The fossil plants which form the subject of this paper were forwarded to me by Mr. David Draper, of Johannesburg, and my thanks are due to him for affording me the opportunity of making the following contribution to the palæeobotany of the Southern Hemisphere. The localities from which the specimens were obtained are briefly described in the foregoing communication by Mr. Draper, who expresses the view that the beds of each horizon are probably of the same geological age, namely, the lower portion of the Stormberg Beds of Dunn. The evidence afforded by the plants is, however, strongly in favour of a lower horizon; it points to a Permo-Carboniferous rather than a Triassic age. The interesting association of genera brought to light by Mr. Draper's discoveries, and its significance from the point of view of geological age and plant-distribution, will be best discussed after a description of the individual species. The following are the principal localities from which the plants were obtained:— (1) Boschmans Fontein and Maggies Mine in the: Middelburg district, Transvaal; (2) Casey's Township (Francis), 2 miles south of Johannesburg; and (3) Vereeniging, about 30 miles south of Johannesburg. In a paper by Schmeisser on South African minerals there is a reference to the occurrence of Glossopteris and Schizoneura in the Middelburg district at the: Holfontein Colliery. The rocks are spoken of as belonging to the Stormberg Series. From the second locality, under the name of ‘Francis,’ M. Zeiller has recently described the following species:— Glossopteris Browniana , Brongn., G.
