double rows of oval scars commence, which at first incline consider-
ably to the right, but soon take a vertical direction and run exactly
parallel to each other. There are no traces of longitudinal furrows,
either upon the bark or the decorticated stem. The intervals between
each pair of scars swell outwards, the raised spaces being exactly
under the projecting wrinkles on the surface of the bark, as showTi in
fig. 2, which is a vertical section, of the natural size, in the direction
of one of the double rows of leaf-scars, d, e being the bark, and/, g
the deep indentations on the decorticated stem.

The inner surface of the bark is covered with minute scales, which,
to the naked eye, appear not unlike the delicate rhomboidal markings
of a very young Lepidodendron, but when viewed through a lens

exhibit an oval outline, as shown in fig. 3, which is
magnified three times the natural size. These scales
are quite distinct as far down as the point h (fig. 1),
a few inches below the first ramifications of the roots.
The roots a, b are marked with irregular waving strise,
occasionally running one into another, as represented in
figs. 4 and 5, the first being the upper, and the second
the lower side, of the same piece of root. It will be
observed that the areolae on the upper side are squeezed
into an oval shape, sometimes to such a degree that
merely a black indented mark is visible, whilst on the under side they
