Abstract
In a Note published in the Annals of Botany for December 1899, I gave some account of the structure of two stems from the Lower Carboniferous of Scotland, provisionally named Araucarioxylon fasciculare, sp. nov., and A. antiquum, Kr. (Witham, sp.).In the present paper these stems are described fully, with the help of illustrations, and others, presenting similar points of interest, are added. The species dealt with are the following:—Calamopitys fascicularis (Araucarioxylon fasciculare of the Note).Calamopitys beinertiana (Araucarioxylon beinertianum, Kr.), (Göpp., sp.).Pitys antiqua, Witham (Araucarioxylon antiquum, Kr. of the Note).Pitys Withami (Pinites Withami, Lindl. & Hutt.).Pitys primœva, Witham.Dadoxylon Spenceri, sp. nov.Keywords
