upper Palaeozoic and Mesozolc Fossils. 315 



with the male flowers of Casuarina stricta. Ai'ber has re- 

 examined this specimen', which is in the Woodwardian Museum at 

 Cambridge, but he faiU^d to Hnd any leaf-sheath, and only one 

 leaf-like segment, and suggested that the striated internodes have 

 been mistaken for leaf-sheaths. Remarking on this specimen, 

 Arber says : — " The preservation of the fossil is by no means good, 

 and will only permit me to say that at each node, and on either side, 

 a bunch occurs of several small ovate bodies, apparently closely 

 attached to the node, which may be sporangia. I have not, how- 

 ever, been able to make out any sporangiophores, or further 

 details." The fructification of the Permian examples of Phyllo- 

 theca descriV)ed by Schmalhausen'^ consists of sporangia, borne on 

 peltate sporangiophores attached to the internodal area of the 

 stems between the infertile leaf- whorls. Zeiller has described the 

 fructification of Phyllotheca rallii,' in which the sporangiophores 

 alternate with the whorls of sterile bracts. 



That our second described specimen is comparable with the 

 beautiful examples from the New South Wales coal-measures 

 does not admit of doubt, on referring to the illusti'ations given by 

 Etheridge, Jun. As regards the laterally foi-med strobilus now 

 figured, attached to the leaf-sheath, it is open to question whether 

 this represents another mode of fructification for the same species, 

 but more light may be looked for on this interesting point by 

 the discovery of further specimens. In Equisetites heming- 

 wayi, mentioned above, the cones are sessile, as in our example, 

 but no leaves occur on the nodes with the cones.
