I have the specimens collected by me on Mt. Kiyosumi in 

 the province of Awa (Boshu), April 1898, which bear a \QYy 

 closel}^ allied appearance to this pubescent form, but the 

 serration of the leaves are different ; probably it is a hybrid 

 between Prunus pseudo-Cerasus a. Jamasakura Makino and 

 P. incisa Thunb. I have given it a new name of Prunus 

 affinis Makino. The leaves are pubescent on both surfaces, and 

 the serration is rather regular and duplicate, with a pubescent 

 petiole. Flowers coetaneous, 3-3|cm. across, 2-3, corymbose ; 

 common peduncle surrounding by the obovate or obovato- 

 spathulate (in the inner ones) pubescent (in the inner side) 

 perulae at the base, thinly pubescent ; pedicels thinly pubescent ; 

 bracts obovato-oval, serrulato-fimbriate. Calyx-tube tubuloso- 

 campanulate, glabrous, about 5-6mm. long ; segments ovate 

 or deltoid-ovate, acute. Petals elliptical, emarginate, 



var. /?. borealis Makino.
