4 NOTICE OF A FOSSTL LYCOPODIACEOUS FRUIT. 
In respect of the latter family, I united to the large stems and 
branches which form the genus Lepidodendron certain spikes, or cones 
of fructification, which appeared to me to be the cones of these gigantie 
Lycopodiacee, and which I designated by the name Zepidostrobus. 
Since then, these relations have been completely confirmed by the 
observations of Dr. Joseph Hooker on several specimens of Lepido- 
strobus,* enclosed in nodules of carbonate of iron, from the English 
coal-field, the internal structure of which had been so well preserved 
as to exhibit, much better than I had seen, the form of the sporangia 
borne on the scales of these cones, and the nature of the spores con- 
tained in them. 
Another specimen, remarkably well preserved, the origin of which 
was unknown, had been previously described by our illustrious asso- 
ciate R. Brown, under the name of Triplosporites. His profound study 
of this specimen in 1847, and the additional observations made in his 
memoir in 1851, after the examination of a beautiful specimen which 
I showed him in 1849, convinced him of its intimate relations to Le- 
pidostrobus, from which he hesitated to consider it as generically dis- 
tinct. 
But the specimen described by Robert Brown,t as well as that of 
the Museum at Strasbourg, half of which had been given to the Mu- 
seum at Paris, and which I showed him, presents only short portions 
of those cones ; that described by Robert Brown belongs evidently to 
the summit of a cone; that which I had studied appeared to proceed 
from its base, but the perfect specimen which is the subject of this 
notice shows that it rather belonged to the middle portion of one of 
these spikes of fructification. Indeed, the lower portion of these cones 
presents very remarkable differences of organization, which must mate- 
rially modify the characters ascribed to these fossils, and appear to in- 
dicate greater differences between them and Lepidostrobus than one 
would have supposed, if the organization of these latter fruits has 
been fully understood from the specimens atorar by Dr. Jong 
Hooker.
