Lepidodendron koivirnsf, nov. sp. 

 PI. VI., Fig. 2. 



This species is founded on certain decorticated stems in which 

 circular or elongated protuberances stand on vertical ridges, each 

 row of protuberances being set alternately to those on either side : 

 the protuberances again are divided bj' horizontal furrow.s. The 

 surface of the stem outside the furrows and ridges is Mat and 

 smooth. The protubei-ances have a central pit where the leaf-trace 

 bundle came through. 



Similar stems have been hgui'ed bj' Dawson under the name 

 Lepidodendron gaspianuin from the Upper Devonian (Catskill 

 group) of North America*, and from Australia under the name 

 L. australe, M'Coy, by FeistmanteD. M'Ooy brings this latter 

 species in verj' close relation to L. tetragonmn, Geinitz from the 

 Carboniferous of Saxony, so that the two can hardly be dis- 

 tinguished"^ ; Kidston refers Feistmantel's Australian L. nofhum 

 Unger, to this species'*. It is to this species that I would refer the 

 specimen bearing leaves figured by Mr. Seward in the text of his 

 description of the fossil floras of Cape Colony obtained from 

 Atherstone quarry, Kowie (Port Alfred*). I have myself obtained 

 many specimens of lepidodendroid stems from a road quarry or. 

 the west of the river, and there are a great number of specimens 

 in the Albany Museum from, a tunnel driven into the side of the 

 hill near the railway station, Port Alfred, which was made for the 

 purpose of following a carbonaceous shaly band between the
