über winterliche Reservestoffspeicherung in den Bäumen unserer 

 Zone an. Der Verf. fand dass ausser den von Fischer genannten 

 Bäumen noch die folgenden als Fettbäume zu bezeichnen sind : 

 Salix Caprea, S. piirpurea, S. caesia, S. nigra, S. fragilis, S. nigri- 

 cans und einige ausländische 5«/?xarten, ferner Betula nana, B. 

 hwnilis, Castanea sativa. S. babylonica enthält in äussersten Jahres- 

 ring viel Stärke, desgl. 5. repens. Als Stärkebäume waren ferner 

 hervorzuheben: Carpinus httulus, C. duinensis, C. yedoensis, C. cor- 

 data, Juglans nigra, J. regia, J. niandchurica, Carya porcina, Ostrya 

 carpinifolia, abweichend von Fischer fand Verf. in Robinia viscosa 

 ziemlich viel Stärke. Keine Stärke und trotzdem sehr wenig Fett 

 wurde in folgenden Bäumen nachgewiesen: Alniis incana, Populus 

 balsarnifera, Salix caprea, S. ptirpurea, Carpinus cordata u. a.; was 

 aus der verschwundenen Stärke geworden war konnte nicht nach- 

 gewiesen werden. Neger. 



Se-ward, A. C, On a Collection of Fossil Plants from 

 South Africa (Quart. Journ. Geol. Soc. LXIV. p. 83—108 with 6 

 plates and 7 textfigures. 1908). 



The specimens described, with one exception from the lowest 

 bedsofthe Beaufort Series, belong to the Molteno and Burghers- 

 dorp beds of Cape Colony. After briefly discussing the subdivi- 

 sions of the Karroo Series of Cape Colony, the author describes 

 the following species. Schisoneura is represented by 5. Carrerei Zeill., 

 the specimen of which consists of portions of slender branches, 

 bearing numerous, long, filiform leaves, the axis being characterised 

 by narrow and slightly-prominent ribs and indistinctly-marked nodal 

 regions. Other specimens also referable to the same genus, but not 

 specifically identifiable, are impressions of the external surface of 

 the stem, and of pith-casts. In one case both are seen on the same 

 specimen. Schisoneura africana Feistm. is also described. 



The characters of the genus Thimifeldia are next discussed and 

 illustrated at some length, being compared with those oi Ctenopteris 

 and Ptilosainites. Attention is called to the variable character of 

 Thinnfeldia odontopteroides (Morris). A new species, T. sphenopteroides 

 is described and figured. 



Danaeopsis Hiighesi Feistm., an Indian species, is described from 

 South Africa for the first time. Another genus new to Cape Co- 

 lony is Odontopteris , of which a new species O. B rowni is founded. 

 Cladophlebis (Jodites) Roesserti (Presz) and Taeniopteris Carruthersi 

 Ten. Woods, complete the list of fern-like plants. 



Baiera is represented by a new species B. moltenensis , and 

 Stigmatodendron , by a new species S. dubium. An axis of a cone 

 with appenda^es, but without seeds, is described as a new species 

 of Strobites, S. laxus. Two examples of Pterophyllum , not specifically 

 determinable, though one of them may be compared with P. Tietsii 

 Schenk, are also discussed. 



The paper concludes with a list of all the plants known from 

 the Stormberg Series (including the Molteno beds) and from the 

 Burghersdorp beds. The new species described afford further evi- 

 dence for assigning the former to a Rhaetic horizon, but the latter 

 appear to belong to a somewhat lower horizon, though the flora 

 does contain a certain number of Rhaetic types. All the specimens 

 described are figured, and a very füll bibliography is appended.
