MR. R. H. GOODE ON THE FOSSIL FLORA OF 



[June 19 13,. 



Further, the following nineteen species have been obtained from 

 the Lower Coal iSeries of Pembrokeshire, but have not been recorded 

 from the White Ash Series ; they are, therefore, additions to our 

 knowledge of the Middle Coal Measures of South Wales : — 



Mario pteris latifolia (Brongn.). 

 Nevropteris obliqua (Brongn.). 

 Neuropteris scheuch&eri Hoffm. 

 Alethopteris serli (Brongn.). 

 Pecopteris pktmosa (Brongn.). 

 Cardiocarpus fluitans Dawson. 

 Lepidostrobus cf. variabilis L. & H. 

 Cordaites borassifolius (Sternb.). 

 Cordaianthus piteairnim (L. & H.). 



Catamites cisti Brongn. 

 Catamites schutzlarensis Star. 

 Calamocladus gravdis (Sternb.). 

 Palcsostachya pedunculata Will. 

 Annularia radiata Brongn. 

 Annularia sphenophylloid.es (Zenk.). 

 Annularia gal 'ioid.es (L. & H.). 

 Sphenopteris schilling sii Andrss. 

 Sphenopteris cf. sauveuri Crep. 

 Sphenopteris furcata (!) Brongn. 



Furthermore, from the ; Pennant Grit' of Pembrokeshire, which,, 

 as we have seen above, may be regarded as belonging to the Middle 

 Coal-Measure horizon, the following thirteen species have been 

 obtained. These species have not been recorded from the Lower 

 Coal Series, either of Pembrokeshire or of the main portion of the 

 South Wales Coalfield, and may therefore be regarded as additional 

 records to those mentioned above for the Middle Coal Measures of 

 South Wales : — 



Annularia ingens, sp. nov. j Linopteris brongniarti Gntb. 



Sphenophyllum cmieifolium cf. var. | Linopteris sub-brongniarti Grand'Eiiry. 



Linopteris major, sp. nov. 

 Cardiocarpus acutus L. & H. 

 Lepidodendron lycopodioides Sternb. 

 Lepidophyllum minus, sp. nov. 

 Sigillaria ovata Sauv. 



saxifragafolium (Sternb.). 

 Sphenophyllum ma jus Bronn. 

 Sphenopteris spinosa Goepp. 

 Sphenopteris cf. Sph. (Eenaultia) 



gracilis Brongn. 

 Linopteris munsteri (Eichw.). 



It will be seen that, although both the Lower Coal Series of 

 Pembrokeshire, including the ' Pennant Grit,' and the White Ash 

 Series of the main portion of the South Wales Coalfield are Middle 

 Coal Measures, there is considerable difference in the occurrence of 

 the species. There are, however, more species common to these 

 beds than to the ' Pennant Grit ' of Pembrokeshire, by itself, and 

 the Lower Pennant of the main part of the South Wales Coalfield. 



It is not possible to compare the fossil flora of the so-called 

 'Millstone Grit' of Pembrokeshire with that of these beds in the 

 main portion of the South Wales Coalfield, for there are no 

 records from the latter beds. 



VI. Conclusions. 



Of the fifty-three species here recorded from the Pembrokeshire 

 Coalfield, three are new species, and one, Linopteris brongniarti 

 Gutb., has not with certainty been found before in Britain. 



From the paloeobotanical evidence it has been shown that the 

 'Pennant Grit' of Pembrokeshire cannot be regarded as the 

 equivalent of the Pennant Grit of the main portion of the South 

 Wales Coalfield : for the plants indicate that these beds are Middle
