This species, which is less abundant than _B. minutifolium_, in British Coal-Measures, has been described by several authors as _Ulodendron_ on account of the occurrence of large depressions, like those shown in fig. 211, on certain branches of the plant. At the suggestion of Dr Kidston, Prof. Zeiller[618] figured an English specimen of this species, presented to the Paris Museum by Mr Hutton, in which the leaf-scars are preserved on the bark of a stem with Ulodendron scars. The surface of the bark is characterised by numerous small pits and discontinuous vertical lines in contrast to the transverse lines of _B. minutifolium_ (cf. fig. 212, A and F). The leaf-scars on the smaller shoots may have a diameter of only 0·3–0·5 mm., while on the larger branches they reach a breadth of 1 mm. The ligule-pit may be in contact with the upper edge (fig. 212, F) of the leaf-scar or separated from it by a short distance. [Illustration: FIG. 213. _Bothrodendron minutifolium_ Cone.
