Palceozoic Species mentioned in "Fossil Flora." 357 



Remarks. — This species is probably founded, more on a 

 condition of preservation tlian on individual definite char- 

 acters. What the authors of the " Fossil Flora " treat as the 

 apex is the base of the cone, and it is now well known that 

 the bases of the bracts bore sporoMgia, not seeds as originally 

 supposed. Lepidostrohus ornafMs might be conveniently placed 

 under Lepidostkobus variabilis, L. and H., which is a very 

 wide species. The form ornatus is frequent, especially in 

 ironstone nodules. 



PL xxvii. Sphenophyllum Schlotheimii, L. and H. 

 {not Brongt). 



Locality. — Somerset Coal Field. 



Horizon. — Upper Coal-Measures. 



Remarks. — The plant figured here is frequent in the 

 Upper Coal-Measures of Somerset, but is, I believe, the 

 Sphenophyllum emarginatum, Brongt. In Sphenophyllum 

 Schlotheimii^ the leaves are rounded in their upper margin 

 or obovate, with numerous dichotomously divided veins. I 

 have not yet met with Sphenophyllum Schlotheimii in Britain. 



Pis. xxviii., xxix. Noeggerathia flabellata. 



Locality. — J arrow Colliery. 



Horizon. — Lower Coal-Measures. Shale over the Bensham 

 Seam. 



Remarks. — Schimper has created the genus PsyTtMO- 

 PHYLLUM ^ for this and a few otlier species which were 

 formerly placed in Noeggerathia. 



Pis. xxxi.-xxxvi. Stigmaria ficoides. 



PL xxxviL Pecopteris adiantoides, L. and H. 

 Locality. — Jarrow Colliery. 



Horizon. — Lower Coal-Measures. Eoof of the Bensham 

 Seam. 



Remarks. — The figure of this plant is very inaccurately
