In the winter of 1928 several parties were sent by the Geological survey of Kwangtung and Kwangsi to the northern part of Kwangtung for Geological researches. In those excursions many important tcoal-mines were visited, accurate geological maps of the important coal-fields have been surveyed and a very large number of specimens of rocks, minerals and fossils have been collected. Among those specimens there are a large number of plantfossils which are well preserved and good for deter-mination. A part of them collected from the coal pits of Keng Kou in the neighbourhood of Kou-Ya Tung Coal-field on the boundary between Kwangtung and Hunan provinces belongs to the Lower Jurassic age, while the other part collected from the neighbourhood of La-Shih-Pa and Tien-Lo-Chung Coal-fields belongs to the Permian age, to the horizon of Gigantopteris flora. The Jurassic plants we shall discuss in the second part o fthis volume. In the present paper only Permian plants are discussed. The rocks within which the plants embedded are mainly shales. They are either of campact, dark, coally shales or of softer gray shales. The fossils are on the whole of good state of preservation and a few ferns carry even the sporangia. A large number of Gigantopteris specimens are the best indicators of the geological horizons.
