Sphenopteris germanus (M f Coy). PL X. figs. 2 &2«. 



Sp. Char. Bipinnate; pinnae oblique, alternate elongate, ovate, 

 with a narrow membranous margin ; pinnules oval, deeply pin- 

 natifid ; lobes very oblique, elliptical, generally three on each 

 side, and the apex of the pinnules three-lobed ; nerves bipin- 

 nate, three branches reaching the margin of each lobe. 

 It is extremely difficult to distinguish this species from the 

 Pecopteris Murrayana of the Yorkshire oolitic coal-fields, with 

 which it is nearly identical in form and neuration. The oval 

 outline of the pinnules is the most obvious character, contrasting 

 with the trigonal, wide-based leaflets of the English plant ; this, 

 together with their more oblique setting on the rachis, more ob- 

 lique, narrow and deeply-cleft lobes, and the decurrent, narrow, 

 alate margin to the straight rachis, will I think be sufficient to 

 distinguish the species.

Sphenopteris plumosa (M'Coy). PL X. figs. 3 &3«. 

 Sp. Char. Bipinnate ; pinnse curved, elongate, narrow, plumose, 

 with a scarcely alate margin to the rachis ; pinnules close, ob- 

 lique, ovate, pointed, deeply cleft into about four oblique mu- 

 cronate lobes on each side, exclusive of the largely trilobed 

 apex ; nerves strong, much-branched, so that about six branches 

 reach the margin of each of the lobes of the lower side, and 

 seven to each of those of the upper margin. 

 The number of lobes of the leaflets and complexity of the neu- 

 ration will readily distinguish this species. The average length 

 of the leaflets 5 lines. 



Rare in the shale of Mulubimba, N. S. Wales. 



Sphenopteris flexuosa (M'Coy) . PL IX. figs. 4 & 4 a. 



Sp. Char. Bipinnate ; pinnae very long, with a strongly flexuous 

 naked rachis ; pinnules large, moderately oblique, unequal, 

 ovate, sides cut into two very large obtusely rounded lobes on 

 each side ; apex trilobed ; nerves strong, much-branched, seven 

 branches reaching the margin of each lateral lobe, and three 

 going into each of the three lobes of the apex. 

 This strongly-marked species is not sufficiently allied to any 

 published form to render a comparison necessary. The average 

 length of the leaflets is about 8 lines, width 4 lines. 

 In a brown bed of clay, Mulubimba, N. S. Wales.
