Abstract
Archaeopteris notosaria sp. nov. based on one fertile and numerous ste rile leafy branches is described from the Grahamstown By-Pass locality , Witpoort Formation (Witteberg Group) Upper Devonian, and represents the first unequivocal record of the genus in southern Africa. This occ urrence is used, in its palaeogeographical context, to support the sug gestion that climatic gradients in Late Devonian times were less steep than they are at present.
