Having completed this description we compared it with 

 the gênerai descriptions of the wood-anatomy of the 

 several familles, published in the two first volumes of 

 our „Mikographie des Holzes". It was soon found that 

 the only family with which the characters of Aptiana 

 coincided and did so in a very satisfactory manner, was 

 Indeed that of the Ternstroemiaceac. 



We now sought in this family among the species of 

 which a full description was given, for that which corres- 

 ponded' in the largest number of most essential characters 

 with Aptlana. We found that this was the case with 

 Eurya acuminata and we reproduce hère a literal translation 

 of this description, as given in our Mikrographie, but 

 somewhat shortened for the reader's convenience, by 

 omitting ail those characters of which no mention is 

 made in the description of Aptiana. 



If the reader will compare the two descriptions with 

 each other, he can judge for himself of the validity of 

 Aptiana'a claim to be considered as a member of the 

 family of the Ternstroemiaceae.
