196 NATURAL HISTORY. [NORTH 
appear to exhibit an internal structure intermediate be¬ 
tween that of the Lycopodiacae and the Coniferae ; but 
Lepidodendron punctatum of Sternberg, of the unique 
specimen of which, in Mr. Cotta’s collection, a portion is 
seen in CaseC., 6,) presents the organization of a real arbo¬ 
rescent fern. Nearly allied to the Lepidodendra are seve¬ 
ral vegetable fossils, considered as distinct genera, among 
which may be specified Lepidopliyllum and Lepidostro- 
bus (Case D.) of Brongniart, (the forrfier perhaps only 
the leaves, the latter the fruits of species of Lepidoden¬ 
dron or Lycopodiles ,) the Ulodendron ( Lepidod . ornatis - 
simutii , Sternb.), the Bothrodendron of Lindley, the Rhyti - 
dolepis of Sternb., &c. 
In the upper division of Case 5 are placed the species 
of Sigillarici , (including Favularia ,) Brong., which are very 
distinct in their structure from arborescent Ferns, with 
which they have by some been arranged. To these also 
belongs the Megaphyton Nohd.; of which the original spe¬ 
cimen figured and described by Artis is deposited here. In 
the lower division of the same Case, are seen some very in¬ 
teresting vegetable remains, some of which undoubtedly 
are referable to the family of Asphodelea:, such as the 
Dracaena Benstedii (from the Iguanodon quarry near 
Maidstone) so called after the discoverer of the fine spe¬ 
cimens presented to the Museum. With these are placed 
magnificent specimens, from Dr. Mantell’s collection, of 
the Clathraria Lyellii from the Wealden : the generic 
name, formerly synonymous with Sigillaria, is now ex¬ 
clusively given to this remarkable vegetable. Stern - 
bergia transversa of Artis, ( Artisia of Sternberg,) hitherto 
described and figured from very imperfect specimens, 
also probably belongs to this natural order. Another 
interesting vegetable of Dr. Mantell’s discovery is the 
Endogenites erosa , of which many specimens from Hast¬ 
ings, &c., are deposited, exhibiting its structure : it seems 
related to the Palmse, and is no doubt a congener of 
Cotta’s Porosus marginatus , of which a specimen is 
added ; but neither of those generic appellations appear 
to be admissible. There are also remains of real Palma: 
in this Case, such as the fruits from Sheppey, the cut
