and the integumented megasporangia of certain Palaeozoic Lycopods 
on the other. The latter organs present close analogies with true 
seeds, but are wholly distinct in detailed structure from the Gymno- 
spermous seeds above mentioned. 
The discovery of the specimens of the new cone is due to Messrs. 
J. Lomax and G. Wild, who recognized it as a Cardiocarpon- bearing 
strobilus, resembling a Lepidostrobus b 
The original specimens, which are calcified and generally well 
preserved, were derived from the Ganister beds of the Lower Coal- 
measures, some from Hough Hill, Stalybridge, others from Moorside, 
Oldham. Numerous sections were cut by Mr. Lomax and Mr. Wild. 
A closely similar fructification occurs, at a much lower horizon, in the 
Burntisland beds of the Calciferous Sandstone Series. 
The strobilus is of the ordinary Lepidostrobus type. The cylindrical 
axis bears numerous spirally disposed sporophylls, each of which 
consists of a long horizontal pedicel, expanding at the distal end into 
a rather thick lamina, which turns vertically upwards. 
Anatomically, the structure is also that of a Lepidostrobus. The 
stele which traverses the axis has a narrow ring of centripetal wood, 
and a large pith; the leaf-trace bundles which pass out to the sporo¬ 
phylls are collateral in structure, and agree closely with those described 
by Mr. Maslen in Lepidostrobus Oldhamius 1 2 . 
The ligule is sometimes well preserved; it is seated in a depression 
of the upper surface of the sporophyll, at the distal end of the 
porangium, and is thus in the normal position 3 . 
With one exception, the specimens of the strobilus are immature, 
and their tissues not quite fully differentiated. These younger 
specimens bear sporangia which are essentially those of a Lepidostrobus. 
A single large sporangium is seated on the upper surface of the 
horizontal pedicel of each sporophyll, to the median line of which it 
is attached along almost its whole length. 
The sporangium narrows out towards the top, and terminates above 
in a well-marked ridge ; in general form it resembles Williamson's 
Cardiocarpon anomalum , but in the immature condition there is no
