60 Mr. E. Kidston on British Carboniferous Lycopods. 



IX. — Additional Notes on some British Carhoniferous 

 Lycopods. By R. Kidston, F.R.S.E., F.G!S.* 



[Plate IV.] 



The present paper must be regarded as an appendix to that 

 published by me in the Ann. & Mag. Nat. Hist, in 1885 f. 

 Since that communication was written several important 

 works dealing with the Carboniferous Flora have appeared 

 which contain additional information regarding the Carbon- 

 iferous Lycopods. I have also continued my investigations 

 on this subject, and now wish to lay before this society some 

 of the results. These are partly confirmative of the views I 

 previously stated and partly correcting errors into which I 

 had fallen. 



I. Lepidodendron Veltheimianunij Sternb. 



A few months ago I received for examination from tlie 

 Geological Survey of England an impression of Lepidoden- 

 dron Veltheijnianum, collected by Mr. Rhodes, one of their 

 fossil collectors, from the Lower Carboniferous of Lumby 

 Law Railway-cutting, ^ mile north of Edlingham Church, 

 Northumberland. It was contained in an iron-stained sand- 

 stone and showed on the surface of the impression the leaf- 

 scars and one of the large cone-scars. Attached to this latter 

 is the basal portion of the appendicular organ which had 

 been imbedded in the matrix, and from the fortunate manner 

 in which the block containing the specimen has split one 

 side of the appendicular organ is exposed. It is directed 

 upwards and therefore similar in position to that of all the 

 other specimens of the plant which have shown the appen- 

 dicular organ i7i situ. Owing to the rough nature of the 

 matrix the minute structural points of this organ are not 

 shown ; but the impression of the fossil is sufficiently well 

 preserved to enable a satisfactory identification of the species 

 to be made, and, further, to confirm the opinion that the organ 

 in question is a cone. 



My thanks are due to Dr. A. Geikie for the opportunity of
