Der Artikel handelt über eine im Münchener Herbar liegende 

 Pflanze aus dem Herbar Schreber, welche von Linne 

 Schrebera ochinoides genannt, von Schreber in einem Brief

 Cuscuta africana Willd. schmarotzt. (Dies wurde übrigens

 complicirte Synonymie zur Folge, auf welche hier nicht ein- 

 gegangen werden kann. Neger (Eisenach).
