It is well possible that the cyclonic trajectories were displaced north- ward in winter by at least 10° latitude, so that they could in certain localities reach the 24th parallel of latitude. During interglacial maxima the reverse development will have taken place and tropical rain could freely penetrate the Transvaal while the Orange Free State and the Cape Province would generally have had a fairly dry to very dry climate as the winter rain did not touch the south-western Cape area regularly. ENVIRONMENTAL CHANGES The impact of the drastic climatic changes on the vegetation will be treated in more detail elsewhere (Van Zinderen Bakker Sr 1976). On purely theoretical grounds certain vegetation reconstructions can be implied, but is not yet possible.
