In dieser Lieferung findet man japanische Beschreibungen und 

 Abbildungen folgender Pflanzen: Otherodendron japonicuni Makino 

 (Taf. XII. XIII, XIV), Prunus serrulata Lindl. var. sachali}iensis

 zeichnungen. Es ist, der ausgezeichneten Tafeln wegen, sehr zu 

 bedauern, dass die Beschreibungen vollständig in japanischer 

 Sprache gehalten sind und sogar nicht einmal eine Tafelerklärung 

 in einer der geläufigen Sprachen beigegeben ist. Jongmans.
