217. — Lepidophyllum lanceolatum, L. etH. Type specimen, F.F., pi. 7. 

 There are two Lepidophyllum leaves on the slab. The one 

 figured is about an inch and three-quarters long, with a dis- 

 tinct thickened midrib. The other leaf is smaller and placed 

 edgewise in the shale. 

 Loc. — Shale above the Bensham Seam, Jarrow. (iJ. C. 455). 



218. A large, nearly perfect bract or leaf of the fertile spike, 



with strong midrib, and part of the triangular spore-plate or 



-scale attached to the base of the leaf. 



Loc. — Shale above ihe Bensham Seam, Jarrow. (H. C. 458). 



Remarks. — ~No one ought to have any difficulty in admitting 

 that the specimens figured as Lepidodendron dichotomum, Sternb., 

 •Vers., tab. 2, and the specimens figured by Lindley-Hutton, 

 Fossil Flora, Plate 7, f. 1, and Plate 8, represent corresponding 

 parts of the same genus and species of fossil plant. They repre- 

 sent also, I think, younger branches and leaves of the stems 

 referred to Lepidophloios laricinus, Sternb. The Halonia gracilis, 

 Foss. Flora, Plate 86, copied by Brongniart, from Low Moor, 

 Yorkshire, is no doubt the same species as L. acerosum of the 

 same authors; and the Lepidostrobus pinaster, Plate 198, is un- 

 doubtedly a small portion of the stem of the same plant, which 

 in Hutton's figure the artist has furnished with leaves, repre- 

 sentations merely of fractures on the surface of the shale. Pinus 

 anthracina, L. etH., Fossil Flora, Plate 194, represents the leaf- 

 cushions of a small piece of the stem of L. laricinus, preserved 

 in a matrix of rough conglomerate from the Coal-measures. Mr. 

 Kidston refers L. acerosum, L. et H., and Lepidostrobus pinaster, 

 L. et H., to the Lepidophloios carinatus, Weiss, but I consider 

 these to be small branches of L. laricinus ; and the leaf-scars in 

 L. acerosum of the above Nos. 207 — 210 have these scars near the 

 apex and not at the base of the leaf-cushions, and therefore I 

 think that these leaf-scars in the drawing of Lepidostrobus pin- 

 aster, L. et H., F. F., Plate 198, are not shewn in their true 

 position, and further, the drawing copied from Goldenberg by 

 Schimper, Plate 64, f. 4, is, I think, not reliable as to the true 

 position of the leaf-scars of this plant. The specimens of L. 

 acerosum quoted above have tufts of leaves at their extremity,
