This plant may have been the same as Zeugophyllites australis, 

 Morr. It must be remembered that the latter genus was established 

 by Brongniart for a plant with leaflets such as these, but in pairs. 

 In the plants found at Jerusalem, Tasmania, and classified by 

 Morris as Zeugophyllites there was nothing to show that the leaflets 

 were in pairs. The form of the Leaf alone guided Prof Morris in 

 his determination ; and that form was so similar to the leaves 

 described above that they may have been the same. For the 

 present I must leave the matter as it stands. There is only one 

 species of this plant, but I note, also, leaves of the same shape 

 associated with them, but in which the coriaceous epidermis is 

 almost smooth in consequence of the fine, close nerves. In 

 these leaves there are sometimes faint traces of a midrib also ; 

 leaves larger and coarser than the foregoing, with which they are 

 always associated. The nerves are only four or five, and the leaf 

 has a rough appearance. Also a fossil which may be the same as 

 P. hacketi, Feistm. (I.e., p. 92, pi. 7, fig. 4, 5, 4a, 46, 5a,) in which 

 the leaf is broader, springing from a thick rachis, veins numerous 

 with an indistinct median nerve like a midrib. Dr. Feistmantel 

 found it in connection with the rachis and compared it with Heer's 

 P. plicatus from the Amur countries. The number and variety 

 of the leaves at Ipswich makes that deposit peculiarly advanta- 

 geous for their study. It is one of the many instances of the 

 fact that we meet with a fossil in Australia, which is world-wide 

 in its distribution. 



Ptilophyllum. Morris. 



(As amended by Schimper.) Paleozamia (Ptilophyllum), Oldham 

 and Morris. Leaves rather long, petiolate, petiole exactly terete, 

 graceful, feather-like (whence the name), linear-lanceolate, gradu- 

 ally acuminate towards the summit, sometimes narrowed below. 

 Leaflets of equal size, affixed to the rachis by the anterior side and 

 somewhat imbricate there, flat, coriaceous, linear, apex obliquely 

 acuminate above and slightly curved, the superior angle of the base 

 rounded, sub-auriculate, free, the lower and fixed portion acute 

 and slightly decurrent. Fructification strobiliform ; seeds small, 

 ovate, oblong. Stipe cylindrical, narrow.
