39G MR ROBERT KIDSTON ON THE FOSSIL FLORA OF THE 



Lepidostrobus spinosus, Kidston, n. sp. 



Lepidostrobus, Brongniart, Hist. d. vcget. foss., vol. ii. pi. xxii. figs. 2, 3, 8. 



Remarks. — A single specimen of a cone, similar to that figured by Brong- 

 niart (loc. tit.), has been collected. Though this fossil is rare in the Radstock 

 Series, it is of frequent occurrence in some of the British Coal Fields. 



Locality ; — Braysdown Colliery. 



Lepidostrobus, sp. 



Remains. — There is placed here a cone, the exposed portion of whose bracts 

 is rhomboidal. It appears to be a well-marked species, but is only represented 

 by a single specimen. 



Locality : — Radstock.

dendron punetatum) ; Annals and Mag. Nat. Hist., 5 th ser., vol. xvi. p. 251, pi. iv. fig. 5 ; 



pi. v. fig. 8; pi. vii. figs. 12, 13 (excl. syn. Sig. Preuiana and Bothrodendron punetatum). 



Remarks. — -Very rare. The leaf-scars in the specimen placed here are not 

 distinctly preserved, but from what is discoverable of their form they seem to 

 agree with those of Sigillaria (Ulodendron) major, especially with that form 

 described as U. minor by Lindley and Hutton. 



As I find Lindley and Hutton's name for this plant has priority over 

 Lepidodendron discopliorum, Konig, the former author's specific designation is 

 now adopted.* 



Locality : — Radstock. 



Sigillaria Serlii, Brongniart. 



Sigillaria Serlii, Brongt., Hist. d. veget. foss., p. 433, pi. clviii. fig. 9. 

 Sigillaria Serlii, Carruthers, Geol. Mag., new series, Dec. ii. vol. x. p. 49, 1883. 



Remarks. — I only know this plant as occurring in the Radstock Series from 

 the figure given by Mr Carruthers in the Geol. May. 



Long grass-like leaves, the Cyperites bicarinata, L. & H.,t similar to those 

 shown in Mr Carruthers's figure, are common throughout the whole of the 



* I hope presently to publish my reasons for still retaining these Ulodendroid-Lycopods in Sigillaria, 

 a position which some botanists are not inclined to accord them. — May 1887.
