles or more or less obliquely ; these may be unbranched or 
acutely forked as they pass towards the leaf margin.” He pro- 
poses to use Z’wniopteris in the same broad sense as Nathorst,} 
including under the one comprehensive term Oleandridium, 
Angiopteridium, Marratiopsis, Danceopsis, Macroteniopteris. 
So far as we know at present no Paleozoic 7eniopteris has 
been described from Australia. In the collection of the Mining 
and Geological Museum there are two imperfect specimens of a 
fern showing a well-marked midrib, veins running obliquely to 
the margin, no anastomosis and only infrequent furcation, apex 
and base unknown. It is very probably that more perfect speci- 
mens will show this to be Zentopteris. It is from the Greta or 
Lower Coal Measures and the fragments are contained ina portion 
of the core of the Rutherford Bore.§
