118 ON THE FOSSIL FLORA OF THE COAL DEPOSITS OF AUSTRALIA, 



are found in the Tivoli mine, and as Dr. Feistmantel has already 

 suggested the distinctness of the species, I venture to give the one 

 first figured and described by Carruthers, the name of that illus- 

 trious paleontological botanist. I have compared specimens from 

 the Wannon, Victoria, side by side with the Ipswich plant, and 

 can affirm that they are quite different. 



Macrot^eniopteris. Schimper. 



Large and handsome fronds more or less broadly and elongately 

 Ungulate, obtuse or acuminate, entire or rarely irregularly pinnately 

 incised. 



The distinction between this genus and Tceniopteris is only in 

 the large and handsome form of the fronds. They are very like 

 our Australian Bird's-nest ferns (Asplenium nidus.) They are 

 common in the Oolitic coal of Richmond, Virginia, in the Lias of 

 Europe, and in the Lias and Oolitic coal measures of India. They 

 also reach the Tertiary formations, 



Macrotceniopteris ivianamaHce Feistm. (Paleoz. u. Mesoz, Flora 

 des Ost Australiens p. 107. PI. 13, f. 2.) Frond elongately 

 obovate, simple, base attenuate, apex 1 Bachis thick, grooved_'or 

 striated. Veins emerging at an angle of from 20 to 25 deg., close, 

 near the rachis from 6 to 8-tenths of a millim. apart, slender, 

 dichotomous towards the margin. See plate 10a. This fossil is 

 quoted from the Wianamatta, above the Hawkesbury sandstone. 

 I. have some similar specimens near Ipswich, but the dichotomy of 

 the veins is near the rachis and it may be a distinct species. 



Angiopteridium.* Schimper 1869. 



Frond pinnate, pinna? articulate and finally deciduous. Sori 

 when visible convex — linear, marginal, bivalvate like Angiopteris. 



The leaves of these Ferns were formerly classed as Tceniopteris, 

 and then some of them were removed to the Cycads as Stangerites. 

 The present genus was established by Schimper as noted above, 

 who showed that the specimens on which he founded his division
