European Angiosperms

In our „Mikrographie des Holzes der auf Java vorkom- 

 menden Baumarten" we are trying to show that important 

 results in systematic Botany can be obtained by anatomical 

 investigations concerning the v^ood, if thèse are conducted 

 with siifficient care. For this purpose descriptions of the 

 anatomical structure are necessary, made v^ith careful 

 observance of the rules given by Linné for describing 

 the external appearance of plants. Of course some additions 

 to thèse rules and some altérations hâve been necessary, 

 because anatomical and morphological facts belong to 

 somewhat différent orders of things and because the 

 microscopic method présents peculiar difficulties. But in 

 the main it is the Linnean method we appîy. 



The results obtained in the two first volumes of our 

 work are from a systematic point ofview most satisfactory,, 

 which wo hope will become still more apparent, when
