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



is not more oblique than that of G. browniana or G. milsoniana. 

 In this species also, from the anastomosing being continued up to 

 the margin, it results that the veins are little closer at the margin 

 than at the middle of the leaf, while in G. augusti/olia, the 

 anastomosing is continued to the central portion, and the dichoto- 

 mosing goes on to the margin, where in consequence the neuration 

 is finer and closer than towards the costa. None of the specimens 

 are perfect at the extremities, the largest being three inches long 

 and seven lines wide at the basal fracture, and diminishing about 

 two lines in that length, towards the distal end, being about eight 

 lines wide in the middle. Disconnected fragments show that the 

 base diminishes insensibly to a lengthened petiole, as in 

 G. brovmiana, and that the apex is elliptical and pointed. Very 

 abundant in the grey shale at Wollongong. Not uncommon in 

 the hard siliceous schists of Arowa, N. S. Wales." Abundant also 

 in Newcastle. 



Glossopteris ampla Dana (I.e. p. 717, pi. 13, fig. 1,) also Feist. (I.e. 

 p. 91, PI. 11, fig. 2, pi. 12, 17.)— Frond very large, widely ovate, 

 entire, undulating, obtusely acuminate, costa thick, extending to the 

 apex ; veins, extremely fine and close, leaving long narrow 

 reticulations, which are longest towards the margin. Locality — 

 Newcastle, Illawarra. 



Glossopteris reticulata, Dana (I.e. p. 717, PI. 13, fig. 2,) — Frond 

 large, oblong-elliptical, the width not exceeding a third part of the 

 length, gradually attenuate towards the apex ; veins, broadly 

 reticulate to the margin. Locality — Newcastle. This is a rare 

 form. 



Glossopteris elongata. Dana (1. c. p. 717.) Frondnarrowly elongate, 

 lanceolate, attenuate at the base ; costa somewhat thick, distinct ; 

 veins neatly reticulate. Locality, Newcastle. 



Glossopteris cordata. Dana. (I.e., p. 718., pi. 13, fig. 5.) Frond 

 distinctly cordate towards the base, lobes rounded ; costa, thick ; 

 veins reversed at the base, diverging from the costa, neatly 

 reticulate, with narrow oblong interspaces. Locality, Illawarra. 



All the above four species of Dana are considered by Feist- 

 mantel to be only varieties.
