"A tree 30 to 35 meters tall, girth 2.1 to 3 meters. This is a woll- 

 marked species characterized by the narrow hut stiff erect catkins 

 and by the fine denticulations of the short-petioled leaves. The 

 bracts are rather short, with obtuse or acute lobes, tbe middle one 

 being twice longer than the erect lateral lobes. Tins remarkable 

 birch is rare in Japan, and I saw it only on the wooded shores of 

 Lake Chuzenji and in the ascent there from Nikko. It is a large
