Rhacophyllum Goldenbergii, Weiss in Schimper, Traite d. paleont. veget., vol. i. p. 686, pi. xlvi. 

 fig. 2. 



Description. — Frond membranous, pinnate (?) ; pinnse lanceolate, pinnatifid ; 

 teeth of pinnae directed upwards, simple or bifid, lanceolate acute. Midrib 

 distinct, and giving off a veinlet to each tooth. Main rachis broadly winged, 

 in which can be traced, for a considerable distance, the downward course of 

 the midribs that enter the pinnae. 



Remarks. — This species is extremely rare in the Radstock Series, only two 

 specimens having been observed, both of which are in the collection of Mr 

 J. M'Murtrie, F.G.S. The example figured, however, is from Pucklechurch,* 

 and was presented to the Bristol Museum by Mr J. C. Blackmore. 



The frond appears to have been of very delicate membranous character, in 

 which the veins are distinctly seen. 



In one of the specimens of this species in Mr M'Murtrie's collection, the 

 midrib of the pinnse appears thicker than in that figured, but the condition of 

 preservation in the two specimens is different. That figured shows the upper 

 surface of the frond, the carbon remaining as a thin brown film, whereas in the 

 other examples an impression of the under surface of the frond is exhibited, 

 from which the carbonaceous matter is entirely removed. 



The British specimens agree very well with the figure of Rhacophyllum 

 Goldenbergii given by Schimper, but the Saarbruck example does not seem to 

 have been so well preserved as that from Pucklechurch. The teeth of the 

 pinnatifid pinnse appear to be simple, with the exception of the basal tooth 

 on the superior margin, which is bifid. 



As far as I am aware, this plant has hitherto only been recorded from 

 Saarbruck. 



Locality : — Kadstock. 



* This specimen is probably from the neighbourhood of Pucklechurch — not actually from the 

 village of that name, and therefore most likely from a bed on the horizon of the Farrington Series, 

 i.e., the coal-producing series immediately below the Eadstock Series.
