JAPAN. Hondo: prov. Suruga, slopes of Fuji-san, abundant above alt. 

 300 m.. May 7, 1914, E. H. Wilson (No. 6637, type; bush or small tree, 0.9-4.5 

 m. tall, 9 ; No. 6637% c^ co-type). 



This is a curious form, looking somewhat like a hybrid between S. iEeinii Franchet 

 & Savatier and a species of sect. Albae. The old cf flowers have a very small dorsal 

 gland. Unfortunately there are no mature leaves. The habit seems to be different 

 from that of all the species of sect. Albae resembling S. Reinii, which is appar- 

 ently a common plant at the type locaUty. 



The specific name is derived from aKyia-ros, very difficult.
