Abstract
A collection of plants was forwarded by the writer to Mr. A. C. Seward, M.A., F.G.S., for identification. These were found at the following localities, marked on the accompanying map. All these localities are situated within the area which is known to be coal-bearing, excepting No. 2, Casey's Township, which is a small outlier, detached from the main body by denudation. The coal-bearing rocks of the Transvaal belong to the horizon which is known in South African geology by the name of ‘Molteno Beds,’ the lower member of the Stormberg Beds (Dunn), generally assumed to be of Triassic age. The accompanying sections (figs. 2 & 3, pp. 312, 313) demonstrate the position of the Molteno Beds with regard to the underlying rocks. It will be seen that they rest unconformably upon tilted strata, beneath which the beds are generally believed to be of Carboniferous age, though but few fossils have been found in proof of this assumption. In general, and especially at Vereeniging, a boulder-bed, containing large rounded masses of quartzite, conglomerate, dolomite, and other rocks, all of which have evidently been derived from the older series exposed to the northward, lies upon the eroded surface of the underlying rocks; this boulder-bed apparently represents an ancient beach-line, no traces of which have as yet been found at a higher level than the present outcrop of coal-bearing rocks.
