 prov. Suraga, Mt. Kuno, only by seaside, March 15, 1911 (ex Herb. Sakurai; 

 flowers, old fruits). 



The typical A. firma is a southern plant growing by the seaside, while the fol- 

 lowing subspecies grows on the mountains and in the more northern partsof Japan. 

 It seems so closely alhed to the type that I cannot separate it as a species. 



This is a very common shrub or low scrubby tree in Kyushu and particularly so 

 on the open exposed slopes of Higashi-Kirishima. A picture of this Alder ^^^' fi^ 

 found under No. xl05 of the collection of my Japanese photographs. E. H. W.
