ORGANIC REMAINS OF TILGATE FOREST. 23S 
Vegetables. — These consist of the petrified 
trunks of large plants, belonging to that tribe of 
vegetables of the ancient world, which is so common 
in the carboniferous strata, and appears to have 
held an intermediate place between the Equiseta 
and the Palms ; of tire stems of a gigantic mono- 
cotyledonous vegetable *, the foliage of ferns ; and 
the stalks of arundinaceous plants. Of these, the 
most interesting is that which has been described 
as Clathraria anomala, in the Geological Trans- 
actions ; but as we had ])reviously named it in 
honour of Charles Lyell, Esq., F. R. 8., &c., the 
autlior of the “ Principles of Geology,” a work 
which jilaces its author among the most distin- 
guished of modern geologists, we claim the pri- 
vilege of original discoverers, and retain that 
specific designation. 
Clathraria Lyellii. Plate L figs. 1.2. 6. 
This vegetable appears to have possessed a thick 
epidermis, or false hark^ formed by the union of 
the bases of the leaves, and covered externally with 
distinct rhomboidal scales, each scale being sur- 
rounded by an elevated ridge. These cicatrices, 
or scales, have evidently been formed by the 
attachments of the petioles of the leaves, or by the 
bases of the leaves themselves ; the form of the 
latter is not positively known, although from some 
imperfect traces on the stone in a specimen bearing 
the impressions of the cicatrices of the bases of the 
leaves, there is reason to conclude that they were 
of a lineari-lanceolate form. The axis, or interior 
part of the trunk, originally enclosed by the bark, 
occurs in the state of solid subcylindrical blocks of
