macrospores, and showed that it belonged to a plant o^ 
the carboniferous epoch. It has long been supposed that 
Lepidostrobus was the fructification of Lepidodendron, but 
no further evidence of the fact had been adduced than that 
which Dr. J. D. Hooker, F.R.S., had given by finding the 
cones in the insides of Lepidodendron Harcourtii and 
elegans, which could only be considered of a very unsatis- 
factory nature. In a cone in the author’s possession in 
every respect similar to the late Dr. Robert Brown’s cele- 
brated specimen of Triplosporite, but having the column 
in a more complete state of preservation, there is most 
conclusive evidence from internal structure that the Trip- 
losporite is the fruit of Lepidodendron Harcourtii, the pith 
vascular cylinder, vascular bundles communicating with the 
leaves or scales, and the outer cylinder being the same in 
the cone as in the stem, thus justifying Mr. Carruther’s 
opinion, that the cone was a Lepidostrobus. The large 
spores found in a Lepidostrobus described by Dr. Hooker 
in the 2nd volume of the Memoirs of the Geological Sur- 
vey, as well as similar specimens found by the author in 
coal at Wigan, and described in the Quarterly Journal of 
the Geological Society for May, 1849, are most probably 
both macrospores of the fructification of Lepidodendron, 
and having come from the lower portion of a cone, whilst 
Dr. Brown’s were from the upper part. The same may be 
said of Professor Morris’ specimen belonging to Mr. Prestwich 
from Colebrook Dale, described and figured in vol. v. of the 
Transactions of the Geological Society, published in 1840, 
which clearly came from the lower portion of a cone of 
Lepidodendron. 
In the new genus Flemingites, described and figured by 
Mr. Carruthers in vol. ii. of the Geological Magazine for 
October, 1865, there are two kinds of sporangia, those in 
the upper part of this long and slender cone being some- 
thing like the sporangia of the Lepidodendron, but ar-
