lieved by the inhabitants of Etorofu to have great virtues in hysteria, and is largely brought 

 back by the Japanese sailors and fishermen who visit this island. It is known there by 

 the name of JBenizarasa.

Var. kurilensis. A straggling shrub; the bark of the young branches grejush or grey- 

 ish-brown and glabrous; leaves appressed-hairy above, and more or less villose along 

 the veins beneath, orbicular or roundish-oblong, or sometimes obovate at the end of the 

 branches, rounded or obtuse at the base, abruptly cuspidate at the apex, 7-12 (9)-veined, 

 prominently incised-serrate ; teeth spreading, 1-3-serrate, and glandular at the tips; pedi- 

 cels villose; drupe purplish-red (nearly ripened) ; putamen oval, smoothish, with three 

 nearly parallel veins near its keeled edge. The petiole measures 10-15 mm. long; the 

 blade, 70 X 52-85 X 60 mm.; the cuspidate tip, 8-12 mm.; the peduncle, 22 mm. long, 

 and the putamen, 8x5 mm. 



Hab. In exposed hill tops along the coast; Etorofu, at Rubetsu and Shibetoro. 



All that I have seen in the above mentioned localities are straggling shrubs about 

 three or four feet high. They may grow larger in less exposed places. 



The plant is most closely related to Prunus Ceraseidos, Max. The shape and character 

 of the putamen, in these two plants, agree very well. The only prominent points of dif- 

 ference between them are in the form and texture of the leaves. In Prunus Ceraseidos, 

 they are broadly elliptical or obovate, and long-cuspidate, and their texture is less cori- 

 aceous than that of the Kurile plants. Such differences, however, may be accounted for 

 by the difference in their localities. In the absence of flowers (which are well charac- 

 terized in Prunus Ceraseidos by the great development of the calyx-tnbe), it is difficult 

 to form any decided opinion as to whether the Kurile plants should be separated from 

 that species or not. So far as my materials allow me to judge, I am inclined to regard 

 it provisionally as a variety of Prunus Ceraseidos. 



Prunus Ceraseidos has been collected, thus far, only in the alpine and subalpine woods 

 of middle Japan.
