Das Rotliegende von Oppenau gehört dem Unter-Rotliegenden 

 an, das von Hinterohlsbach und Durbach, Bottenau und Meh- 

 len grün d gehört ebenfalls dem Unter-Rotliegenden und zwar der 

 Kuseler Stufe an. In der Gegend von Baden-Baden wurde von 

 früheren Autoren Unterschied gemacht zwischen einem unteren , 

 mittleren und oberen Rotliegenden. Nach Verf. gehört jedenfalls der 

 überaus grösste Teil dem Mittel-Rotliegenden an. 



Für den Vergleich mit anderen Floren muss ich auf das Ori- 

 ginal verweisen. In den Nachträgen werden zahlreiche Verbesserun- 

 gen und Zusätze gegeben, welche durch mehrere Abbildungen 

 illustriert werden. Jongmans. 



Fpeeman, E. M. and B. J. C. Umbergep. The Smuts of Sorg- 

 hum. (Circular N". 8, Bureau of Plant Ind., U. S. Dept. of Agri- 

 culture, 1908.) 



The grain and kernel smut, Sphaceiotheca sorghi , and the head 

 smut, Sphaceiotheca reüiana, are briefly described. The kernel smut 

 is the most widely distributed occuring almost universally where 

 Sorghum is grown. Directions are given for the formalin treatment 

 and also for the hot water treatment for this trouble. In either case 

 it is very important that extreme care be taken to prevent infection 

 of the seed after treatment. The hot water treatment is just as efifi- 

 cient as the formalin and is much cheaper. 



The life history of the head smut is not known at present, but 

 it is known that the treatment recommended for the seed has no 

 effect upon the head smut. The necessary precautions and proper 

 treatment for the sorghum crops as a whole are summarized at the 

 close of the circular. R. J. Pool,

Smith, E. F., The Granville Tobacco Wilt. (Bull. 141, part IL 

 Bureau of Plant Ind. U. S. Department of Agriculture. 1908.) 



The tobacco wilt has been studied for a number of j'-ears and 

 is now regarded as solely bacterial in its origin being due to Bac- 

 terimn solanaceanmt , the common bacterial disease of many Sola- 

 naceous plants both cultivated and wild. The main signs of the 

 disease are: wilting of the foliage, darkening of the veins, dark
