Hab. 

 Bonin : in rupibus mentis Tsutsuji3'ama insulae Chichishima (T. 

 Nakai et H. Toyoshima), 



This is only Azalea found in the Bonin-groups. It grows on the 

 clifFv summit of mount Tsutsujiyama (.4^a/ea-mountain), to which 

 man can access with utmost difficulty. The foliage resembles to 

 Rhododendron Simsii and the flowers to R. ledifolium. Special cares 

 should be necessary' for its cultivation, for we all failed both in Bonin 

 and Tokyo, even with young plants carefulK' removed and nursed.
