“ Note on the Organs of Fructification of Calamodendron,” 
by E. W. Binney, F.R.S. 
In my paper on Calamodendron, published in Yol. XXI. 
of the “ Transactions of the Palseontographical Society,” 
p. 27, is figured and described a plant with organs of fruc- 
tification attached to it from the lower Brooksbottom seam 
of coal near Ewood Bridge, in the county of Lancaster. 
The plant consists of a stout stem, having traces of ribs and 
furrows, and seven joints at which knots appear. From 
these last-named parts, on each side of the stem, are seen 
to proceed seven cones, all about half an inch in length, 
springing outwards in nearly a horizontal direction in the 
specimen. These cones do not show any trace of a central 
axis ; but are composed of crown-shaped masses, most pro- 
bably of sporangia, contained in receptacles, arranged around 
an axis. Eight or nine of these can be seen in one cone. 
Unfortunately, the specimen being in soft shale, no evidence 
can be obtained of its internal structure, so as to ascertain 
if the sporangia contained any spores. If this is not the 
same plant as Geoppert’s Aphyllostachys Jugleriana it is 
very closely allied to that plant. 
Mr. John Aitken, of Bacup, furnished me with the speci- 
men. At the time the Monograph was published my opinion 
was that the only point in which the specimen differed from 
that figured and described by Ludwig of the fruit of Catamites 
in Bunker and von Meyer’s Palseontographica, Yol. X., 
1861 to 1863, was that it only possesses 8 to 9 recep- 
tacles or cells against his 15 to 16. 
Since that time Captain Aitken, of Irwell Yale, and Mr. 
John Aitken, have been so good as to conduct me to the 
place where the specimens were found, and I have collected 
myself far more perfect and complete specimens than those 
which had previously come under my observation. 
In both Ludwig’s and Geoppert’s specimens the cones or 
organs of fructification, like the leaves, were arranged in
