348 MR ROBERT KIDSTON ON THE FOSSIL FLORA OF THE 



trichomanoides is simply a pinna of Sphen. furcata, Brongt., and Zeiller, though 

 he includes Sphen. trichomanoides in his " Fougeres du terrain houiller du nord 

 de la France,* is inclined to accept Boulay's suggestion. 



The specimens from Radstock are similar to Brongniart's type figure. 



Sphen. Grandini appears to me a very distinct plant, though, according to- 

 Boulay, even it may be only a variety of Sphen. furcata, Brongt. This latter 

 species has not yet been observed in the Radstock area, where Sphen. Grandini, 

 though rare, is widely distributed. 



The ferns figured by Geinitz and Lesquereux as Brongniart's plant 

 belong to another species.t

 figs. 1-3. 



Remarks. — Of very unfrequent occurrence. 



Dr Stur is evidently in error in separating Geinitz's and Gutbier's figures 

 from Sphen. macilenta, L. & H., — a species in which the pinnule cutting 

 varies much according to the position the pinnae hold on the frond.J 



Localities : — Radstock ; Braysdown ; Camerton. 



Sphenopteris Woodwardii, Kidston, n.s. 

 Plate XIX. fig. 1. 



Description. — Frond tripinnate ; rachis very stout ; primary pinnae sub- 

 opposite, ascending; secondary pinnae alternate or subopposite, lanceolate, 

 ascending ; pinnules alternate, oblong-lanceolate, pinnatifid, rarely divided into 

 lobes ; veins distinct, veinlets usually simple, occasionally bifid, — especially in 

 those pinnules which are divided into lobes. 



Remarks. — The specimen figured is the only example of this species with 

 which I have met. It was collected on one of my earlier visits to Camerton, 

 and though diligent search has since been made for additional specimens I 

 have not yet succeeded in securing any. 



The pinnules are most commonly merely pinnatifid, as shown at fig. la. 

 The limb of the pinnules is of very delicate texture, but the veins are thick
