30 A History of Botany, 1860-1900 



Zopf's treatise on the Fungi was another noteworthy 

 volume which appeared in 1890. Von Tafel contributed 

 a work on Brefeld's lines in the Vergleichende Morphologic 

 der Pilze, 1892. We must also mention Istvanffy's Unter- 

 suchungen tiber die physiologische Anatomie der Pilze, 1896. 



Haberlandt's Physiologische Pflanzenanatomie was one of 

 the remarkable books of the period. It was published in 

 1884 and was received with great favour. It aimed, as its 

 title suggests, at interpreting anatomical detail by physio- 

 logical need, and discussed the classification of the tissues 

 from this point of view. 



The indefatigable industry and the clear insight of 

 Strasburger led to the enrichment of literature by the 

 addition of many classical memoirs and treaties. Of these 

 the following were the chief : Die Befruchtung bei den 

 Coniferen, 1869 ; Die Coniferen und die Gnetaceen, 1872 ; 

 Ueber Bejruchtung und Zelltheilung, 1878 ; Die Angiospermen 

 und die Gymnospermen, 1879 ; Ueber Zellbildung und 

 Zelltheilung, 1880 ; Bau und Wachsthum der Zellha'ute, 1882 ; 

 and Bau und V errichtungen der Leitungsbahnen, 1891. 

 These enshrine the results of those magnificent investiga- 

 tions associated with his name. 



The end of the century (1899) witnessed the appearance 

 of Solereder's Systematic Anatomy of the Dicotyledons-, an 

 attempt to utilize anatomical characters for purposes of 

 classification. 



Neither French nor English literature can compare with 

 German writings of the time. Of contributions to the former 

 the most important were Le Maout and Decaisne's great 

 work of 1868 on Classification, and Van Tieghem's Treatise 

 of 1891, which was memorable as presenting to the scientific 

 world his now well-known theory of the stele. 



In England the Genera Plantar um was almost the only 

 really notable publication which appeared. Brought out 

 by Bentham and Hooker in the years 1862-1888 it stands
