 Schimp. (Bot. Mag. Tokyo. XXVI. p. 304-306. 1912.) 



Kulturversuche mit dem Leuchtmoose gelangen leicht, wenn 

 man nur eine kleine Menge der Erde, auf welcher das Moos wächst, 

 auf humusreiche Gartenerde bringt, und die Kultur massig feucht 

 hält. Trockenlegen und Durchtränken des Bodens sind schädigend. 

 Die Lebenszähigkeit des Leuchtmooses ist auffallend. Es ist ein vor- 

 zügliches Objekt für Demonstration der Beweglichkeit des Chloro- 

 phyllapparates infolge der wechselnden Lichtrichtung. Als Natur- 

 denkmal muss der erste Fundort des Leuchtmooses in Japan 

 erhalten bleiben. M. J. Sirks (Haarlem).
