Palceozoic Species mentioned in "Fossil Flora." 359 



to the Neuroioteris cordata, Brongt.^ In my paper on the 

 " Fossil Flora of the Eadstock Series," the subject has been 

 fully discussed.^ I may merely mention here, that the true 

 Neitropteris cordata, Brongt., has not yet, as far as I have 

 seen, been discovered in Britain, and that Lindley and 

 Hutton's plant, as well as all other British specimens that I 

 have seen passing under the name of Neuroyteris cordata, are 

 the NEurvOPTERis Sciieuchzeri, Hoffmann.

PI. xliii., figs. 1, 2. Cyperites bicarinata, L. and H. 



Locality. — Leebotwood, 4 miles from Church Stretton, 

 Shropshire. 



Horizon. — Coal-Measures, 



Remarks. — The grass-like leaves placed under Cyperites 

 hicarinata are the foliage of Sigillaria, and possibly of some 

 species of Lepidodendron. 



■ These fossils, as far as I have been able to observe, have 

 not two veins as supposed by Lindley and Hutton. The 

 little ledges, formed by the two sides of a flat, central, single 

 vein, form protected lodgments for the carbonaceous matter 

 of the leaf, and often, after the greater part of this substance 

 has been removed from the other portions of the fossil, the 

 prominence of these two lines of carbonaceous material, 

 which frequently conceal the two edges of the mid-rib, have 

 given rise to the erroneous opinion that the leaves contain 

 two veins. 



LepidophylliLm trinerve, L. and H., and Lepidophyllum 

 hinerve, Lebour, are subject to the same explanation.
