Fragments of a repeatedly branched narrow woody axis, the ulti- 

 mate branches alternate, linear or short and pointed. The linear 

 branches may show what appears to be a comparatively broad midrib 

 (pi. xi., fig. 3), but usually there is no clear indication of a median 

 vein. In 1872 Carruthers described a plant from the Tivoli Coal- 

 mine, Queensland, as Sphenopteris elongata, which he defined as 

 follows : — 



" Frond dichotomously divided, each division irregularly pinnate ; 

 pinnae simple, liifurcate, or irregularly pinnate ; segments narrow 

 linear, slightly tapering upwards to the somewhat blunt apex ; 

 the single midrib sending out simple branches, which run along 

 the middle of each segment." " 



Carruthers mentions the occurrence of sori as small oval markings 

 scattered irregularly on either side of the midrib, but no trace of such 

 markings are shown in the published figure. In some of the frag- 

 ments of this plant in the British Museum Collection the central rib, 

 which stands out clearly in Carruthers' figure, is much less distinct
