Most of the leaves included in the. Fig. 430. Dolerophyllum Goepperti. Bud in surface-view, A; in longitudinal section, B, C; in transverse section, D. (British Museum; A, f nat. size.) bud were attached to the axis below the broken base. The curved, dichotomously branched, veins are seen on some of the pieces of lamina on the surface of the bud (fig. 430, A). The considerable breadth of the leaves is demonstrated by the longi- tudinal and transverse sections. In fig. C most of the laminae can be traced through the whole height of each of the steep-sided arches: a few overlapping margins are seen in fig. D. The veins are for the most part imperfectly preserved and appear as clear ' No. V. 8114. ^ A specimen from Orenburg in the Dresden Museum shows the same surface- features as the British Museum specimen and agrees with the originals of Goeppert's figures which are in the Breslau University Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Seward, A.
