In the original description of this plant by Salter,’ he 
states that “‘ the leaves are very indistinct, but about 4 of 
an inch long, lancolate (obtuse ?) and much curved upward 
to one side (the upper side probably). There is some indi- 
cation of their being set on in spiral lines, instead of 
quincuncially.” This points directly to the probability of 
the plant having a prostrate, creeping habit of growth 
after the manner of our modern Lycopodium clavatum, and 
is a view well borne out by all the specimens which have 
passed through my hands. This resemblance is also 
heightened by the fact that the extremities of the branches 
in L. milleri are often somewhat swollen exactly as may be 
seen in a growing plant of Lycopodium clavatum. This, Sir 
Wm. Dawson has regarded as the possible fruit,” but I 
should rather consider it as representing the terminal bud. 
The leaves show no distinct articulations with the stem nor 
do they, on removal, leave upon the latter well defined 
scars as in Lepidodendron, though the spiral arrangement 
common to both these genera might be regarded as an indi- 
cation of affinity, but of very subordinate value. While 
the character of the fruit in Lepidodendron is fairly well 
known,’ it is as pointed out, wholly unknown in Lycopodites. 
A distinction of this genera must for the present, therefore, 
be based upon the superficial structure as represented in 
the leaves, leaf scars and general form and aspect of the 
plant. 
From this point of view I have carefully compared 
Lycopodites milleri with Lepidodendron gaspianum which 
Kidston regards as identical, employing for this purpose 
specimens preserved in the same matrix, i.e., sandstone 
shale, in order to ensure that the plants were subjected to 
similar conditions. I find that while in the former, the 
leaves closely overlap so as to render their points of inser-
