oblong, acuminate or obtuse, base contracting suddenly and 

 fixed to the anterior side of the rachis by a more or less distinct 

 callosity ; solidly coriaceous. Nerves distinct, straight, parallel, 

 ending abruptly at the apical margin of the leaflet. 



In this genus are grouped Cycads with straight parallel nerved 

 leaflets abruptly constricted at the base, fixed at the centre of that 

 base on a callosity. They are mesozoic plants which make their 

 appearance in the Oolitic period, and continue to the present day. 

 It is not certain that the fossils are in every case true Cycads, as 

 the fructification has seldom or never been seen. The female 

 cone of Zamites ejnbius, Saporta, and some few others have been 

 found. 



In this genus Dr. Feistmantel includes Podozamites, regarding 

 the latter as a sub-genus. It was recited by Braun and is adopted 

 by Schimper, M'Coy and others, and on that account I think it 

 better to continue to give it generic distinction. Up to this no 

 true Zamites have been found in Australian plant beds. 



Podozamites. Fr. Braun. 



Leaves of medium size. Leaflets distant, spreading, oblong, 

 ovate, and linear-oblong, apex obtusely acuminate or rounded, 

 gradually narrowed towards the base, subpedicellate, pedicel 

 articulate, deciduous. Nerves dichotomous at the very base, then 

 simple, erect, parallel, then converging towards the apex. 



This genus differs from Zamites proper in the oval, oblong, or 

 elongate leaflets, more or less obtuse above and gradually narrowing 

 below, inserted on a pedicel at an acute angle, with nerves 

 dichotomous at their origin, but rarely dividing afterwards, 

 inwardly curved and converging towards the top. Three species 

 are already described. 



Podozamites barkleyi, M'Coy (Pal. Vict., p. 33, pi. 8, figs. 1, 2, 

 and 5 .) Fronds from one and a half to two and a half inches 

 wide, rachis thick, about one and a half lines wide, pinnules close 

 set, narrow linear, elliptically pointed at the distal end, about one 

 inch five lines long and one line wide in var. gracilis, and one inch
