II. On the organisation of the fossil plants of the coal-measures. Part XII

At the recent meeting of the British Association at York, Messrs. Cash and Hick read a memoir, since published in Part IV of vol. vii of the “Proceedings of the Yorkshire Geological and Polytechnic Society,” in which they described a stem from the Halifax Carboniferous deposits characterised by a form of bark hitherto unobserved in those rocks. To this plant they gave the name of Myriophylloides William sonis. It was characterised by baying a large cellular medulla, surrounded by a thin vascular zone composed of short radiating lamellæ.
