NOTES ON THE AUSTRALIAN TNIOPTERIDES. 385 
Tertiary. Sir Frederick McCoy mentions a species from a Tertiary 
deposit at Dargo (Teniopteris tenwistriatissima). In South Africa, 
India, and Eastern Australia the Zeniopteris Flora is just as well 
marked as the Lower Gondwana Glossopteris Flora that flourished 
during the preceding period, and the general facies of this Upper 
Gondwana Flora is very similar throughout these three regions, 
the remains of the old Gondwana Land. The Upper Gondwana 
Flora as well as the Lower is also well developed in South America. 
The genus 7’eniopteris was first erected by Brongniart in 1828* 
for the reception of some Paleeozoic ferns. Since that time numer- 
ous other forms very closely allied in character to this genus have 
been found from beds of different ages, mainly Mesozoic, in all parts 
of the world, and it has been found necessary to modify the diagnosis 
of the family, and to form both genera and sub-genera, not only to 
make the original genus less cumbrous, but also to make the plants 
of greater stratigraphical value. 
The classification most generally adopted as furthering these 
ends is that formulated by Schimper in 1869.+ This author divided 
Fossil Ferns into five orders, of which No, IV is that of the 
Teeniopteridece. 
The ordinal characters are—“ Fronds stipitate, simple oblong 
lanceolate, wide and elongate, entire [Feistmantel adds to this 
‘or dentate ’] or pinnate ; pinne linear or tongue-shaped, more or 
less pointed, with a short stalk or sessile. Rachis and primary 
veins stout, secondary veins springing at an acute angle, then 
becoming almost horizontal or oblique, simple and dichotomous. 
; .’ This order is founded on venation and includes the recent 
Marattiaceze, Aspidez, and <Acrostichee. From their common 
relations to these three large living families, in which classification 
is based primarily on fructification, it will be seen how uncertain 
the relations of sterile fronds are. This matter is mentioned later 
on in connection with the genera. 
The Tzeniopteridez include the following genera :— 
Teniopteris, Brongniart. 
Macroteniopteris, Schimper. 
Paleovittaria, Feistmantel. t 
Oleandridiwm, Schimper. 
Angiopteridium, ,, 
Marattiopsis, 5 
Daneites, a 
Dancopsis, Heer. 
Phyllopteris, Brongniart. 
Megalopteris, Dawson. 
Lesleya, Lesquereux.
