The leaf-scars on the smaller shoots occur on elongated cushions (fig. 212, C, D) with a transversely wrinkled surface; on the older branches the leaf-scars are separated by fairly large areas of bark characterised by sinuous transverse grooves and narrow ridges bearing numerous small pits, as shown on an enlarged scale in fig. 212, A. The original surface-features are shown on the left of the drawing, and a slightly deeper level in the cortex is represented on the right-hand side. The absence of leaf-cushions on the older shoots is probably the result of secondary thickening, which also alters the size and shape of the leaf-scars. Each scar has three pits on its surface, as in _Lepidodendron_; a central leaf-trace scar and lateral parichnos scars. The circular pit above the leaf-scars, which occurs in most species, marks the position of the ligule. The relation of the short leaves, 5 mm. long, to the leaf-cushions is shown in fig. 212, D. The absence of leaves, except in impressions of slender twigs, may be interpreted as an indication that they were shed at an early stage and did not persist many years. The leaf-cushions of the smaller shoots of _Bothrodendron minutifolium_ closely resemble those figured by Weiss on a Devonian plant, _Lepidodendron Losseni_[616]. One of the few examples so far discovered of a Bothrodendron cone is shown in fig. 213; this specimen, at least 10 cm. long, was found by Mr Hemingway in the Middle Coal-Measures of Yorkshire and described by Dr Kidston. Numerous sporophylls are attached at right angles to the axis, the surface of which is protected by their upturned distal portions; the arrangement of the parts appears to be the same as in _Lepidostrobus_. A specimen figured by Zeiller as _Lepidostrobus Olryi_, which Kidston is probably correct in identifying with _Bothrodendron minutifolium_, shows that each sporophyll carries a horizontally elongated sporangium (fig. 212, E). _b.
