were really Ferns but differing from Tceniopteris in having 

 deciduous pinnae. I need scarcely say that the living Ferns 

 which these species most resemble never have deciduous leaves. 



Angiopteridium ensis. Oldham. Fossil Fl., Rajmahal Hills. 

 (Foss. Fl. Gondwana, vol. 1, p. 35, pi. 6, figs 8, 9, 10.)— Frond 

 pinnate, pinnae elongate, linear ovate, acuminate at the apex • 

 costa thick, rapidly diminishing ; veins prominent, often forked 

 once or twice, emerging obliquely from the costa. 



This variety is easily distinguished from the other forms by the 

 obliquity of the secondary nerves, by the rapid thinning out of 

 the midrib, and by the generally subovate or lanceolate form of 

 the pinnule and the forking of the veins near the edge of the leaflet. 

 A false serration is another distinguishing feature. 



I know of nothing to prevent my referring the fossils which are 

 found at Rosewood, near Ipswich, Q.L., to this form, as it corre- 

 sponds exactly with the figures and with the description. I must 

 confess that I should at first been inclined to regard the specimen 

 as a Fern very near in habit to Blechnum* 



The affinities of this species are Jurassic and Rhaetic. 

 Sub-order. Djctyopteride^e. 



Nerves reticulate, fronds many times pinnate or pinnatifid.f 



A. With a midrib. 



a. Costa conspicuous, frond simple. Glossopteris. 



b. Costa inconspicuous, except in the middle, frond quad 



rilobate. Sagenopteris. 



B. Without a costa. Gangamopteris. 



Glossopteris. JBrongniart. 

 Fronds simple, elongately elliptical, acuminate, entire, coriaceous, 

 petiolate, rachis broad, gradually tapering up to the apex. Veins 

 emerging from the rachis at an acute angle, from which to the 

 middle of the leaf they form a hexagonally rhomboid net ; thence 

 to the edge somewhat more free, dichotomous, not so often anas- 

 tomosing, and forming very large rhomboidal areolae. Sori rounded
