A very remarkable species, which may bear some relation to B. Potanini 
Maximowiez (B. sphalera Fedde) from Shensi and Kansu, of which the sys- 
tematic position is yet unknown. B. Potanini seems to be well distinguished by 
its lanceolate, smaller, coriaceous leaves, containing a hypoderm, and by its 
shorter inflorescence. 
Our new species is dedicgted to His Most Serene Highness Prince Johann II. of 
Liechtenstein, to whom the author feels himself much indebted for help in his 
dendrological studies.
