„ „ TTrophlyctis hemisphaerica (Speg.) Syd. 



[The species was describedias, Uromyces hemisphstricaby Spegazzini, and since 

 then has been redescribed under various other names. It causes galls on 

 the stems. Bowletiatenera in South America and in Europe is found on 

 Carum Carvi and Pimpinella magna.] Ann. Mycol., i. (1903) pp. 517-S.

Lichens. 



Lichen Flora of Heidelberg.*— W. Ritter von Zwackh-Holzhausen 

 published in 1883 a Flora of this region. Since that date he had added 

 largely to his collection, and was arranging for the publication of the 

 new list, when he died. Hugo Gluck has taken up the task, and pub- 

 lishes the revised and enlarged list compiled from von Zwackh's 

 notes. The species number 559. Nylander's classification is followed 

 throughout. 



Contributions to our knowledge of the Chemistry of Lichens.t 

 O. Hesse has studied the constituents of Lichens, and gives an account 

 of the various substances he has found in the different forms. A 

 number of these are new discoveries : Pannarol, Areolatin, Areolin, 

 Poronin and Talebraracid, etc. He gives the chemical formula? of 

 these and of some of the other substances. In Evernia furfuracea he 

 found a new constituent Furevernacid, but he failed to find Everniol 

 or Olivetoracid.
